Orin The Red is the chosen of Bhaal, god of murder, and one of the major bosses of Act Three. As a deranged acolyte of murder, Orin seeks nothing more than your goriest death as an offering to her god. To goad you into this fight, Orin will abduct a party member from your camp to force you to play her game and draw you into her lair. The party member will be whoever had the least approval with your avatar who wasn't in the party at the time of the abduction.
