Zoltun Kulle was one of the founders of the Horadrim, but turned towards the side of darkness after the creation of the Black Soulstone. He was the most powerful man in all of Sanctuary, and the Horadrim realized this. The forces of Sanctuary then banded together and severed Kulle’s body into two jars of blood, his head, and his body.
Rise of the Prime Evils
Many years later after Kulle’s defeat at the hands of the Horadrim, the Prime Evils returned and began to attack Sanctuary with the Evil’s Demonic Legion. The band of warriors then hunted each of them down one by one, until Baal remained. Diablo 3 Gold. Baal then lay seige to Sescheron and corrupted the Worldstone, which Archangel Tyrael then destroyed after a band of heroes kills Baal. After the Worldstone’s destruction, the High Heavens and Burning Hells were revealed to Sanctuary.
The Final Lords of Hell
About twenty years later, Belial and Azmodan began to plot to overtake humanity. A group of nephalem battled their way through the Legion, and meet a witch, Adria, who told them of a soulstone that could trap all the Great Evils inside of it. However, they would need to find the head, blood, and body of Zoltun Kulle in order to find it. After finding the blood and fighting through the Archives of Zoltun Kulle, they came across the soulstone chamber. Kulle double-crossed the group, and the nephalem were forced to kill Kulle once and for all and take the Black Soulstone for themselves.
Kulle was one of the founding members of the Horadric order with the assistance of six other powerful mages. He had a great talent in alchemy, and was a member of the Ennead Clan. After the capture of Mephisto, Diablo, and Baal, Zoltun Kulle began an invention which could imprision the Great Evils and the angels of the High Heavens, the Black Soulstone. The creation of it drove him mad, and all he could think about was completing the soulstone. Jered Cain then realized that Kulle has learned the secrets of immortality, and he and the Horadrim hunted down Kulle and split his body into a different dimension.
