Chapter IV - The Fallen Star

With the Worldstone destroyed, Sanctuary's role in the Eternal Conflict was forever changed. People largely forgot the horrors of an earlier age, and the town of New Tristram sprung up not far from where Diablo once dwelled beneath the earth.

But Deckard Cain hadn’t forgotten. He brought his adopted niece Leah to New Tristram, and continued to study the evil that had once crept from the cathedral. Cain was convinced that it was only a matter of time before doom would threaten Sanctuary again, and, for 20 years of relative safety, his warnings were easy to ignore… until a star fell from the heavens.

The star struck Tristram’s old cathedral, sending Cain plummeting into a crater and Leah rushing for help.
