Mortis Umbra Sanctuary

The Mortis Umbra Sanctuary is the terrain piece that tells your party this place belongs to something old and intentional. A shadow-death sanctum built for necromancer lair encounters, undead cult arcs, and any dungeon session where the environment itself should feel like an antagonist. Use it as the centerpiece of an undead ritual chamber, the inner sanctum of a death cult, or the kind of set dressing that makes players check the door behind them. Pre-supported STL for resin printing. Scaled for 32mm dungeons. FDM-compatible file included.
