Take heed and bear witness to the truths that lie herein...
After Diablo was defeated, the Hero embedded the Soulstone of the Lord of Terror into his forehead, hoping he will be able to master the daemon. The body of prince Albrecht retrieved its natural look and was buried in vault near the Cathedral. As the time went by, the Hero stared to feel that he is loosing the fight with the overtaking demonic force, which started to gradually make its way into his soul. Through the possessed body of the Hero, Diablo, The Lord of Terror, went east across the mighty deserts of Aranoch, which surround the ancient city of Lut Gholein, to get to the found of hell at the end, his domain, where a frightening army has already started to gather.

Many warriors, who fought against The Dark Trinity, came to settle down in Tristram, they withstood the terrible creatures with courage.
The essence of Diablo was reborn in the vault of prince Albrecht. People started to hear screams coming out of the Cathedral, and the Church itself started to emanate Terror.

There lies the Cathedral, built on the ruins of an ancient monastery, where ungodly screams heard in the town are coming from, echoing through its rooms and halls. There lies an answer, perhaps, buried in the forgotten past..."
