Expedition to Castle Ravenloft (Mavrickindigo)
Parmitt Balam was imprisoned in the bottom of a wizard’s tower centuries in the past, far before the conquest of Count Strahd von Zarovich. He was trapped within a series of four sigils and cannot leave. He took the form of a fey maiden in order to lure people deeper into the bowels of the tower in order to convince them to set him free. When he met the party, they saw through his disguise, and he had to reveal himself in order to gain their trust.
Once they rescued him and left the compound, Dubon of Barovia tried to slay him because of the power of his evil aura. Balam simply cast a spell which allowed him to escape.
