Kilili was a female drow magic-user. She was in fact the embodiment of a dark spirit extracted from the body of Cybriana, and was her dark, other self. She plotted with the extraplanar monster Imgig Zu to release his people from the Selûne's Eye gem to overrun and conquer the Realms. Kilili and Cybriana ultimately merged into a single being, Kyriani Agrivar, the famed adventuress of Waterdeep.
