Plot
Years after the end of the original Torchlight, an unknown culprit steals the "essence of power" of Ordrak, the evil being who had been the source of the corruption under the town of Torchlight. The player character takes on a quest to stop this villain, who is using Ordrak's power to disturb the balance between the world's six elements.
As the game progresses, the player treks across large geographical areas, corresponding to three "acts" of the story and an epilogue. Act I is set in the mountainous Estherian Steppes, and Act II takes the player to a desert known as the Mana Wastes.
