Dungeon Example
Lich Sanctum
What is "Lich Sanctum"?
Lich Sanctum 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 Lich Sanctum looms as a dread fortress, a nexus of twisted arcane energies and undead minions. Deep within its shadowy recesses, ancient tomes rest on pedestals of bone, their pages whispering secrets of long-forgotten spells. Like Wave Echo Cave, this sinister stronghold invites adventurers to explore its cryptic chambers, but its magic-infused traps and lingering aura of necromancy set it apart from mere treasures hidden by the living.
Seen in real campaigns
