Years after the end of the original Torchlight, The Alchemist (playable character in the first game) becomes corrupted by the Ember Blight coming from the Heart of Ordrak, the evil being who had been the source of the corruption under the town of Torchlight, and then destroys the town.
As the game progresses, the player treks across large geographical areas, corresponding to three "acts" of the story and an epilogue [REF].
