Azalin Rex is an undead wizard (lich) that appears in the Dungeons & Dragons campaign settings of Worlds of Greyhawk and Ravenloft. He is the malevolent ruler of the domain of Darkon.
Description[]
As an undead wizard, Azalin's true appearance resembled a skeleton or mummy. In his everyday appearance, however, Azalin maintained the illusion of a live king, closely mimicking his late-life persona: an elderly man with aquiline features and a piercing gaze, with unkempt dark hair topped by a heavy iron crown.
However, he could alter his appearance to resemble many humanoid individuals, even that of a different race or gender. Perhaps as a result of this in-game flexibility, official portrayals of Azalin differed greatly from artist to artist, much more so than portrayals of characters such as Lord Soth or Strahd von Zarovich.
