Baldur's Gate II: Throne of Bhaal is the expansion pack for the computer role-playing game Baldur's Gate II: Shadows of Amn, and is the final chapter in the Baldur's Gate series. It adds one large optional bonus area to the Baldur's Gate II game called Watcher's Keep, which is a multi-level dungeon of sorts. It also extends the main plot line to an epic conclusion. There are also several new powerful weapons, a higher level cap, and new class-related feats and magical skills. A novelization of the game exists, written by Drew Karpyshyn.
