Twisted Tunnels is the fourth scenario in Conquest of the Underworld. Realizing that his nightmares are forcing him to face his darkest deeds, Tarnum decides to write down a confession of his greatest crime: poisoning his old friend Hardac and the other captains when they tried to convince him to go home and stop the war against Bracaduun. After telling them that he had been convinced, and that they could all go home, he handed them a poisoned goblet, then pretended to spill it on the ground when it was his turn to drink. He watched as they died, cursing his name.
