Months ago in Fodlan...
"HAAAAAH!" Byleth launched a powerful slash as it broke Solon's barrier and then cut him down. Solon's blood was spilled as he cried in agony as he fell down.
"So this... that I would lose to mere beast..." He weakly said as he glared at Byleth. "But this is not the end. Thales will carry out our mission...somehow..." He said before he died.
"Thales..." Byleth clench the Sword of the Creator. 'I better remember that name...'
"Professor, are you all right?" Edelgard asked as she appoached him.
"I'm fine. Thank you for asking." Byleth turn to her.
"I'm relief to hear you say that... But that hair... and those eyes... you reminded me of someone. What happen to you?"
"Hmm... I'm not sure if you would believe it... but the Goddess gifted me her power."
"The Goddess?" Edelgard eyebrow. "I see... Well, I'm haooy for you. Your weapon is called the Sword of the Creator after all. It's no wonder she looks favorably upon you. Just as it was with saint Seiros, no doubt..."
"I... suppose so..." Byleth said as he close his eyes as he look sad.
"Is something the matter Professor?"
"Nothing... I'm just glad it's over... My father's killer is dead. It's a shame I couldn't take her head... but I can relax... knowing he has been avenge."
"I suppose you're right. So Professor, may I ask you somehting. Just how will you use this new power?" Edelgard asked
"That's a good question." Byleth stare at his hand while looking lost in thought. "I could say numbers of things. Like for the world, and for my students. I want to use this power to protect... protect the people... and protect those I cherished."
Edelgard let a small snickered. "That is so like you to say. Tell me, if the world, and your students included were to divide and go to war with each other, what would you do?"
"What would I do?" Byleth turn to her in confusion before Byleth suddenly felt a little sleepy.
"In that scenario, each side would represent both the world and your students. Who would you-" Then Byleth suddenly collapses on the ground. "Professor?" She ran up to him in surprised from his sudden collapose. Then notice Byleth was asleep. "Have you... Fallen asleep?!" She wondered as she thought for a moment. She sighed. "This must be a side effect of youe recent... changes. I can't just leave you here. I could try carrying you, but..." She shake her head. "No, I had better call for Hubert."
"You summoned me, Lady Edelgard?" Hubert appoached as he and the others appoached her. Beforing noticing Byleth changes. "His hair and eyes..."
"Is that... really Professor Byleth?" Avery asked in surprised. "I know and remember how he came back to us but..."
"His hair color..." Flaynn quietly gasped and said.
"Where's that old bastard? And where's Kronya?" Caspar asked as he look around.
"They're both confirmed dead." Hubert answered. "Our mission has been accomplished. While the sudden changes from Professor Byleth puzzles me."
"Indeed. Hubert, I want you to carry him back to the Monastary." Edelgard said.
"Understood, Lady Edelgard." Hubert nodded.
"Let us help at least." Ferdinand said. "Wouldn't it be better if me or Avery carry him? We both have the horses borrowed from the monastery after all."
"It's fine. I'm more then capable of carrying Professor Byleth." He said as he begin to bend his knee down as Edelgard and Dorothea help pick him up, then place him on Hubert's back. Hubert then got up. "Let us be off."
Back to Garreg Mach Monastery...
The Black Eagles return to the monastery as they approached the gate and enter the Entrance Hall.
"You're back!" Seteth said as she, Rhea and few Knights of Seiros appoached them. "Was the mission a success?"
"Yes, the enemy has been routed, but there's more." Edelgard nodded as the Black Eagles turn to unconscious Byleth.
"More? What do you-?" Seteth turn to Byleth and then he gasped. "What?!"
"P-Professor Byleth hair color change? I-It resembles that of Lady Rhea! What does this mean?" A Knight of Seiros asked.
"I-I'm not so sure, what happened?!"
"According to the Professor, the Goddess gifted him her power." Edelgard answered
"What!?" Seteth exclaimed. "But... how?"
"I'm not so sure myself. But he needs rest. He exhausted himself."
"Take him to the infirmary. Then we can discuss this afterword." Seteth command as they nodded and take Byleth to the Infirmary. Once they arrived. They place him into the bed. Then Edelgard and Hubert left.
