[Source] Olcan (aka The Poisoning Priest) is a secondary character in The Witcher 2: Assassins of Kings. He seems to serve the deities Kreve, Freya and Melitele. He is killed by King Henselt during the preamble to Chapter II when a fight between the Kaedwenis and Aedirnians breaks out. He tries to stop the bloodshed but Henselt, blinded by rage, viciously slams him into a large stone obelisk, killing him. His death unleashes a series of strange happenings, including an eclipse. Later we learn that it has unleashed the full power of Sabrina's curse.
