A/N: I want to take a moment to apologize for not updating sooner. I'm not abandoning my stories. It's just that life has been pretty weird. I am also working on two other stories, maybe even more. Also, I realized that I didn't include Neo, and I have no clue why, and I apologize for that. Now, I will stop taking up your time, with my rants, so you can read chapter three. I hope you enjoy this chapter.

Ruby's Pov:

I woke up to the sound of loud barks and wet dog kisses. I got up kind of groggily, not wanting to wake up from my wonderful dreams of eating strawberries and cookies, while slaying Grimm with my precious Crescent Rose. Once I was able to open my eyes, I look around my surrounding and my heart immediately drops. I guess it wasn't a nightmare. I'm really stuck...here? I don't even know where here is.

Zwei is barking trying to grab my attention. "Huh? What is it boy?"

Zwei paws at the door. He probably wants to go take care of business. I take a deep breath and jump off my bed. I miss jumping from my old bunk bed in Beacon. I open the door for Zwei and we head downstairs. I open the front door for Zwei as he barks in appreciation. I lean against the door frame, thinking about how we are gonna get out of here.

Lost in thought, I jumped up in shock when Toriel placed her hand on my shoulder. "I apologize, my child. Are you and Zwei hungry?"

I would have declined but my stomach growled. I blushed and responded, "Yeah, food would be great. Don't you agree Zwei?"

Zwei barked his agreement. We ate our breakfast in relative silence, Toriel would occasional share snail facts. Once Toriel finished, she took our plates and went to wash them. I was staring at my glass of milk, debating if I should ask the inevitable question. "Um, Toriel... I miss my family and I wanna go back to Beacon. Do you know how I can get out of these ruins and return home?"

Toriel's mood changed from one of happiness to a more somber one, "... I have to do something. Stay here."

Toriel stopped what she was doing and quickly left. I'm not sure if I should follow her, but one look at Zwei, and I pick him up and run after her. Once we find her, Toriel her back is turned to us. I reach a hand to her and she turns around slowly. I stop and see a few tears fall from her face. She has a small sad smile and tells Zwei and me, "You wish to know how to return "home," do you not?"

Not noticing the emphasis she placed on home, I nod my head, "Yeah, I really want to return to my family."

Toriel swallows a lump in her throat and continues, "Ahead of lies the end of the RUINS. A one-way exit to the rest of the underground. I am going to destroy it. No one will ever be able to escape again. Now be a good child and head back upstairs." As she says this, she turns away from me and walks ahead.

I am beyond shock, "Wait, what!? You can't do that." I can feel the tears wanting to escape, Zwei licks my face to comfort me. I look down at him and nod my head in determination. Crying never solved anything. I have to stop her, so me and Zwei can go home to our family.

I ran after Toriel again, easily catching up to her. I grab her arm stopping her from proceeding further. I can see the light of the exit in front of us. "Toriel, please don't do this! I need to return to my family! I don't belong here!"

"I apologize, my child, but it must be done..."

"But why!?"

"Every human that falls down here meets the same fate. I have seen it again and again. They come. They leave. They die. You naive child... If you leave the RUINS... They... ASGORE... Will kill you. I am only protecting you, do you understand?...go to your room. This is your final warning," Toriel says, without looking at me.

I let go of my grip on her arm, "I'm sorry Toriel, but I can't do that. That's not my room. I don't belong here. I understand you want to protect me...but I'm a huntress-in-training, trained to kill monsters. I can protect myself...I'm sorry, but I am going home."

"You want to leave so badly? Hmph. You are just like the others. There is only one solution to this. Prove yourself...Prove to me you are strong enough to survive."

"There's gotta be another way..."

"Unfortunately, there is none," with a wave her hand, Toriel sent a volley of fireballs at me. Fortunately, I was able to dodge all the fireballs while carrying Zwei with me. This reminded me of the training I did with Yang. However, I knew I wouldn't be able to attack her without my precious Crescent Rose. I wasn't very good at close combat.

"Zwei go find somewhere safe to hide," I commanded my corgi, placing him on the ground. I have no idea how I will win this fight.

