What is "Plague Laboratory"?
Plague Laboratory 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 Plague Laboratory is a sinister hive of alchemical misdeeds, where the air is thick with the stench of decay and the flickering light of corrupted potions casts shadows on the stone walls. Within its grim confines, twisted experiments and caged monstrosities await, their ghastly forms a testament to the unscrupulous pursuits of their makers. Much like the Cragmaw Hideout, this space serves as a microcosm of menace, offering opportunities for perilous encounters and mind-bending puzzles.
