From publisher blurb:
A Novice adventure for Shadow of the Demon Lord
You survived the first level of the Dungeon of the Damned. You secured the key that opened the way to the horror below. Do you have what it takes to descend into the depths and confront the horrors locked away by the Mad Wizard himself? Will you have the skill and stamina to survive the perils that lay in wait? We shall see.
Dungeon of the Damned: The Gallery of Groans continues exploring the sprawling dungeon complex first revealed in Dungeon of the Damned: Looted Vaults and offers a whole new level to explore. After traversing to the depths below, the group discovers a hellish environment filled with implements of torture and its raving, sadistic inhabitants. The party must explore this hideous labyrinth to find a strange key that opens the way to the next level down while battling all manner of deranged and despicable foes.
