Edelgard von Hresvelg

MAJOR SPOILERS FOR FIRE EMBLEM: THREE HOUSES Edelgard is a main character and the leader of the Black Eagle house in ''Fire Emblem Three Houses. ''Heir to the Adrestian Empire, Edelgard became the leader of Those Who Slither in the Dark, and under the alias of the Flame Emperor, worked to destroy the Church of Serios and start "The Great Fodlan War".

Biography
Edelgard was born in 2001 and was experimented on by Those Who Slither in the Dark. This caused her to gain the Crest of Flames and her hair to turn white. This also shortened her lifespan significantly. This changed her view of the Church and the current nobility system forever.

Knowing she had to act fast, she devised a plan with her retainer, Hubert, to pose as the Flame Emperor and craft a way to create the ideal Fodlan in the time she had left. Destroy the church and create a new nobility system without Crests.

In the year 2018, Edelgard attended Garreg Mach Monestary as the leader of the Black Eagle House. The Black Eagles were to be taught by the new recruit Byleth, who Edelgard took an interest in.

Months passed and the two grew close, Byleth seeing Edelgard as a sort of daughter figure.

The next year in the Holy Tomb, Byleth discovered Edelgard's true identity and attempted to kill her. Hubert teleported Edelgard out and Edelgard knew she could no longer trust Byleth, as much as she wanted to.

In the next month, the Imperial Army attacked Garreg Mach. The area was destroyed, Lady Rhea vanished, and Byleth was presumably dead.

During her time fighting in the war, Edelgard found time to compose a song she called The Edge of Dawn. When publishing it, she kept her identity a secret, labeling it as written by the "Lady of Hresvelg".

Around a year later, Edelgard was visited by King Dedede, who then told her that Byleth was alive and he apologized for being at fault for her death. Edelgard was left with the decision to kill Dedede after he "set things right".

Personality
Edelgard is a very serious character, always thinking about the next battle or decision. She carries this trait into conversation, with her humor being a bit dry (though having more of it than her retainer Hubert). This does not mean she lacks emotion, for she has shown concern for the lives of her fellow Black Eagles and wants them all to succeed.

A large amount of her emotion has been shown involving Byleth. She cared for Byleth the most out of everyone at Garreg Mach and was saddened with the decision to betray her. Even when on opposing sides, Edelgard was saddened over the possible death of her mentor.

Entering the war, Edelgard lost most of her humanity, devoting herself fully to taking over and ruling Fodlan with the little time she had left. She only had five years and aimed to make them count. She rarely let anything sway her from her chosen path.
