Barthus Ardoc is a member of the famous Ardoc family, golem-crafters of the Varisian city of Kaer Maga. Years ago, he and his fellow-wizard friend Lysanar went exploring in the Undercity below Kaer Maga. They delved further than any had in a very long time, discovering a series of rooms known as the Vault of Sleepers. Both attempted to understand the origins and nature of the hundreds of stone soldier statues they found there. Barthus, with his background in golem-crafting, believed them to be some sort of construct, and worked hard to find the correct command word. Lysanar's views were different, but neither of them had any success in discovering the true purpose behind the stone soldiers. Both retreated to the surface where they researched their respective theories, but to no avail. In the process, however, they became increasingly competitive with each other, and developed significant paranoia, worried that the other would discover the Vault's secrets. They finally ensconced themselves permanently in neighboring rooms within the Vault, working feverishly to prove their theories correct. The approaches to both chambers are heavily trapped, as both wizards fear others encroaching and taking credit for their incredible find. Neither visits the surface any more, conjuring whatever supplies they need to continue their obsessive research.
