Bone Cathedral
What is "Bone Cathedral"?
Bone Cathedral is a TTRPG dungeon archetype with an evidence-grounded backstory, a layered map, three signature encounters, and a central puzzle that ties to your campaign's living lore. Drop it into Tabletop Arc and the rooms, NPCs, and treasures become canonical entities the party can revisit.
Why this dungeon works
The Bone Cathedral serves as a chilling reminder of the intertwining of life and death, a sacred place where the very architecture is stitched together with the remains of the fallen. Here, towering archways made from bleached ribs and a pulpit fashioned from a massive vertebra loom over an altar littered with offerings of bone. Much like the infamous Wave Echo Cave, this location reverberates with the whispers of the past, compelling adventurers to confront the remnants of lost souls trapped within its hallowed walls.
