Vanrak Moonstar

Lord Vanrak Moonstar was once a noble and a noted Waterdhavian explorer. Corrupted by Shar, he later became a death knight who led a large cult of Shar in Vanrakdoom, part of the vast Undermountain complex beneath Waterdeep.

Activities
After his transformation into a death knight, Vanrak largely occupied himself with expanding the influence of Shar and skirmishing with the followers of Selûne in Waterdeep. His greatest success was in the Year of the Tomb, 1182 DR, when he got past the Moonmaiden's protectors and burned down the High House of Stars from within. He also befriended a former bronze dragon, Glyster (transformed by the priests into a shadow dragon, who took the name Umbraxakar), who served as his companion, guide, and mount.
