Demon Gate
What is "Demon Gate"?
Demon Gate 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 Demon Gate stands as a sinister threshold between realms, infused with an unholy energy that warps the very fabric of reality. Here, players may encounter rare demonic artifacts encased in obsidian, shimmering with a malevolent glow, and hear the whispers of tormented souls echoing through the air. Just like in the Cragmaw Hideout, which serves as a hiding place for bandits, the Demon Gate challenges adventurers to confront the darkness that lurks beyond its ominous entrance.
