A goblin warband has found the secret tunnel which leads from the dwarven keep of Hearth-Home to the nearby hills. The tunnel is intended to be a means of escape if the keep ever falls to attackers, but now it has provided goblins with an easy way into the Underkeep. So far, the goblins have confined their attentions to the various underground rooms that make up the Underkeep, but sooner or later they will find a way to the surface. They pose a serious threat to Hearth-Home - the goblins must be cleared out of the Underkeep so this breach in security can be repaired before the orcs hear of it and overrun the dwarven keep. This adventure is slightly more challenging than Red Hand Trail, and it is recommended that it is played after that quest and before Palace of Dread. However, the scenario in Trouble Below can easily be played independently from the rest. Part of TSR 1076 The Goblin's Lair

Part megadungeon, part underground expedition, Operation Unfathomable serves as both a one-shot adventure and a campaign framework. PCs are (optionally) drafted at swordpoint to recover the Nul Rod, a priceless artifact that was recently lost in a local prince's foolhardy attempt to destroy the Chaos Gods of the Underworld. The PCs have been drafted as an expendable set of pawns to venture into the vast and bewildering Underworld and retrieve the Nul Rod. With the Underworld's innumerable beasties being on high alert after the prince's expedition, the PCs must sneak through the incredibly dangerous Underworld. Fighting is not as important as stealth, fast-talking, and running away rapidly. This is the expansion from Sholtis's original Operation Unfathomable, released in Knockspell #5 (2011).

Gray Mountain lies deep in the lush elven forest. The temple there was a haven of meditation and learning - until taken over by an evil cleric known as the Rahib. Far under the mountain, he paces before the temple's great altar. A brown-robed servant rushes in and falls to his knees, trembling at the sight of the Rahib's black panther. "Rahib, adventurers came to the village as the sun rose - the strangers now protect Rahasia." A scowl crosses the Rahib's face. "I must have Rahasia! Attack again tonight." As the servant scurries away, a deep growl rises from the giant cat. Gripping the panther's leash, the Rahib paces again, speaking out loud. "We must dispose of these strangers quickly; the secret beneath the temple will not wait much longer." Note: the setting is unspecified, but certain tie-ins, like the wines, prefigure Ravenloft.
