The Bethesda Blog has information they teased yesterday about new DLC for Dishonored, revealing plans for The Brigmore Witches, an upcoming pack that will conclude the saga of Daud, and determine if this leads to darkness or redemption. The DLC will be released on August 13th for all editions of the game except the European PS3 version, which will follow the next day, and word is this will make use of saved games from The Knife of Dunwall DLC. They offer some screenshots and promised more details soon, and in the meantime this outline shows what to expect:

In The Brigmore Witches, continue your journey as the legendary assassin, Daud, and bring his twisted narrative that began with The Knife of Dunwall to a close. After discovering the identity and intentions of Delilah, the leader of the Brigmore Witch coven, you set out to disrupt her from completing a powerful ritual that will spell your doom. Having already been betrayed by your lieutenant, Billie Lurk, you must rely on feuding gang factions—the Dead Eels and the Hatters—to negotiate your way through previously unseen districts of Dunwall en route to Delilah’s stronghold. Regardless of the way you reach your destination, one thing is for certain – you will finally answer for your treacherous actions and fall before the mercy, or punishment, of the Royal Bodyguard and Assassin, Corvo Attano. Additionally, your power, weapon and item upgrades, Chaos level, and player actions from The Knife of Dunwall will carry over via a compatible save file option.
