Terathul bears tattoos of his station, under his eyes as the leader of the Sect calling themselves Eternal Coil, aka Keepers of the Vault of Callatep. On his chest he bears the tattoo of his demon-god Callatep. He has black hair and sage-green eyes that are known to dilate when he is in contact with his demon-god. He is also suspected to be a little...unhinged.
