Leech

The Leech is one of a number of godlike entities called Conceptuals. While gods are created based on the needs of mortals, Conceptuals are created based on the needs of the multiverse itself, and usually represent abstract ideas or physical laws. The Leech represents entropy, and her titles include "The Third Axis," "The Bulwark Against the Void," and others.

Unlike other Conceptuals, the Leech became fond of dealing with mortals. Her favored form was a small girl with porcelain-white skin, a black dress, and unnaturally large blue eyes. Her throat was lined with concentric rings of sharp teeth. Her true form may have been impossible for mortals to discern, but on occasion she took the shape of black tendrils, vertebrae, and an ocean of scaly black reptilian skin. Mortals with whom she dealt include Mylepha Illoquen, Silifrey Woods, and Migueston Invictus, and she was known to grant boons to those who did their part to forestall the end of the multiverse.

She was destroyed in the ruins of T'sentri when Mylepha absorbed her power, effectively becoming the new Leech.
