Ardere

Ardere is a Revenant. a Revenant is a human soul that was killed in a terrible way, and has come back from the dead in the form of a terrifying demon to take revenge on their murderers. they are driven by anger, and that same anger is what keeps them tied to this world. Ardere was accused of being a witch at a young age, and was burned alive. she came back as a demon and burned down the entire town, getting her revenge. Because she got her revenge, most of her anger is gone, and she has reverted to a less terrifying form. each Revenant has a "weapon of choice" that they use to take this revenge. Ardere's "weapon" is her ability to catch her entire body on fire at will. her skin is incredibly hot, and will burn anything it touches, so she has to wear fire proof gloves to protect the people around her, and wears flame retardant clothing. she stays away from people so she doesn't accidentally burn them. since she's a Revenant, she still has a little bit of anger, but is mostly very sweet.
