Darios

Darios (ダリオス, Darius) is an original non-playable character in Fire Emblem Warriors.

Role in Game
Darios 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 when they are separated from Darios during the attack on his own kingdom Gristonne, Darios is being ambushed and captured alone, thus ended up being possessed by the dragon Velezark from behind, revealing the Fell Dragon has been working with his father, Ozosid to get Darios back by force while Velezark uses his body as his own and use the Fire Shield for their own personal use. While remained being possessed by Velezark, Darius tricks the twins to put down their swords to save Yelena and attempts to sacrifice her for a rebirth of Velezark's full physical power anyway, but Takumi predicts this might happen and saves the queen's life. However, the possessed Darius kills his own father to perform the ritual. Shortly during a battle against the heroes, Darios' normal-self began to fight Velezark from the inside for the heroes to defeat him quickly.

Once the twins beat him and to atone for his sins, Darios begs his pupils to kill him before Velezark emerged from his body, but was too late. The twins try to think of another way, just as Velezark finally emerged from Darius' body and about impale them, but Darius sacrifice his life to save the two. Before dying, Darius throws his pupils the Fire Shield as he falls into the abyss.