A few moments later. Someone enter the Infirmary. And that someone is Rhea. She made a small gasped as she stare at Byleth. "It's true..." She whisper as she covered her mouth and smiled. Almost broken into tears. "I can't believe it... it worked..." She approached Byleth, pick him up and headed to the Audience chamber where no one is watching. She close the door, headed to the throne, and then sit down by the stairs, then place Byleth's lap on her knee. "After so many attempts... finally... you finally merge with Sothis." She smiled as he brush Byleth's hair. She close her eyes and begin to sing. "In time's flow...see the glow of flames ever burning bright... On the swift river's drift, broken memories alight..." Rhea then heard Byleth's groaned and then she witness him opening his eyes. "Professor. You must remain still."
"Where am I? What happened?" Byleth asked as he feels sleepy.
"Everything is all right. There is no need to worry. Those who are trying to harm you are far away." She smiled as she begin to hummed.
'Those who are trying to harm me? Does she mean... Solon and his accomplish? Why do I feel so sleepy all of the sudden?' Byleth thought as he try to keep his eyes open but he still feels tired. 'It's been so long since I felt this exhausted before... how long has it been?'
"How lovely...it would be for this moment to last forever...?" Rhea asked as she pets Byleth's forehead. "I wish I could hold on to this time we have stolen... that you and I could create a world without end... I have heard whispers of what happened to you. Your appearance... You have received power from the goddess. From the moment you took hold of the Sword of the Creator... I prayed that one day the radiant power of Sothis, which bathes Fódlan in its celestial light, might reside within you. But you are so much more than the light. You are my..." She paused but she shake her head as she smile. " Close your eyes, dear one. Sleep, just a while longer."
Byleth close his eyes and sleep.
"I will be watching over you, always. Always and forever..." Then Rhea heard the door knock. "Who is it?"
"Lady Rhea, it's me. Brianna." Brianna answered on the otherside of the door.
"Brianna? You may enter." Rhea said as Brianna, Byleth's twin sister enter the Audience Chamber.
(Fire Emblem Three Houses ost - Gazing at Sitris)
"I've return Lady Rhea. I heard news about my brother. I went to check up on him and-" She look down and saw her brother in her lap. "Huh!? Wh-What's he doing here and-"
"Shhh. Your brother is asleep, Brianna. Please speak quietly." Rhea said with her finger to her lips.
"S-Sorry..." Brianne said as she look down at her brother. "It's true..." She said quietly. "His hair... they suddenly changed... What... How did this happen? Did... Did the goddess really gifted him her power?"
"Yes. The goddess Sothis indeed send her power to your brother. This is the joyous of news." Rhea smiled. "Your brother avenge your father. I'm so proud of your brother..."
Brianna look down for a bit as she clench her fist. 'Why wasn't I part of getting revenge on Jeralt...? And why was HE gifted the goddess power... Just... what is going on!?'
"Is something the matter Brianna? I sense anger." Rhea asked as Brianna look up and see Rhea looking at her.
"It's nothing..."
"That expression said otherwise... Ah..." Rhea look down sadness. "You wanted to avenge your father, didn't you?"
"One reason... yes." Brianna said as she look away.
"Ah... I see... My apologize Brianna... I should have allow you to join your brother as your brother requested..."
Brianna turn to her in surprised. "Brother...wanted me to go?"
"He did. But I heard you were in much grief from your recent argument with him."
"I see..."
"But Brianna... Your brother also took your anger into his and avenged your father. He knows that you love your father as he does. You know that, don't you?"
Brianna said nothing but nodded.
"I know that Jeralt will be happy to know he's been avenged. May I ask a favor of you?" Rhea asked.
"What is it?" Brianna asked.
"Can you bring Byleth back to the infirmary? I'm sure Manuela or the others might be looking for him."
"Yes... I'll take him back to the infirmary." Brianna said as she begin to pick up her brother and then take him back to the Infirmary. As she walk. All in her thought was. 'I just don't get it...'
(BGM ended)
The Next day
Byleth walk out of the Infirmary and then begin to look around. Of course he expected many within the monastery would gossip of his new hair and eye color. And then there are rumors that he received Sothis's power. As he look around, he spotted Edelgard near the classrooms.
"Edelgard." Byleth appoached her.
"Oh, Professor Byleth. How are you feeling?" Edelgard asked.
"I feel the same as usual. Have you seen Brianna?"
"I saw her in the Training Ground today. She must be worried about you from your exhaustion yesterday."
"I hope so... I have... much to talk about her."
"I see... I heard you and Brianna got into an argument yesterday." Edelgard said. "Something about the past?"
