The Seven (Arcturia, Jhesiyra Kestellharp, Muiral the Misshapen, Nester, Marambra Nyghsteel, Rantantar, and Trobriand the Metal Mage), Halaster's apprentices, abandon the surface Hold and enter the dark ways of Undermountain hoping to establish their own holdings. The tower and surface holdings fall into decay and ruin, and the tribes of Blackcloak Hold, as the settlement had come to be known, quickly grows. »
Jhesiyra Kestellharp, an ex-apprentice of Halaster Blackcloak, accepts the office of Magister. »
For reasons unknown, Jhesiyra Kestelharp (the current Magister) transforms herself into a living wish spell. She is able to disappear and appear anywhere. She is later abducted by Halaster Blackcloak and forces her to create more living spells for the Mad Mage.
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.
After Jhesiyra becomes a living spell, the office of Magister passes to the mage Nerren Prentiyuel. Nither Azuth or Mystra are willing to speak of this incident. »
