Lionhead hasn't just been working on the PC port of Fable III these past months. They've also been preparing a new add-on for the game called "Traitor's Keep."

"Traitor's Keep" adds three new area's for you to explore: Ravenscar Keep, Clockwork Island, and the Godwin Estate. Players will encounter a "mysterious prisoner" and that's all we know about the plot for now. Lionhead also threw in 250G worth of Achievements and some unnamed extras.

The DLC will be available through Xbox Live on March 1st. It'll set you back 560 MS Points, or $7.