Normal Pov:

Toriel watched as Zwei obeyed his mistress, although he did so with some hesitation. Toriel remained aloof, and waited for the dog to move out of the way before using her magic to send more fireballs at Ruby.

Ruby was able to doge most of the fireballs, due to her training at Beacon. However, she wasn't able to dodge all the fireballs. Fortunately, Ruby's aura protected her from having great damage and burns. Using her semblance, Ruby was able to get close enough to Toriel to roundhouse kick Toriel's face.

Toriel tumbled back, holding her cheek. Toriel quickly prepares to use her magic and keep Ruby away from her. Ruby continues using her semblance to try to approach Toriel as close as possible, while avoiding most of the fire spells. However it becomes increasingly difficult, because Ruby's aura was quickly depleting. It also appears as though Ruby did not cause much damage to Toriel.

As for Toriel, she wants to hold back, but Ruby proves herself to be a decent opponent. Although, Ruby has a quite a ways to go if she wants to escape the underground. Toriel can tell that the small red clad child was becoming tired, and would eventually have to admit defeat and stay with Toriel forever.

Close combat seemed to be useless in Ruby's case, seeing as she wasn't causing much damage to Toriel and she was low in aura. Ruby decided to keep her distance and try a new tactic. A tactic that Toriel recommended, Ruby would try to have a conversation with her. Rolling away from several fireballs, Ruby begins, "Toriel...Please! Please...stop this. We don't have to fight."

Toriel remained aloof and continued her magic attacks. Ruby thought momentarily about giving up, but shook that thought from her mind. Ruby Rose is not one to give up so easily, not without a fight. She had to return to her friends, no to her family.

Ruby was unsure as to how she would persuade Toriel to stop fighting and make her understand that she had to return home. She opted she would try using her semblance once again, in hopes of being close enough that she could look Toriel in the eyes, so Toriel can see the raw emotions of determination, passion, and desperation, that or convince Toriel to let her go with her puppy dog eyes.

With a burst of speed, Ruby made her attempt. Unfortunately, Toriel sent a ginormous fireball close to Ruby, which sent her skidding across the floor from the force. Ruby slowly got up clutching her left side, her clothes were practically ruined and her body was covered with bruises and scrapes.

Toriel lost her aloof nature momentarily, feeling worry and pity for the child. Toriel could not comprehend why this child would not give up, why did she want to leave Toriel so desperately. The thought of Ruby leaving Toriel, like the other children before her, brought sadness into her heart, and a single tear fell from Toriel's face.

"I know you want to go home, but why...why do you want to leave so desperately, my child? What are you trying to prove? Do you not realize you are safe here, that you will die if you leave me? I promise to protect you," Toriel sobbed out, flames appearing behind her, burning in with the intensity she felt within.

Ruby looked deep into Toriel's eyes, "My family is waiting for me and Zwei. I have a responsibility back on Beacon. I am the leader of team RWBY, they need me and I need them. I can't be their leader if I'm stuck here."

The intense staring contest between the two continued for a few short moments, but it felt like an eternity to them both. Ruby was starting to feel uncomfortable with the intensity, but she refused to back down. Ruby finally broke eye contact, when she felt something wet and slightly cold lick her hand. She looked down and Zwei was staring at Ruby. Ruby shook her head slightly while smiling, picked up the corgi in her arms.

Toriel watched the red-cloaked girl and her dog's interaction silently. When they both looked back at her, Toriel let out a sigh and the flames around her slowly faded away. Tears steadily began to flow from her face to the ground, "I know we don't have much here, but we can have a good life here," a despondent smile graced her features, "Why are you making this difficult?"

Discombobulated, Ruby was unsure how to respond to the question and was uncertain how to react in this situation with the goat humanoid. Therefore, she opted to remain silent, holding Zwei tightly to her chest, uncertainty and suspicion riddling her facial features.

"Pathetic, is it not? I cannot even save a single child..." The tears were cascading down Toriel's face, Ruby was confused and she could see Zwei tilt his head in confusion as well.

"No, I understand. You wouldn't be happy stuck down here. The RUINS are very small once you get used tom. It would not be right for you to grow up in a place like this. My Expectation... My loneliness... My fear... For you, my child... I will put them aside for you are...special."

