Dungeons & Dragons Daggerdale centers on the desperate struggle to defeat the evil Rezlus and his Zhentarim in their attempt to invade and conquer the Dalelands. Players are charged with the task of restoring order to the Dalelands by unlocking the secrets of the Mines of Tethyamar, defeating the evil within the treacherous Tower of the Void, leading to the final confrontation with Rezlus himself.
The game is the first in a planned trilogy of video games.
