To rescue a missing noble, one brave man must venture deep into a vast labyrinth created by a crazed wizard—a place from which very few escape

Long ago, a dark wizard created a vast and deadly labyrinth beneath the city of Waterdeep, a labyrinth from which escape is nigh impossible. Now, the subterranean prison is home to creatures both human and otherwise—and to a missing noble who has been lost beneath the ground.

Trapped in his own prison, Artek the Knife is offered release if he is able to recover the nobleman from the twisting dungeon beneath Waterdeep. Everyone knows that getting inside the mysterious Undermountain is treacherous—and getting out is assuredly deadly. But for Artek and Beckla, a small time wizard who joins the mission, the risk is worth the reward.
