That same evening, Cain visited him, finding Aidan muttering to himself, wearing a dark garb and a hood that covered his face. Aidan eventually related his story to Deckard Cain, telling him of his battle with Diablo. After the tale, he kept mumbling, whispering "I thought I could contain it, I thought I could contain it..." before mentioning his "brothers" awaiting him in the east. Cain could see that Aidan was disturbed, but at the time, saw it as meaningless ramblings. The next day however, Aidan was gone, armed only with a sword and some provisions. According to Adria, he had traveled east, to seek out mystics who might exorcise the waking nightmare that plagued him. A half-truth. But as demons descended on Tristram after Aidan's departure, it was clear that there would be no-one from the town capable of following him.
