Ex-student of Halaster
For reasons unknown, Jhesiyra transformed herself into a living wish spell to attempt escape from Halaster Blackcloak, but was brought back to Undermountain by Halaster. She currently rules over other living spells in Undermountain’s Citadel of the Bloody Hand. Driven half mad by her transformation, she rules over the living spells the Mad Mage forced her to create.
Jhesiyra, in a bout of amusement, gave the PC’s her Horned Ring a minor artifact that allows the wearer to teleport within the confines of Undermountain, despite Halaster’s anti-teleport spells.
