What is "Frozen Fortress"?
Frozen Fortress 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 Frozen Fortress stands as a chilling testament to resilience and isolation, where frost-covered walls guard long-forgotten secrets. Echoing the imposing structure of Cragmaw Castle, this fortress features towering ice spires that glisten like diamonds under the pale moonlight, and labyrinthine passages echo with the haunting sounds of winter winds. Inside, adventurers may discover enchanted relics and the restless spirits of a bygone era, forever trapped in its icy grasp.
