Hello, FE readers! This is an idea that occurred to me... I think it was on either Robin's, Validar's or Plegia's page in the Fire Emblem Wiki, that said somethin' like "Because Validar is dead, Robin is technically ruler of Plegia. This is not mentioned in the game, however." So I thought, "Hey... Yeeeaah..." AND SO THIS! Yeah, I find it entertaining that Robin's ruler of a nation they considered the enemy for two years, sooo... Enjoy the story!
P.S. This chapter is just a prologue because, as the title states, it is the game's final chapter and not a chapter written originally by me, so it doesn't really count.
P.S.S. Fact: I hate referring to the tactician as "the Avatar." It's either "Robin" or the name the player chose for them. "The Avatar's" just so... plain... and dull... You know?

Prologue: Endgame

"Hear my words, Awakener!" said the celestial voice of the Divine Dragon, Naga. The Ylissean League, as the Shepherds had been known as after becoming a much larger group, were ending yet another war in a final battle against the Grimleal and the Fell Dragon himself, Grima. After Robin refused to give himself up to bring Grima back to the world, Plegia's "hierophant," later revealed to be Robin's future self, took matters in his own hands and became one with the Fell Dragon. "Grima's servants will beset you to no end. Dispatch him as soon as you are able!" Chrom, leader of the Shepherds, and Robin, tactician and grandmaster of the Shepherds, looked at each other and nodded. When the two heard Naga's voice, Chrom told his wife and queen of Ylisse, Sumia, and his daughter from the future and princess of Ylisse, Lucina, to continue the battle with the others while he and the tactician heard what Naga had to say. "Once the fell one is weakened, a choice will await you... If Chrom lets fall the final blow, Grima shall survive but return to his slumber..." Knowing he'd need strength for the battle, Chrom went to Mount Prism so the Divine Dragon would transfer her power to him. However, Naga revealed she is not a goddess, and that Grima is not a god. However, she was able to unlock the Falchion's true potential, which was now able to send Grima into a deep slumber.

"So be it," said Chrom, who previously tried to prove his point to Robin on why he should take down the Fell Dragon. He must understand, thought Chrom, He must understand how important he is to us. To all of us! ...To me. I see no point in fighting such a beast only to lose a friend.

Naga then continued. "If Robin strikes in Chrom's stead, both his life and Grima's are forever over. Only in this way may the fell dragon be destroyed for good and all."

"..." Robin did not want to die, but he knew this was right. Why lose millions of lives if my sacrifice will lose just one? He struggled to understand why Chrom wouldn't let him, Why trouble future generations when I can finish this now, for everyone! I love him as a brother. I love them all. And... Lucina... Morgan... But he-they must understand.

"The final decision... is yours." After that, Naga's voice was not heard.

"CHROM!"

"What is it, Sumia?" asked Chrom, looking up to see his wife and daughter, Cynthia, on their pegasi dodging arrows. "Damn! Someone kill those ar-"

"Forget me, Chrom! It's Grima!" said Sumia. Chrom and Robin looked over to where Grima was. They saw Grima himself attacking their allies. Right now he was focused on Vaike, who thought he was though enough to take down the dragon.

"HA! A big ol' dragon can't take down the Vaike! Now let Teach give ya a li'l les- OOF!" Vaike was attacked by Grima's Expiration, and was sent flying right into an ongoing fight between the sage Lissa and a Grimleal member.

"AH!" The tomboyish-princess was startled. "Vaike, you idiot! Just what do you think you're- Oh gods!" She rapidly got her Mend Staff, then turned to her family, Owain and Henry. "Guys! Cover me while I Mend Vaike!"

"Why of course, dear mother!" answered Owain, while slashing down another Grimleal.

"Nyahaha! You got it!" shouted Henry, while casting Nosferatu. "Yeah, blood!"

Chrom was relieved to see his sister still okay, but still had to save his wife and daughter. He then turned towards one of the archers, who had a Longbow. He ran towards him, then slashed him with the Falchion. Another archer was taken down by Robin with a Thoron tome, which then closed and turned to ash. He swiftly grabbed a Bolganone tome from his cloak. Lucina stabbed her Falchion into another archer.

