Concept: a D&D adventure where the party awakens in a dungeon with no memory of how they got there. The dungeon consists of a series of tunnels with perfectly circular cross-sections connecting large, brightly lit chambers with uneven floors. The air is dry and drafty, and the dark corners are populated by skittering robot-like imps that seem to be obsessed with stealing objects made of organic materials and running away with them; otherwise, there initially isn’t much in the way of threats.
After a series of increasingly strange misadventures, including several encounters with very confused demons, it transpires that the party has been damned to Hell by an evil lich’s spell, but due to an administrative mixup by the infernal bureaucracy, they’ve mistakenly been sent to Hell for gelatinous cubes.
@kyliafanfiction replied:
Gelatinous cubes have a hell to go to?
D&D’s default cosmology has lots of Hells.
Does the party run into any deeply miserable gelatinous cubes along the way?
Gelatinous cubes in Gelatinous Cube Hell have been granted sapience and the power of speech that they might more keenly appreciate the quality of their suffering. Every last one of them is voiced by the late Alan Rickman.
the biggest plot twist is that the party of adventurers were slimes all along