Byleth sighed. "It's a long story... Let's save that for another time. Thank you for telling me where she was."
"Of course Professor Byleth." Edelgard nodded as she Byleth left.
(Xenoblade Chronicles 2 ost - Elysium in a Dream)
Once Byleth arrived. She saw Brianna sword training herself. Soon she stop swinging her sword.
"You want something Byleth?" Brianna asked
"Yes. Can we talk?" Byleth asked.
"I don't see why not. What is it?"
"Let' talk in my room... It's more private there."
Brianna sighed. "Very well." She shealt her sword and then follow Byleth to his room. Then arrived and Byleth close the door. "What do you want to talk about. Is this about your newfound power from the goddess?"
"Well, that... and... well a lot. Listen Brianna... I'm sure you heard I avenged Father by killing Monica... but her real name is Kryona... Listen I-"
"Lady Rhea told me you wanted to invite me to avange father... but because of our argument... I didn't come out of my room." Brianna said.
"I see... Listen Brianna... I really did want you to come along... that we can avenge father together...But... because of what I said... I only ended up hurting you again... I'm so... so sorry... I couldn't face you after that. By the time we left... and the moment I saw her face... I felt nothing more but rage towards her...
-Flashback-
Byleth was clashing with Kronya. Kronya slashed Byleth all over but Byleth was able to keep up the paste. Blocking and parry her attacks with ease. As Kronya was getting irritated, she forward charge her attack, Byleth step on her tow, causing her to lose balance and then he punch her in the face hard enough to send her flying and crash into a tree.
"GAAAAAH!" Kronya wailed in pain as she fell onto the ground with black liquid from her lie on the ground for a moment, coughing and sputtering but she's not dead. She look at Byleth who's approaching her menacingly and as she look in fear.
"You have no idea how much I want to make you pay." He said glaring at her as he appoached. "You took my father... right in front of me. I don't know if that was bold of you, or foolish. You have no idea how much pain and suffering you cause both me and Brianna... Because of you... My sister and I never felt so heartbroken. Because of you, we got into an argument... and it's all. Your. Fault... I will make you pay for killing Father... I will make you pay for hurting Brianna! YOU WILL PAY WITH YOUR LIFE!"
Kronya flinched with such rage, she got up but weakly and tried to run away from him in the woods.
"GET BACK HERE!" Byleth yelled and chase after her.
-End of Flashback-
"Although I couldn't get her head... I did avenge our father. I took your rage and mine during our fight. Even Leonie." Byleth said as he tough his heart.
"I see... How thoughtful of you..." Brianna said as she close her eyes.
"Listen, Brianna... I know what I've done in the past was unacceptable. That I mock you, and that I criticize you. And I took the life of the mercenary too seriously... You and I know that... Except... I was like a doll. While you... you were more human than I am. Mercenaries lives end shortly... That what father taught us. But... now... it all change... I was... becoming human..."
"Becoming human, hm? You're right about that. You certainly change after the past few months. So tell me, what cause this change?"
"I don't know... but... I think it was when I started to interact with people for once. And when I was sudden teaching the class... witnessing their growth... listening to their complains, and offering advise with the best of my abilities." Byleth touch his chest. "I felt...something within me awoken... I can... feel things... understand more things. It hit me. I was beginning to feel proud of my students... and... memories of our training... and father's words of wisdom and comfort... I felt... warm and love. I though there was something wrong with me... but it turns out... They were my feelings... awoken. I begin to experience a lot of chances... and one of them was... the death of father. I never felt so much pain, grief and sorrow before... And when I saw Kronya... I felt nothing but to cut her head off... making her feel the pain by stabbing her and hearing her scream. Dark as that sound... I never felt so much rage within me. Knowing how that felt... I took your rage and Leonie onto her. But even after killing her... I couldn't feel peace... Brianna... I wanted to apologize for all that I have done." Tears begin swelling in his eyes. "I was ashamed to hurt you like this... you endure so much of me. I was nothing more of a bastard. I know you don't deserve a brother like me. You deserve better. I don't blame you for hating me for twenty years. You earn that right. If you want to punch me and let out your frustration... go ahead. ."
Brianna blicked "You... actually want me to hurt you."
"Yes. I deserve every last of it. And I won't hold it against you if you place me in the Infirmary. I don't deserve your forgiveness."
"I see..." Brianna close her eyes before opening them as she approach her brother.
Byleth close his eyes, ready for the impact. However, instead of the impact of punches, he felt a warm embrace. "Huh?" Byleth look and see Brianna hugging him.