"Now that that's been taken care of..." muttered Robin, "Chrom, Lucina!" The king and princess looked at their tactician, who was also his son-in-law and her husband. "We have to finish this! We have to take down Grima now!" Chrom and Lucina nodded at each other and ran towards the Fell Dragon with Robin. Morgan noticed her parents and grandfather run towards her alternate-future-evil father, and decided to follow them as well, with Sumia and Cynthia flying towards their enemy as well. Robin cast Bolganone at his future self, who dodged the attack.

Grima chuckled to himself in a sinister manner. "...RETURN TO ME... COME... WE ARE ONE...AND THE SAME..." he told Robin, who just scowled at his evil self. He pointed at Robin, and Grima shot Expiration at him. Sumia saw this and swiftly swooped down towards Robin, picking him up and flying out of the attack's range.

"Thanks," said Robin. Sumia nodded. She flew around Grima, and Robin cast Bolganone at him again. This time, because the "hierophant" was distracted attacking Chrom and Lucina, the attack hit. Using the chance, Chrom and Lucina used their dual strike, spinning their swords and rushing towards Grima at light-speed, creating an "X" form. Cynthia then dived in at Grima and attacked him with her Brave Lance with a stab, and then another. Green slime then appeared around him, and then damaged him. Robin turned towards Henry, who was laughing like a maniac while his wife and son struck down enemies who closed in on him. The grandmaster also saw enemies simply fall to the ground, dead, after a horse passed by them. Then some sunlight reflected above the horse and he realized it was the great knight Kellam killing the Grimleal. He turned to Grima. "I'm going to jump, Sumia," Robin told her.

"What? What kind of mani-" Sumia was interrupted when Robin jumped from the pegasus, Silver Sword in hand, and fell towards Grima, striking him. Grima fell to the ground on one knee, to weak to battle any longer.

"...NNGH...AAAAUGHHH..."

"Now, Robin! This is our chance! I'm going to finish it!" screamed Chrom, turning to where he last saw Robin, but noticed he wasn't there. He was standing in front of the weakened Grima, with an arm raised, casting some kind of magic. "...Robin?! Wait, what-"

"...WHAT...WHAT ARE YOU DOING?" asked Grima, in his face only pure horror.

"For once, I'm glad you and I are the same. Now I can give my life to protect those I care for..." said Robin, who turned to face Chrom, Lucina and Morgan, who were frightened knowing what he was going to do.

"...YOU WOULD...NOT DARE!" screamed Grima, even more terrified than he was before.

Robin smiled at his family. "I would and I will." He then faced his future self. "The evils you would visit on this world are unthinkable... In some way, I-we share the blame. It's only right we meet our end together!"

"Father, do something!" screamed Lucina, tears going down her cheek.

"...NOOOOOOO!" were Grima's final words before Robin's magic grew and was launched at him, resulting in his death. However, the dragon itself was still there.

"Robin! No!" screamed Chrom when he saw his best friend's body begin to fade.

Robin turned around, chuckled, and then smiled. "Thank you, Chrom. For...everything... Tell the others...my last thoughts were of them..."

"Tell them yourself, you selfish dastard!" snapped Chrom. Lucina and Morgan were hugging, crying and looking at the man one called "husband" and the other, "Father."

Robin shaked his head. "No...I can't... May we meet again, in a better life..."

Chrom began to cry. "Robin! No! Ah gods, NO!" Robin turned to face everyone. His friends, his family. A single tear fell down his cheek, and he smiled. Robin raised his hand, and waved good-bye, his body fading away.

Robin whispered to himself, "Lucina... Morgan... Never forget me... I love you..." His body was then gone.

Realizing the dragon Grima's body was soon going to dissapear, Naga teleported the Ylissean League back to Origin Peak. Chrom, Lucina, Morgan and the whole army mourned for their lost companion and friend.

And that's the end of the prologue! The game's events afterwards (Chrom and Lissa finding Robin again) will be written in Chapter 1. So I hope you're interested in the plot and my style of writing and that you'll review, favorite and continue reading!
