Trisch is a knight of the Knights of the Crux Ansata in Ultima Underworld I, found on the fourth level of the Abyss, and the former keeper of the Taper of Sacrifice. She told the Avatar how she'd been responsible for the Taper of Sacrifice, until one day the mad Zak came and stole it from them in his insanity. She had no idea where he was now, as they'd lost sight of him before they could give chase. The Avatar however knew, and got the Taper back from Zak on the third level.
