Darios

Darius is the deuteragonist and a non-playable character in Fire Emblem Warriors.

Role in Game
Darius is the one who taught Rowan how to fight and Lianna in academic arts.

At the beginning, he spars with Rowan and beats him just as the Gates of the Other World open without warning. He teams with Rowan and Lianna to fight the monsters. While escaping with the Aytolis royal family, Yelena is separated giving the Fire Shield to her children. As a result of this, Darius stays with the two as a mentor to find the other heroes.

What the heroes don't realize until later is that Darius has been brainwashed by the dragon Evil Zaag and is working with his father, Ozosid to get the Fire Shield for their own personal use. He attempts to sacrifice Yelena for Evil Zaag's rebirth but Takumi saves her. However, Darius kills his own father to perform the ritual.

Once the twins beat him and to atone for his sins, Darius begs his pupils to kill him. The two try to think of another way, when Evil Zaag appears and impales Darius. Before dying, Darius throws his pupils the Fire Shield as he falls into an abyss.
