One Page Dungeon: Crypt of the Deep God (Free D&D 5e / TTRPG)

Description

Villagers are vanishing from the roads. Caravans lie destroyed in the mud. Rumors speak of dark rituals performed beneath the old ruins… It is time for heroes to step up and put an end to an evil cult! But what eldritch horror truly lurks within the Crypt of the Deep God?

Crypt of the Deep God is a versatile, system-neutral One Page Dungeon designed for medieval-fantasy tabletop roleplaying games (such as Dungeons & Dragons 5e, Pathfinder 2e, OSR, or Shadowdark).

Whether you need a quick one-shot adventure, a dangerous side quest for an ongoing campaign, or a emergency session filler when your players go off-track, this tabletop module delivers instant immersion with minimal prep time.

• Pick Your System: Scale enemy armor classes and hit points to match your RPG of choice (e.g., standard Cultist stats in D&D 5e work perfectly).
