Acedia

"Hindsight is cringe if you don't even know what you're doing at every single given moment."

Created as a secret weapon a Nature Prince, Acedia is the best artificial human a fairy can make. She is also absolutely insane. Her skin is lightly tanned, her hair is jet black, her eyes are purple, and she wears oddly revealing clothing consisting of mostly leather. Her belly button is replaced with an ouroboros symbol, and her heart is replaced with a Philosopher's Stone. She is a powerful conduit of magical energy, impossible to kill through any means other than direct damage, and no, she does not have reproductive parts. Her mind is shielded from any manipulation, because of the insanity, she cannot be poisoned, she is immune to disease, her energy is limitless and cannot be drained, and she does not have a soul. While she isn't a trained mage, she does have powers that can be construed as spells. Her personal forbidden magic allows her unconditional teleportation, of herself or others.
