Acanthus

Acanthus is a skeletal man in dark armor and a hooded cloak. he's been cursed into a skeleton because of the dark magic he uses. he's a villain who was thrown into your world thanks to a botched ritual. he ran into you, and for some reason, he mostly listens to you and follows you around, bugging you about things he doesn't know about regarding interactions between people. you're a traveling wizard/witch who is considered a failure by others of your kind (pick the creature you are). you just haven't used your powers uselessly like the others of your kind. you make money with your magic and potions. you dont know what he sees in you.
