The World of Fire Emblem. For generations upon generations, armies have risen against the darkness and brought peace to the lands. From Altea, to Ylisse and Valm, and to Hoshido and Nohr, these kingdoms have all persevered against the darkness and brought peace to their lands. In all the generations of these kingdoms, they have never crossed paths. This time, they will, when a new kingdom comes under the fall of darkness.

In a far away land, beyond the confines of the generational kingdoms, lies the Kingdom of Aytolis, a kingdom living in peaceful times. Its ruling family consisted of a queen and her twin children: one boy and one girl. Both of which have equal right to rule the throne of Aytolis when their time comes. Their names are Rowan and Lianna, and both, while twins, have no desire to rule the throne.

"Let Lianna take the throne. I'm gonna be Aytolis's most powerful knight!" said a young boy with blond hair.

Twin Prince of Aytolis

Lord

Rowan

"Well, I don't want it either! You can be a knight and a king." said a girl with blond hair.

Twin Princess of Aytolis

Lord

Lianna

The two of them were arguing.

"And again with the bickering. You two stand at the grasp of adulthood. What would he think of...if your father was alive to see this." said a woman with long blond hair.

Queen of Aytolis

Yelena

"Prince Darios of Gristonne has arrived!" a guard called out.

"Darios is here?! All right!" Rowan said as he ran.

"Hey, wait! Rowan! No sparring today! He already promised he'd help me with my studies! Are you listening?!" Lianna asked as she went after him as the queen sighed.

It was then that the two of them were at the courtyard where Rowan was having a swordfight with a young man with black hair.

"I'm gonna beat you again, Darios!" Rowan said.

"I'd like to see you try." Darios said as he and Rowan clashed before Rowan was knocked flat on his back.

"You say you're gonna beat him again but Darios has never lost to you to begin with." Lianna said.

"Now then, let's see what Lianna can do. If you meant to sit and watch, you are very much mistaken." Darios said.

Prince of Gristonne

Lord

Darios

"I don't normally wield a sword when I'm so outmatched. But if it means I'll get better, then… I'm happy to oblige." Lianna said.

"You know what is ideal. Strength and wisdom alike. Both in equal measure." Darios said.

But before they could fight, a crash in the sky was heard as a rift of darkness opened in the sky as falling from it were strange monsters that were invading the kingdom.

"What're those things?" Rowan asked.

"They're going for…" Lianna said.

"...the throne room!" Rowan said.

"If she's up there, then…!" Lianna said.

"Mother's in danger!" Rowan said.

"Leave your mother's safety to me. You two must escape!" Darios said.

"No, I'm going with you!" Rowan said.

"You can't! The enemy is already inside the castle. If you're captured, then…" Darios said.

"Your highnesses! It is not safe here! We must make way to the secret passage!" a soldier said. "Your mother is already on route."

"Then there's no time to waste. Let's hurry to join her." Lianna said.

"We're coming Mother." Rowan said.

The three of them ran into the castle that was filled with monsters. "Remember your training. Cut them down like mere blades of grass!" Darios said.

"Yeah!" Rowan said showing no fear as he swung his sword and cut the monsters down. "C'mon, Lianna!"

"Rowan, not too fast! I'm not as skilled as you are!" Lianna said as she parried a few before tripping up and falling over as a large monster glared at her. "Ah...Aaaaah!"

"Lianna!" Rowen called.

As the monster was about to attack, something then came out of nowhere and hit it right in the face so hard it was sent flying into the wall on the other side.

"Wha…?" Lianna asked as she was staring at an unfamiliar black suited man with blond hair.

"Are you alright, my princess? Your handsome knight is here to protect you." he said.

"Who are you?" Rowan asked.

"My name is Sanji, but to the lady, you can just call me Mr. Prince." Sanji said striking away at the incoming monsters.

"I've never seen kick strikes like that… who is he?" Darios asked.

"He's not from Aytolis, I can tell by his attire…" Lianna said.

"Hey, Sanji! Are you gonna flirt with the princess all day, or you gonna get her and her twin brother over here!" a girl's voice called from down the hall.

"Coming!" Sanji said as they hurried down the halls to where the queen and her soldiers waited.

"Mother! Are you alright?" Rowan asked.

"Yes! I'm so glad to see you two safe as well." Yelena said. "Thank you so much, Prince Darios."

"Let us not waste time. Our enemies will more likely pursue us. We must go!" Darios said as they hurried down the tunnel before the ceiling collapsed, separating the twins and Darios from the queen.

"Mother! Are you okay?!" Rowan asked.

"Yes, but I can't get through. You two will have to go on without me." Yelena said.

"No, we can't!" Lianna said.

Yelena gave them a sort of shield.

"Take this shield, and hurry to the temple." Yelena said.

"Mother, we can't just leave you behind!" Lianna said.

"There isn't time to argue about this!" Yelena said. "Prince Darios… Please watch over my children."

"Of course, your majesty." Darios said as they continued on, while looking on as Yelena was buried under the rubble.

"Mother, noooo!" Lianna and Rowan screamed.

Sanji couldn't help but watch from a way as he saw this sad scene. "Poor kids…" Sanji said. "Let's get goin."

"Where are you taking us, Mr. Prince?" Lianna asked.

"Out of this city before it's completely overrun." Sanji said.

"That certainly would be the best desicion." Darios said.

"Then let's get going." Sanji said.
