So if anyone actually read Claire's ref then they'll have read that she's a weredemon and I finally got arround to finish the ref of her demon form.
She aquired this form due to a botched demon summoning where she should have been the sacrifice but because she studied magic herself she managed to screw the spell cyrcle up enough to where the ritusl would not cost her life. But not enough to spare her completly. Instead of the spell costing her life it killed the summoned demon and tranfered it's energy into her body. So ever since that day she can turn into this thing and all she does is terrify children for fun. Also every new moon she is forced to take on this form just like a werewolf at the full moon.
