All of the Archives have been built by Zoltun Kulle, one of the original members of the Horadrim who helped capture the Prime Evils the first time. As his disagreements with the rest of the Horadrim grew, he decided to conduct his own experiments, particularly concerning the creation of his own Black Soulstone. To do so, he created the Archives, using nothing but his sheer force of will: a place where he could perform his research and experiments undisturbed. Inside, he amassed ancient scrolls and tomes, and thousands of Demon and Undead guardians were either summoned, conjured or enslaved. Within the Archives, there are many bookshelves, traps, arcane devices and portals.
