Sangalor

Sangalor, also known as Sangalor of the Secrets, was a mind flayer outcast who became a cleric of Oghma in 1370 DR.

Activities
In time, Sangalor became a fervent devotee of the God of Knowledge but was basically still an illithid: his usual trade was to find secrets by request or interrogating evil prisoners by eating their brains. Sangalor revealed secrets about his home city to anyone who was seriously intending to fight his evil brethren.

History
Sangalor originated from the illithid city of Ch'Chitl but at some point, for unknown reasons, it became an outcast. To survive, Sangalor turned to the worship of Oghma and moved first to Skullport and later to Waterdeep and the Temple of Oghma there.