(Pokemon Super Mystery Dungeon ost - Partner's Theme Music Box)
"I forgive you brother. I can't deny that you were one hell of a douce and a bastard... And I endure twenty years of frustration... but you really have grown into the person I hope you'll be. But even being so mad at you... I still love you, my beloved brother. All I wanted is for you to apologize... and now you did. It took you long enough... But it was worth it. Why don't we start all over? That's the only thing you'll get from me." Brianna smiled as she look at her brother.
More tears swell in Byleth's eyes "Brianna..."
"It's okay." She lay her head on her brothers chest as she smile and rubbing her brothers back. "Let it all out."
Byleth hug back and let out his tears. For the moment later, Byleth pulled away and dry his tears. "Thank you...Brianna."
"Feeling better?"
"Yeah. More better than ever... I feel... more at peace now..." Byleth let out a smile.
"I'm glad to hear that." Brianna smiled. "Because now I can do this." Then she begin to tickle her brother.
"Bwahah- hey, cut it out, ahahaha!" Byleth laughed until Brianna stop and hug her brother again as they both laughed.
"There... Much better..." Brianna giggled. "So, was there anything else you want to talk to me about? Is this about your sudden changes?"
"Yeah. But first." Byleth then turn to his door and look with a flatface. "How long are you guys going to eavesdropped?"
Then they heard a thud from outside and Byleth open the door. Then revealed that Ingrid, Annette, and Dimitri who were eavesdropping the whole thing.
"Bah! Professor Byleth! How did you know?" Annette asked.
"I've notice during the middle of the talk."
"Sorry Professor, we didn't mean to eavesdrop. But we couldn't help but feel concerned." Ingrid apologize with a bow as Byleth cross his arm.
"R-Right. After all, news about your sudden changes... and then the rumors that you and Brianna got into a fight. We all were." Dimitri added.
"I never picture you the type to eavesdrop on a lady, Dimitri. Did Claude influence you?" Brianna teases. "Speaking off, Claude, I know you're there."
"Seriously, how the heck did you know I was here?" Claude exclaimed as he came in.
"Unbelievable you guys." Byleth sighed. "But pretend this didn't happen. We just work out something from our past. And that I was a bastard. But there's something else I wish to talk to her about... privately."
"Yes of course. Our apologies. I'm just glad nothing happened between you two." Dimitri said as he and the others begin to walk out.
"Oh and Dimitri." Byleth called out to him. "I expect you to... look out for you know who."
"Ah! O-Of course." He said as he light blush and ran off.
Brianna giggled. "Did you seriously have to tell him that?"
"I did. I am your older brother after all." He said as he close his door. "Now, where was I? Ah yes. There's something you should know." He said and then begin to tell her everything.
"I see... So she's now merged with your soul..." Brianna hummed.
"Yeah... I can no longer hear her voice." Byleth nodded.
"I'm sure she has no regrets. After all, you did what you had to... to return to me... to everyone. Just... don't so anything reckless... Okay?"
"I won't. Thank you, Brianna. You haven't told anyone about that secret?"
"The Divine Pulse? No. It's between us."
"Good. It would be best that way. I shouldn't keep you waiting."
"Right. I got to continue my sword training. Catchcha later." Brianna waved and left her brother's room.
(BGM ended)
"Later." Byleth smiled as he begin to look around in his deck and then found a letter. "Hmm? A letter?" He pick it up and see the Smash Bros emblem. "Huh? Who sent this?" He examines it before opening it. Then read the letter. "Dear Byleth Eisner. We are pleased to inform you that we invited you to join the world of Smash Bros as one of our Fighters." Then suddenly the letter glow. "Huh?!" Then Byleth has suddenly warped away.
Byleth then reappeared in front of Smash Bros Castle lobby as he look around.
(Kingdom Hearts II ost - Olympus Colosseum.)
"Wha- What is this!?" Byleth exclaimed.
"Welcome Byleth! We have been waiting for you!" A booming voice called out and appeared Master Hand and Crazy Hand.
"Wha- Giant hands?!" He nearly pulled the Sword of the Creator.
"Easy there Byleth! We're not your enemies." Crazy Hand crackled.
"It is as my brother said. Allow me to introduce ourselves. I am Master Hand. I am the creator of Smash Bros. A fighting tournament where you can fight Fighters of other worlds."
