Rhinzen Halnian was a powerful Elf Wizard and the Master of the House of Wonder mage academy in Waterdeep. He spent most of his time tutoring the children of weathly Waterdavian families, a task he seemed to find excrutiatingly boring. Rhinzen got his kicks by indulging in the narcotic haepthum. He held the Song Dragon's Gorget, a magical item that nulified the effects of Waterdeep's dragon ward. Tennora Hedare, a former pupil, stole the gorget but was caught in the act by Rhinzen. However, he was so bombed out of his mind on haepthum that he mistoke Tennora and two apprentices near her for devils and called down a meteor swarm on his tower. The tower was destroyed but Rhinzen survived although he was relieved of his role as Master of the House of Wonder.
Rhinzen had blonde hair and tourquoise eyes.
