Returning to Cain again, the scholar told Aidan of what lurked beneath the labyrinth- Diablo, Lord of Terror. A youth had been sacrificed to whatever dark power he served, but it wasn't Albrecht.

Lazarus was powerful and had many demons at his side, but in the end, he was struck down. With this knowledge, Aidan and his companions made their way to the Unholy Altar. Cain was not sure what to make of it, but realized that Lazarus himself must have kidnapped Albrecht. Returning to Tristram, Aidan presented the staff to Deckard Cain, claiming that it was clear that Lazarus had deceived his people. The same bishop had led Tristram's people into the labyrinth to be slaughtered before disappearing. The heroes pressed on, making their way into the catacombs under the monastery, eventually discovering the Staff of Lazarus, which belonged to the bishop that had been Leoric's advisor. Aidan brought news of the king's death before returning into the labyrinth. Witnessing the reanimated visage of his father was a harrowing encounter for Aidan, made even more heartbreaking by the fact that he was forced to strike him down. Quickly dispatching a demon called the Butcher, they soon encountered Leoric, now the Skeleton King. Venturing into the cathedral, Aidan and his companions faced the horror and might of the Burning Hells. Cain also pointed out that there were others who could aid him and as such he was joined by a Rogue named Moreina, who was part of the Sisters of the Sightless Eye and a Vizjerei Sorcerer, Jazreth. He warned Aidan of the demons beneath the cathedral and of the undead, how he might have to face those he once knew. Īidan vowed to rescue his brother and banish whatever power had gripped the kingdom, though Cain urged caution. His father had been struck down by the knight Lachdanan, Albrecht was missing and his kingdom was in shambles.

By the time Aidan arrived, things had gotten even worse. Aidan survived however, and made his way back to Tristram, already suffering under whatever evil was plaguing it and drawing numerous adventurers to the town because of it (that, and gold). The war against Westmarch was a disaster, the armies of Khanduras being cut to shreds. Ogden greets Aidan upon his return ( src)
