Sencia is a servile located in Vakkiri. She is tasked by Ellhrah with looking after some of the more weak-minded serviles in her village. She evidently survives the events of Geneforge, as she is one of the serviles smuggled out of Sucia Island and taken to Drypeak by Zakary and Barzahl.
In Geneforge 1, she warns the player to ignore Clakkit, whom she believes is incompetent. During the events of Geneforge 2 she serves as an undercover agent of sorts, recruiting serviles from Drypeak into the ranks of the Awakened.
