From Gekkeiju Online

Illth, The Demon Goddess of Scorpions is one of the Godly beings that wasn't created by Xalem. She is a powerful demonic being that invaded the realm of Gods from another plane. Her power is nearly equal to that of Xalem, yet she's far from a good being. She enjoys nothing more than seeing mortals suffer.

She's known to command a huge army of Scorpion Demons who some foolish mortals have tried to summon into the realm of mortals every now and then.
