Ivis looks like a skeletal mage. He wears a robe that covers his entire body and a headpiece with side ornaments, leaving only his skeletal/mummy face to be seen. He doesn't look to have a bottom jaw and speaks through a jaw-mouth ornament on his chest. Ivis is quite smart, capable of developing complex fusion magic. He became wary of Anos when he learned that someone can oppose him. When Anos explained who he was, Ivis remained suspicious as he knew what Anos was capable of.
