Changes

The [[Horadrim]] were charged with keeping the Soulstones after they had successfully captured the three prime evils. They took them to three different locations within [[Sanctuary]], in order to isolate one prime evil in the event that he should escape.

[[Mephisto]]'s soulstone was taken to a [[Zakarum]] temple in Kurast. Mephisto was able to take control of his '''soulstone''', which eventually led to the corruption of the uppermost ranks in the priesthood of the Zakarum.

[[Diablo]]'s soulstone was taken to the Horadric monastery in [[Tristram]]. The monastery was abandoned when the Horadrim who, having no quests left to undertake, faded into legend. The soulstone was rediscovered by [[Lazarus]] - a high priest of the Zakarum - and awoke Diablo. It is thought that Diablo's awakening was indirectly caused by Mephisto.

[[Baal]]'s soulstone was taken to the depths of a desert temple in [[Lut Gholein]]. Baal damaged his soulstone before he was imprisoned, and thus the largest fragment was not adequate to contain him. [[Tal Rasha]] offered himself as an extension of the damaged soulstone, and Baal was contained. He was later freed by his brother, Diablo (The [[Dark Wanderer]]), who was accompanied by [[Marius]]. Marius held Baal's soulstone until Baal later retook it.
