The Demon Princess Teratashia is a huge, female-headed cockroach with a feral visage wearing a necklace of human skulls. The necklace is a powerful magic item, but it functions at full effect only for Teratashia. The demon princess’s dark palace in the depths of the Abyss is a nexus of countless gaps between dimensions, a warren of tunnels that worm their way deep into a multitude of other realities. She is known in some circles as the Mistress of Dimensions. From the center of this network of connections, Teratashia sends her minions creeping and slithering through the planes of existence to do her bidding.

Teratashia seldom involves herself in the quarrels of the other great demons. She is far more interested in controlling the nooks and crannies between dimensions than with her political status in the Abyss. She is inclined to leave the other demon princes alone to the same degree that they also extend that courtesy to her.
