Shadow

Shadow (AKA Violet) is my "self insert" as well as a character all on her own. She is the very first character I ever created, going through many changes over the years. (not displayed here)

She is a Shadow Demon. When a creature dies a shadow is left behind, and depending on the circumstances magic can be left to wander in the spirit realm. When this happens the shadow of that person will attach itself to the magic to form a physical body. This can only happen with demonic magic.
