Tristram, a border village in the Kingdom of Khanduras on the northern continent of the Sanctuary, was once a bustling trade hub. Now, it has become the “City of Terror.” Diablo, the Lord of Terror and one of the Three Prime Evils, has broken through an ancient seal and occupied the catacombs beneath the village. His fearsome aura has corrupted the entire land: crops wither, rivers run black, and the villagers are either transformed into demons or driven mad and killed by unending terror. The only survivors are hiding in a ruined church, waiting to be saved by the legendary “Heirs of the Horadrim.”
The chilly late-autumn wind swept dead leaves through Tristram’s shattered ruins. The streets were strewn with black bloodstains and broken bones. Crooked wooden houses still smoldered, their smoke mingling with a heavy stench of sulfur and decay. Several Fallen Wraiths, the indistinct spirits of villagers corrupted by demonic terror, roamed the streets. They could shriek piercingly and disrupt the mind. Passing through ruined walls, their eyes glimmered with an eerie green light. Whenever they spotted a living creature, they let out a ghastly howl and lunged at it in a frenzy.
