The Binder's Sanctum Dungeon

The Binder’s Sanctum

The Binder’s Sanctum is a dungeon for fantasy roleplaying games set in a forest environment. The dungeon is setting and system neutral for easy adaption and improvisation.


The Binder’s Sanctum is the ruins of an old wizard’s stronghold on the outskirts of an ancient forest. The Binder was an artificer who built golems as guards against the demons hiding in the shadows of the Old Empire.

Invaders, cultists and monsters has rebuilt, destroyed and looted the site numerous times since the Fall of the Old Empire. Little remain of the ruin’s original structures.  Scholars and rangers have gathered what information still exists about the site, although much is lost.

Yet secrets remain below, old spells linger here drawing those who seek to tap the dark powers the Binder drew on.


The Binder’s Sanctum has at least two entrances. Only the stairs in the ruins is known to rangers and scholars.

Overgrown Grand Stair. The dungeons has one known entrance, an overgrown and half-covered grand stair down in the ruins on a hilltop in the forest. The stairs are overgrown is moss and vines, and cracked from wear and exposure.

The Dragon Cave Tunnel. The lower level of the dungeon is a vast cave believed to be lair for a brood of dragons. Some ranger claim having seen a narrow cave in the overgrown side of a nearby hillside, but none have explored them beyond the entrance and a few caves below and returned alive.


The walls of the dungeon are masonic stone. Most of the areas have 10-foot ceilings. Vines, moss, and fungi cover all surfaces, and there is a thin layer of festering slush on the floor. Soot cover the walls and ceiling.

The Demon’s Foyer and the Binder’s Lab

The Binder’s Sanctum Entry Hall. A large stone, partially destroyed, statue of the Demon Lord dominate the entry hall. The ceiling is 20 foot high in this area.

The Binder’s Old Quarters. The Binder lived in cramped living quarters close to the lab in the innermost part of the dungeon. Cultist refurnished the area with a dark altar at some point, and still occasionally use the area as a safe house.

Recently a band of ogres laired here, leaving the area is littered with garbage, broken goods, and rotting carcasses.

The Binder’s Ritual Hall.  The hall on the left hand from the entrance is dedicated to a Great Ritual. There is powerful lingering magic here, and cultists seek to reactive the spell for unknown purposes.

The pentagram and symbols on the floor and wall may have one of several effects:

  1. Binding spells with faint strands of magic disappearing into thin air. A dark presence hangs over the room, and someone is watching from afar.
  2. Translocation diagrams and runes, and symbols representing known locations around the world.
  3. Planar diagrams point towards other worlds and runes represents.

The Dragon’s Well. The chamber on the right hand from the entrance is a 10 x 15 foot well down into the darkness of the Dragon Caves below.