"Uh...thank you?" Ruby was totally confused.

Toriel solemnly giggled, "If you truly wish to leave the RUINS...I will not stop you. But first, would you allow me tend to your wounds and mend your clothing?"

"Oh yeah! I would really like that." Ruby was rubbing her head in embarrassment, while smiling. Zwei jumped from Ruby's arms and barked his agreement.

The trio made their way back to Toriel's home. Once inside, Toriel gave Ruby a red and black striped sweater and a pair of shorts to change into and then began to place bandages on some of Ruby's wounds, but she noticed that some of them were healing slowly.

"Well that's peculiar..."

"Huh? What's peculiar?"

"Well, my child, I noticed that you don't have as wounded as I originally thought and some of your wounds are already healing."

"Oh that's because of my aura."

"Aura?"

"You don't know what aura is?"

"I'm afraid not, my child."

While Toriel continued to tend to her wounds, Ruby proceeded to explain about aura and semblances. She even told Toriel about each of her friends' semblances. Once that was done, Toriel went to look for thread to fix Ruby's clothes. Unfortunately, she could not find any.

"I am sorry, my child, but I am unable to find any thread. I won't be able to mend your clothing," Toriel bowed her head in apology and embarrassment, for she was the one to ruin Ruby's clothes.

"It's okay. Our fight was pretty intense, so don't sweat it."

"Your are too kind, my child. If you would like, why don't you keep the clothes that I just gave you. They seem to fit you well and I have no use for them." Ruby accepted the offer. Toriel gave Ruby her tattered clothes. Ruby decided to keep the tights and her signature red hood, and discarded the rest of her outfit.

Toriel offered Zwei and Ruby lunch, which they accepted. They ate in silence, knowing that they will be parting ways soon.

After lunch, Toriel led Ruby and Zwei towards the RUINS' exit. At the door, she turned around and tried hard not to let the tears fall as she hugged Ruby. Ruby was a bit surprised from the hug, nevertheless Ruby reciprocated the action.

"When you leave...Please do not come back. I hope you understand."

Toriel let go of Ruby and patted Zwei's head before slowly walking away, looking down at the ground. "Wait," Ruby shouted, grabbing Toriel's arm. They stared in each other's eyes, and they could see the tears threatening to fall from their eyes. "Thank you for everything."

Toriel smiled solemnly, "No, thank you. Farewell, my child, Zwei."

Ruby nodded her head in affirmation and started head towards the door leading to the exit. She stopped at the edge of exit and took a deep breathe. Looking down at Zwei, who was looking back at his master while wagging his tail in anticipation. "This is it Zwei. No turning back now. Time for us to start our journey back home."

Zwei barked his agreement. They opened the door and walked down a long hallway. The pair eventually encountered Flowey. Ruby got in a fighting position that Yang taught her, and Zwei growled at the flower.

"Clever. Verrryyy clever. You think you're really smart, don't you? In this world it's kill or be killed. So you were able to play by your own rules. You spared the life a single person. heheheeehee. I bet you feel really great. You didn't kill anyone this time. But what will you do when you meet a relentless killer? You'll die and you'll die and you'll die. Until you tire of dying. What will you do then? Will you kill out of frustration? Or will you give up entirely on this world...and let ME inherit the power to control it? I am the prince of this world's future. Don't worry, my little monarch, my plan isn't regicide. This is SO much more interesting," Flowey laughed evilly.

Ruby had a few words to share with Flowey, but he disappeared into the ground before she had a chance to say anything. Ruby unclenched her fist and took a deep breathe. She wasn't gonna let what a creepy flower said waiver her resolve. She looked to Zwei and he looked just as determine as Ruby. They both moved forwards.

At Beacon Academy:

Weiss was sitting on her bed, watching Yang pace all around their room. She could see how distraught and furious her friend was. Occasionally, Yang's eyes would flicker from lavender to red.

"I can't take it anymore," Yang finally screamed. She proceeded to stomp out of the room.

Weiss, worried, decided to follow Yang. "And where do you think you're going?"

