Dishonored’s two story-expanding pieces of DLC will focus on antagonist Daud, Bethesda has announced.

The Knife of Dunwall will fill in Daud's back-story as he seeks redemption in new areas of the city including a whaling slaughterhouse, as well as familiar territory like the Flooded District.

Daud’s powers include the ability to summon supernatural assassins The Whalers, a power called Void Gaze that allows him to track hidden objects, and he also gains variations on Dishonored protagonist Corvo’s powers.

The Knife of Dunwall will be available from April 17 for Windows PC, PlayStation 3, and Xbox 360.

Later, Daud's story will be concluded in a final add-on, The Brigmore Witches.