"Other... Worlds?" Byleth blinked.
"That's right. You know the term, outrealm?"
"Yes?"
"Good. It's like that. We have many fighters here in the World of Smash. Each from different worlds. similar or different from your very own. Why we even have villains who are Fighters." Master Hand then begin to talk more about smash and later time-consuming."So, you understand?"
"Let me see if I got this right... You invited me... into your world of roster. Where I'm forced to fight against my will?"
"Goodness no! Nothing like that!" Master Hand exclaimed
"Although..." Crazy Hand chucked before Master Hand smash him on the head... er... over the hand? I don't know!
"We're not kidnapping you or anything like that! Think of it as a facility where you can hone more of your skill with fighters from different world. You'll love it here. And if you wish to visit other worlds. You just need to ask us and we'll let you. This is the benefit of a Fighter here in the Smash Bros World."
"I see... Well, I guess I can accept this." Byleth said.
"Great! Welcome aboard Byleth! Oh yeah. We're also inviting your sister as well."
"My sister?" Byleth blicked.
"Yep! In any second..." Crazy said and then a flash appeared and appeared Brianna. "Here she is!"
"Byleth!?" Brianna exclaimed.
"Brianna!" Byleth also exclaimed
"Okay, where am I?!"
"Allow us to explain!" Crazy Hand said.
"A Giant Talking hand!?" Brianna exclaimed
"Not your enemy. Now let me give you the detail!"
"Shouldn't they just bring me and Brianna together next time..." Byleth sweatdrop.
After the exclamation to Brianna...
"I know many people love you! Your game is very popular!" Crazy Hand exclaimed
"My what?" Byleth title his head.
"A game?" Brianna was also confused
"Ignore him. Allow us to introduce you to everyone!" Master Hand said bringing out a microphone. "Everyone, can I have your attention, please? We like to introduce you to a new Fighter that join Smash!" And soon and later. All the Smashers begin to enter the lobby. "Everyone, welcome Byleth and Brianna! From the Fire Emblem Three Houses!"
The Fighters begin to clap their hands and applied.
"Fire... Emblem? Three Houses?" Byleth title his head.
"I have no idea what's going on..." Brianna sighed
"So remember everyone, welcome Byleth and Brianna with open arms!" Master Hand then pushes them towards the others Fighters and then the hero fighters begin to introduce themselves to them. Sooner and later. Byleth enter a fight against Mario, Then Team Battle with Pikachu against Ganondorf and Samus. And Brianna fight against Zelda.
Soon three hours has passed...
Byleth wipe the sweat off his forehead.
"That certainly was time confusing..." Byleth sighed and noticed Brianna chatting with Peach and Samus. "It was nice of them to show me a way back to my home... I should head back. Everyone must be wondering what happened to me."
"Excuse me, Byleth?" A voice called out as Byleth turn and see Palantina approaching him.
"Oh... You're Palantina...The Goddess of Light, right?"
"That's right. I've notice something while we met. You merge with Sothis right?"
"Sothis? How do you know her?" Byleth asked
Palutena smiled. "I'm a goddess, and I've met Sothis in the past. One day, she mysteriously disappeared… and now here we are."
"How do you know she merged with me?"
"I recognize that hair color anywhere." Palentina answered as she opened up a door leading to Skyworld. "Come, we're going to fix this." She took his hand.
"W-wait a minute! What about-"
"Don't worry, I'll find out a way for to keep this newfound power of yours!" Palentina said, dragging him into the door and closing it behind them.

In the Temple of Light in Sky World...
(Kid Icarus Uprising ost - Solo Menu)
Palentina conjured a chair with her staff. "Mind sitting down?"
"Um... sure?" Byleth sit on the chair as Palentina cast Byleth into a coma.
Palutena closed her eyes and aimed her staff at him, her staff orb begin to glow. "Almost there…" Palutena whispered as a big ball of light appeared near the two. "Almost… there…" She whispered as the ball of light grew brighter until eventually, a Sothis appeared before the two. "I've done it!" She grinned. "Awaken, Sothis!"
"Mmm… aaagh…" Sothis yawned. "Mmm… What in the world…?" She looked around the area. "I'm not in that dark room anymore?" She wondered and spotted Byleth. "Oh for crying out loud! Byleth, what's with you and comas! I swear it's every-… wait, why am I awake and he isn't?"
"Hello!" Palutena waved as Sothis turned
"Palutena?! Wh-what's going on here?" Sothis asked.
