prologue
A small vortex open in a barren waste land...A lesser evil came out
named Andariel. "Why must I come here again," she asked herself,
"why doesn't diablo come here himself?" But she still went with her orders
to set up camp at a monastery by a amazon's camp.
"Hail and sacrifice to Diablo - Lord of Terror and destroyer of souls. When I awoke my master from his sleep, he attempted to possess a mortal's form. Diablo attempted to claim the body of King Leoric, but my master was too weak from his imprisonment. My Lord required a simple and innocent anchor to this world, and so found the boy Albrecht to be perfect for the task. While the good King Leoric was left maddened by Diablo's unsuccessful possession, I kidnapped his son Albrecht and brought him before my master. I now await be rewarded when he at last emerges as the lord of this world."
Three heroes facing off against the maddened King Leoric
A conquering hero known as Leoric established himself as the king of Khanduras, a kingdom on the Western continent of Sanctuary. He appointed Tristram as the capital of this kingdom and used the abandoned cathedral there as his throne and central point of governance. Not soon after, King Leoric's most trusted advisor Archbishop Lazarus was drawn deeper into the cathedral by the Lord of Terror's Soulstone. The Archbishop, whether out of fear or temptation, shattered the Soulstone, releasing Diablo's trapped spirit. Unable to take King Leoric himself as a physical host, Diablo had the Archbishop Lazarus kidnap the king's son, Prince Albrecht, and brought him down into the Cathedral for Diablo to corrupt and use as his host to fully manifest as the Lord of Terror.
The King went mad in his search for his lost son, sending many to their death out of suspicion of guilt. Ultimately Lazarus led the town's warriors into the cathedral as a trap for The Butcher, a minion wielding a bloody cleaver. King Leoric's physical form had withered away, but his soul found no peace and returned as a giant Skeleton, wearing still his golden crown.
Several heroes travel to Tristram, hearing rumors of a corrupting evil, vast riches, and arcane magic. The Horadrim member Deckard Cain assists the heroes in their journeys. Canonically, however, it was the playable Warrior character who seeks and ultimately vanquishes Diablo. Thought able to contend with its evil, the Warrior forces Diablo's Soulstone into his own forehead. After returning to Tristram, the town's inhabitants celebrates their champion's victory, but the Hero returns a much changed man, haunted by Diablo's essence.
The Hero departs Tristram and travels to the East for answers to his nightmares.
Chapter 1
The champion becomes The Dark Wanderer, and begins to journey onwards towards the Rogue Monastery. Once there, he drives the Sisters of the Sightless Eye out of their monastery, and tasks Andariel with the guarding of the pass from anyone who might follow.
As did heroes arrive in Tristram to find adventure, glory, or riches, more arrive in the Rogue Encampment for similar reasons. A band of adventurers form and seek the Monastery and the evils that lie within. On their way, they rescue Deckard Cain from an overrun Tristram. Cain guides them on their way to the Monastery, where they defeat Andariel and find clear passage to Lut Gholein.