"I'm gonna get some answers and find my baby sister." Everybody moved out of Yang's way, no one wanted to experience the blonde beauty's fury, especially right now.

"And how do expect to do that? Roman is under General Ironwood's custody and I highly doubt that he'll allow us to question him."

"I'll think of something."

"Yang you need to calm down and think about this logically."

"I don't have time to calm down and think about this. I gotta find Ruby. She's somewhere in a Grimm infested mountain without her weapon...all alone...unprotected...I-I failed as her older sister." Yang fell to her knees, covering her face with her hands as some tears fell.

Weiss knelt down next to Yang, placing a comforting hand on her shoulder. "I know. I failed her as a teammate...as a friend. I promised to be the best teammate...and I failed...I let her down." Now tears were falling down Weiss's face.

"I'm sorry to interrupt, but I need to speak to both of you in my office," a new voice said. Both girls turned to see Professor Ozpin standing in front of them, with a cup of coffee in his hands. He looked at the girls with sympathy, knowing how it feels to lose someone you love. He handed the girls each a handkerchief. "It concerns the disappearance of Miss Rose."

Both the girls quickly got up, asking the headmaster if he had any news to share about Ruby. "All will be revealed in due time. You wouldn't happen to know where I might find Miss Belladonna, would you?"

Yang growled softly, when she heard Blake's name. Yang was extremely pissed off at Blake. During the ride in the bullhead, they did not utter a single word, but Yang glared holes into the back of Blake's head.

"I'm sorry Professor, but we haven't seen her since we arrived at Beacon," Weiss replied. Weiss looked to the ground, she was also extremely upset with the cat faunas.

"Well that's unfortunate, but I'm sure Miss Belladonna will appear soon."

"For her safety, I hope not," Yang muttered under her breathe.

"I beg your pardon Miss Xiao Long, I didn't quiet hear you."

"Nothing! I said..nothing."

"Very well. Shall we carry on then."

"Of course, Professor," both girls replied.

The walk to Ozpin's office was silent. Weiss would occasionally to take a glance at her partner's sister to see that Yang kept her gaze solely on the ground, with her hands clenched tightly and her bangs covering her eyes.

Once they arrived at Ozpin's office, the pair were shocked to see team JNPR already waiting there. They thought team JNPR were supposed to be well on their way for their mission in a small village.

Ozpin walked over to his chair behind his desk to take a seat. He motioned for everyone to take a seat. "You all may be wondering why I called here you here today. The reason being..."

Ozpin was interrupted mid-sentence when the door opened. Everyone turned their heads to see Glynda and Blake walk inside the office. Blake was trying her best to avoid everyone's stare, but couldn't help looking up towards where she felt Yang's heated glare.

Ozpin cleared his throat to gain everyone's attention. "Thank you for finding Miss Belladonna, Ms. Goodwitch. You are excused. Miss Belladonna, please a seat. Now back to what I was saying. Have any of you heard of the story about Mount Ebott?"

The teens turned to each other in confusion, they never heard of such a place. Pyrrha was the one to speak, "I'm sorry Professor, but I don't think we have."

"I'm not surprised. The legend of Mount Ebott has been written off as a fairy tale and throughout the years has slowly faded..."

Yang abruptly got up, slamming her hands on Ozpin's desk. "What the hell does this have to do with Ruby!?"

All of the teens stared at Yang with mixed emotions, not sure what to do.

"Miss Xiao Long, I assure you this has everything to do with Miss Rose."

"Are you sure, because it sounds like you're just telling us about some bullshit fairy tale when we should be searching for MY SISTER." Everyone cast their eyes away from Yang, except Ozpin who stared at Yang with steely eyes. The headmaster realized that the blonde brawler was extremely worried about her younger sister, but her actions and emotions were getting out of control. Just the other day, he received several complaints that Miss Xiao Long had destroyed some school property and gave death threats to those who would talk behind her back about team RWBY.