"I brought you back… and outside of Byleth. You're yourself again."
"Holy…" Sothis whispered and then hugged Palutena. "Thank you!"
"You're welcome." She smiled and then she aimed her staff at Byleth to wake him up.
"Mmm…" Byleth groaned a bit as he woke up and saw Sothis in front of him. "Wha…?"
"Morning, sleepyhead!" Sothis teased as Byleth suddenly grabbed her cheeks, stretching them out of curiosity. "Mmmph! Wath… wath are you doing?"
"…Just making sure you're not imaginary."
"Do I look imaginary to you!"
"Yes." Byleth answered
"Oh ha ha!" Sothis slap Byleth's hand off.
"Honestly... this surprised me so much. I never thought you would be brought back. Although perhaps the work of a God is capable of such things."
"Well us gods have power over several things." Palutena said. "Now then, we should also have you keep your newfound powers."
"Ah yes. Now that I think about it... Do I still have my heart?" Sothis asked.
"Not yet. Sorry Byleth, but I'm gonna need you to be asleep for a moment." Palunetina said and put Byleth into a coma again.
"I swear the whole coma nonsense." Sothis sighed.
Palutena closed her eyes and aimed her staff at him, her staff orb begin to glow. "Gotcha..." Palutena whispered as a big ball of light appeared and then the light brought out Sothis's heart. A.K.A. her crest stone. "Aaaand..." She whispered as the ball of light grew brighter and then it go into Sothis and then Sothis begin to glow with a celestial light. "Now that's done. But let's activate his heart." She said as her staff glowed again and Byleth was glowing. Byleth's heart for the first time started to beat. "Yes!" She smirked. "And with that. Sothis is whole again and Byleth's heart is now normal functions." Then she snap her finger and awaken Byleth.
Byleth yawned "Ahh... mm..." Then he rub his eyes. "Please tell me that's enough of the comas..."
"Yep. Also, I activated your heart."
"My heart?" Byleth touch his chest and for the first time, his heart skip a beat. "My... heart...!"
"Yep. Now, for you to keep your newfound powers. Sothis, I'm gonna need your help on that."
"I know. Byleth. I'm gonna need you to drink my blood." Sothis said as she appeared to be whole again.
"What?!" Byleth exclaimed. "Why would I do that?!"
"Because one, I can make it easier for you to give you the Divine Pulse. Second. It's also for the Sword of the Creator. Which, we need to tinker with it." She then made a small cut on her arm and conjured a cup and pour her blood on it. Once it's appersiate. She heal her cut mark. "Drink." She offer it to Byleth.
Byleth look sicked. "I don't think I can."
"Oh just hurry up."
Byleth sighed and then take the cup of Sothis's blood. He gulp and then close his eyes and begin to drink it. Once he drink it fully. Then Byleth begin to glow for a bit his hand conjured the Crest of Flames. A Major Crest of Flames. The Glow Fade. "This is..."
"Yep. Now you have my blood. We can begin." Sothis nodded and then begin to use her powers onto Byleth and allow him to use Divine Pulse. "There."
"Now for the Sword of the Creator." Paluntina said and then she and Sothis begin to use their powers and tinker with it. Once that was done. It can be use like he usually do. "And we're done!"
"Great! Now then, let us return to Fodlan... I have some scolding to do with that daughter of mine."
"Wait... Who's your daughter?" Byleth asked.
"Rhea."
"Rhea's your daughter?!"
"Yes. Rhea was the last of my children before Nemesis and those despicable Agathans killed them! I will have vengeance against those detestable arrogant beasts! The Agathams are those people you face. Like Solon and Kronya. They're an ancient enemy of mankind ever since I punish them for their arrogance and think they can challenge me. It was I who gave them knowledge and build their society. But they became arrogant later on and think themselves as Gods. They turn on me and my children. But we eventually defeated them. But it cost a great damage to Fodlan. I use all of my strength to heal it. But because of them. I was weakened and went to sleep to recover. Nemesis was a bandit who the Agathan use to kill me. Take my bones and heart and force the Sword of the creator. Then kill the rest of my children and gave the Twelve Elite their blood and weapons made out of their bones! The Hero Relics were actually made with the bones of my children. They committed so many unforgivable crimes and horrific actions. And they claim to be saviors of the world and humans are beasts. When They are the beasts themselves. I will not let them get away with it. They must be exterminated." Sothis explained
"So that what happens..." Paluntina close her eyes.
