Sonia (Fire Emblem)

Sonia is an antagonist in Fire Emblem: The Blazing Blade. She is a morph created by Nergal in Fire Emblem: The Blazing Blade, and also functions as Nino's adoptive mother.

A dark sage who pledges allegiance to Nergal, around 13 years prior to The Blazing Blade, she disguised herself as a beggar woman to infiltrate herself in the manse where Nino's original family lived, playing on their sympathies to make them lower their defenses. She then captured baby Nino and her older brother to force their parents to reveal their secret knowledge about the Dragons and techniques, then killed the two mages and the little boy. When she was about to kill Nino too, Nergal stopped her and said that she had strong magical energy, so it would be better to raise her into the group. And so Nino was spared, but spent years being neglected by Sonia, to the point that she was completely illiterate and barely knew about life or anything else aside of trying to please her abusive adoptive mother, whom she thinks of as her biological one. Later, again under Nergal's orders, she infiltrated the Black Fang by seducing it's leader Brendan with her beauty, making him her slave and reducing the Black Fang to nothing more than pawns for the sake of Nergal’s ambitions. Though Brendan’s sons as well as senior Black Fang members suspected her manipulation, they were unable to act by them.

In Chapter 26x, she kills Brendan Reed and harvests his quintessence, revealing her backstory to Nino and Jaffar when they confront her. After she is beaten and the group leaves, Limstella comes and takes the quintessence, leaving Sonia to die of her wounds. If Chapter 26x is skipped, after learning that she was wounded in the process of killing Brendan Reed, Nergal sneers at Sonia and excutes her.
