:"As my readers are well aware, early Vizjerei writings are often little more than self-serving propaganda aimed at whitewashing heinous deeds committed by the mage clan."

Zoltun Kulle was among the founding members of the Horadrim, alongside six other mages. Records passed down from Jered Cain to his descendant, Deckard Cain, implied Zoltun Kulle was an accomplished member of the Ennead clain, implying implicit skill in transmutation, alteration and alchemy. While Kulle originally proved to be a noble and insightful addition to the Horadric brotherhood, the hunt for the three Prime Evils left him hollow and twisted. He endeavored to craft a soulstone empowered to contain the souls of angels and demons. While its creation may have originally been an attempt at repairing his broken spirit, an aspect of madness and hunger for power manifested itself. At some point in the throes of madness, Kulle was convinced that this Black Soulstone would prove critical in saving mankind from an unseen threat.

The remainder of the Horadrim learned of Zoltun Kulle's experiments. Under Jered Cain, the brotherhood hunted down their former comrade-in-arms. Although Kulle was acknowledged as being one of the most powerful beings in the world, the combined efforts of the Horadrim finally defeated him. The Black Soulstone, though left incomplete by Kulle, was never found by the Horadrim.