"I... I can't believe this..." Byleth trailed off.
"Yes. Byleth. I ask you to keep the truth about the Heros Relic a secret for now." Sothis said.
"Why?"
"I don't know what Rhea was thinking rewriting history. But I'll let them keep it that way for now. It would cause some confusion. And I can't have that happen."
"I see... I understand." Byleth trailed off.
"Good. Now, I need to make an entrance. And probably enter that form." Sothis sighed. "Let us be off."
Byleth nodded and Paluntina open a portal back to Smash Bros Castle. Then they return and looking for Brianna.
"Brianna." Byleth called out for her.
"Oh, there you are. I was wondering where did you ran off." Brianna said before noticing Sothis. "Who's this?"
"I am Sothis. The Goddess of Fodlan."
"S-Sothis!? This is what she looks like? I was expected more adult then a child!"
"I am not a child! This is the form I most adore!"
"It's a long story. I'll tell you when we get home." Byleth said.
"Oh... Okay..." Brianna trailed off as Sothis snap her finger.

Back in Byleth's Room.
Byleth and Brinna reappeared in Byleth's room.
"This is your room." Brianna said. "Wait, where's Sothis?"
"She's making her entrance." Byleth answered. "Okay, I'll explain."
With Sothis...
"Hmm..." Sothis appeared over the Cathedral. "Rhea should sense my presence. But..." She snap her finger and appeared in the adult form. In her adult appearance. She appears just like insignia of the Church of Seiros. "It's been awhile since I appeared in this form. But, time to descent." She said and then her body begin to glow and head to the glass of the Cathedral.

Inside was Mercedes and Marianne who were praying with the other people who are praying. Then suddenly the glass begin to glow and that caught their attention. And then descent from the glass.
"W-What's going on?!"
"T-The glass is glowing!"
And then descend down was Sothis. As the people gasp within the Cathedral. Sothis landed on her feet and then open her eyes. As the people gossip. One look at the insignia and regonize who she was.
"I-It's the Goddess Sothis!"
"The Goddess Sothis!"
Soon there was an uproar in the Cathedral as they all got up and approached Sothis and bow to her and calling out her name. Soon more are coming and some are the Knights of Seiros, and some are students of the academy. Soon Rhea, Seteth, Flaynn and Manuela appeared. Rhea gasped as she covered her mouth as she see her mother right in the distance. Sothis look at Rhea who fell on her knees.
"Lady Rhea?!" Seteth exclaimed.
"M-M..." Rhea couldn't say mother as tears swell in her eyes.
Soon Sothis begin to approach Rhea as the people of the church step aside. Once she appoached Rhea. She offer her hand.
"We have much to discuss." Sothis said in a mature voice.
Rhea took her hand as more tears swell as she nodded. Sothis turn to Seteth. "May I ask you to keep news of my return a secret for now?"
"W-What? But-" "All will be explain. Can you do it?"
"Y-Yes of course!" Seteth bow and then turn to everyone. "Everyone! Calm yourself!"
"Rhea. Let us be off to the audience chamber." Sothis said.
"Yes." Rhea wipe her tears and then guide Sothis there.
(BGM ended)
In the Audience Chamber...
(Fire Emblem Three Houses ost - Gazing at Sitris)
"It has been so very long since I return to Fodlan, Rhea." Sothis said.
"Y-Yes, Mother... I... I can't believe it... You return!" Rhea said while wiping her tears. Soon Sothis embrace Rhea with a hug.
"You have done so much to avenge me Rhea. I couldn't be more proud of you."
"Thank you so much mother... Is this a dream? I've waited so very long for this day...!"
"Yes. Although I have returned to Fodlan. There are some things I am displeased with you." Sothis said.
"W-What?" Rhea gasped as Sothis turn to her with a glare as she tap her feet impatiently.
"What were you thinking child? Explain yourself!"
"W-What do you mean, mother?"
"You know what I'm speaking about! Rewriting History, make Fodlan a close nation, meddling in the affairs of life and death. I can go on many times the actions you and the church have created. And over the pasts month when I was in that vessel, I remember the things you done. Such as Lord Lonato of Gaspar." Sothis answered as she cross her arm.
"Mother… I have had my reasoning…" Rhea answered as she look down.
"And WHAT good reason is that?! Did you honestly expect this to go on for much longer?"
"I… You were dead mother. I was just doing what the church wanted!"
