What is "Iron Foundry"?
Iron Foundry 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 Iron Foundry is a colossal industrial complex where molten metal flows like lifeblood, and the rhythmic clang of hammers echoes through dimly lit halls. For adventurers, it serves as a treacherous battleground, hiding ancient forges and cunning automatons that guard their secrets. As seen in the Wave Echo Cave, the foundry's intricate machinery and enchanted ores offer not only challenges but also opportunities for powerful artifacts and treasure waiting to be unearthed.