The tension in the air was suffocating. Time seem to slow down as neither the headmaster nor Yang would back down from the staring contest. Ozpin calmly closed his eyes and sighed. He would have spoken, but a certain cat faunus beat him to the punch. "Yang...I know you're upset, but you can't keep doing...this. You need to control your ang-"

"Shut up! You don't know about anything! Everyone keeps saying they know how I feel...but you don't...You didn't lose a sister...you don't even care that Ruby's missing. You just hid in the shadows...just like you always do." Yang was crying at this point.

"You're wrong! You're wrong...we do care because...we lost a sister too. We understand your feelings, but we're not letting our emotions get in the way. Losing control of our emotions will only make it harder to find Ruby." Blake got up and approached her partner. "Yang...I'm sorry for being a...coward and not looking more concerned when Ruby went missing...I should have defended you and Weiss...I should have searched for Ruby..."

"W-why didn't you?" Yang wiped her eyes with her hands.

"I thought that once we had Roman...he could tell us about what the White Fang were planning. Then we could question him about Ruby. I lost track of what's important. I realized how stupid I was being once we got inside the bullhead. I was wrong to leave Ruby behind, and that is something that is unforgivable...but I want to fix my mistakes. I want to find Ruby, no matter what it takes."

Yang pulled the cat faunus into a hug, which Blake reciprocated.

"I too want to find Ruby, no matter the cost," Weiss seconded rising up from her seat and approaching the two girls. Yang pulled her into the hug as well.

"I think I speak for all of us when I say that we all are willing to find Ruby, no matter what," Jaune spoke for his team. The trio turned to see the determined look on each member of JNPR.

Ozpin cleared his throat, and all the teens gave their attention to the headmaster. "I'm glad to see how committed you all are to finding Ruby. Now, I do believe Miss Xiao Long you were questioning what significance the story of Mount Ebott has on Ruby's disappearance. Well allow me to enlighten you all. For you see, I have reason to believe that Ruby is currently somewhere in Mount Ebott...the Underground to be exact."

"So where's Mount Ebott and why haven't you found Ruby underneath the mountain yet," Jaune asked.

"Well it's not that simple, Mr. Arc."

"Excuse my forwardness,but why not Professor," Weiss asked.

"To answer your question, I must first tell you about the legend about Mount Ebott and a war that happened so long ago..."

Elsewhere on Beacon's Campus

"I can't believe that bozo ruined all of Cinder's plans, just because he couldn't take care of four stupid little girls," Emerald said allowed in annoyance to Mercury who was reading. "She shouldn't have left that idiot on his own to be in charge of such an important part of our plans. If only Cinder let that ice cream loving psychopath with Roman, then we wouldn't be in this mess."

"Careful, you don't want Neo to overhear what you're saying about that orange-haired loser," Mercury responded nonchalantly, turning a page in the comic that he stole.

"As if I care-"

"My, my Emerald. You should really be careful of what you say. You know that Neo had to take care of our...little problem," Cinder said, walking into their dorm room with Neo right behind her. Neo gave the two a death glare. Mercury and Emerald both stood up straight when they immediately saw Cinder. "I really do hope you weren't questioning my decisions...for your sake of course." Cinder approached Emerald, and held her chin in her hand.

"Of course not Cinder. I would never." Emerald looked like a frighten lamb.

Cinder chuckled in amusement. "That's a good little girl." She let go of Emerald and walked to take a seat at the desk. "Although we might be experiencing a minor setback, are plans should continue moving forward as long as the Vytal Festival is still occurring."

"Yeah that might be a slight problem," Mercury voiced.

"Do tell what this problem is."

"Well I was heard some rumors around campus that they might postpone the Vytal Festival, or cancel it all together."

"You know you shouldn't waste my time with rumors. However, if these rumors turn out to be true then it may cause us problems down the road. Did you hear why this might occur?"

"Unfortunately I did not."

"I-I did," Emerald said. Cinder motioned for her to continue. "Oh, um...apparently a student went missing during her mission and two of the teams that were going to participate in the festival are going to search for her. They say that Ozpin may send more people, but no one knows for sure."

"I wonder what's so special about this student that they're willing to cancel the Vytal Festival," Mercury asked outloud to no one in particular.

"Strange indeed. I want you three to find out more information about this little situation, while I go take care of some other business."