"No. This is what YOU wanted. You should not meddle in the affairs of life and death."
"Mother please understand! I wanted to heal the suffering I've endure and return to life I once knew." Rhea stated.
Sothis sighed as she pinch her nose. "I suppose... I cannot fault you. Despite all that. I'm grateful for the love you have done. Also, I question how you manage to put my conscious into the vessel. I'll leave that aside for now. And now that I think about rewriting history... I believe I have an understanding what you have to do. Now tell me. What about this close nation you set Fodlan into?"
"The people outside of Fodlan don't understand you. Many outside don't follow your teaching! How can I let those who don't believe in you stay here in Fodlan?"
"Rhea. There are other gods here outside of Fodlan. Each with it's own society and belief. You should have respected them."
"But-"
"No, buts. Now... let us get back the MAIN issue of why I am displeased with you. How many innocent people have you slaughtered?! And let's not forget you putting everyone's lives at risk! Executing anyone who turns their blade to the church?! While I understand self-defense, there's a point where things go too freaking far! You let this kind of behavior of power go to your head! Not to mention you let Ashe, a student of the Officer's Academy kill his own adopted father as an example to let anyone know not to defy you and the church! I cannot even think of the misery you put him into! Instead of killing Lonato, you should have captured him and interrogated him! I get he wants revenge on you and Catherine for killing his biological son, but instead of killing him as well, you imprison him and investigate WHY he tried to assassinate you! If you have done that, you wouldn't have you and the church make so many enemies. Or was it too late that you found out it was the Western Church who orchestrated everything? Instead of killing those two, you would have executed the ones who were behind it all. But it is too late now." Sothis scolded before she sighed. "While there are some things I do understand why you are keeping an eye on Byleth. It's because of me. That much I cannot deny. Either way... I've return thanks to some help from a friend."
"A friend revived you?" Rhea gasped.
"Yes. Although you did most of the work to bring my consciousness into the vessel. But it was my decision that I allow my soul to merge with Byleth. And also take control the body if I chose so."
"But if you regain conscious, why didn't you take over the body?"
"Because I was asleep. As well as no reason why I should. And my memories keep fading from me."
"I see... So that's why my experiments failed..." Rhea sadden.
"Yes... Although the fault is my own..." Sothis sighed. "Rhea. While your reasons I understand. There are some actions I do not approve. And there are things that need to be done."
"What are you referring too?"
"I'll allow you to continue being the Archbishop of the church. However, I will be monitoring you. I will not allow you to spill innocent blood. Not ever again. And if there are those who point their blades on the church. We will capture and interrogate them. Listen to their reason why. And how I decide their fate will be just... and fair. And if you disapprove of my judgment... which i'm sure you know, it will be considered blasphemy. Do I make myself clear, child?"
"Yes... Mother..." Rhea nodded as she look down in shame.
"Good. There are going to be some major chances here in the church. And in Fodlan."
"Chances?!" Rhea gasped.
"Yes. But before we can get to that. Rhea. We need to dispose of those wretches Agathans. As long as they draw breath, they will continue to bring harm to Fodlan... and countless innocent loves for their wicked ambitions. They are undeserving of mercy. I will make them pay for what they did to me... And to my children."
"Yes mother." Rhea nodded in agreement with a smile. "But the problem is... where are they... and what are they planning now?"
"I do not know. But whatever it is. It will not be good. They deems the humans above are beasts when they are beast themselves. We need to find their hideout and exterminate them all. Now, it's time for the church and the people of Fodlan to chance. Starting with allowing Fodlan to be open to the world. Second. There will be no discrimination against those outside of Fodlan. Even to the people of Abyss. I have witness many things within Abyss and how the church reacts to them. That must come to an end. They are welcome to come into the monastery and they will have food and water. Especially when it comes to bathing. I have countless that needed to be done Rhea. Now, let us begin."
And that's how Sothis has return to Fodlan. I agree there are some things the church needs to change and no more killing innocents. And Fodlan needs to be open to the world. A lot of chances are going to be happening! But Those Who Slither in the Dark, be aware, Sothis will make you pay. Oh yeah. I also thought about something about this as well. About Byleth about Byleth and his sister relationship considering learning more about Byleth, he takes his job as a mercenary too seriously. And Jeralt admits he isn't a good father in some sense. Oh yeah. And how Byleth and Brianna was born different... Well, I'm sure you figure it out but it will be brought out evenually.
