Elsa is a mad pyrokineticist.
The Dark Inquisition was about to public burn Elsa and her friends for white sorcery. That's when her abilities revealed. From all who were on the execution, only she survived.
Since then she walks through the world, lunatic and unaware, turning people and things she touches to ashes. She believes that she makes them free that way.

She is a pyro of my team RED. (yeah, I have a TF-inspired team of characters) Everyone in team are afraid of her (except of the Scout who has a unique ability to face Elsa towards enemies).

(Also if you'd like to get a sketch like this, check my commissions :D )
