This sprawling underground network features uneven limestone floors, treacherous stalagmite formations, and deep shadow pockets perfect for creeping horrors. The centerpiece is the massive, calcified husk of a giant spider, providing both an unsettling atmosphere and significant heavy cover for investigators caught in a firefight or ambush. Navigating the cavern requires careful attention to the natural chokepoints formed by rock pillars and sudden drops. VTT integration can leverage dynamic lighting to cast eerie, shifting shadows across the fossilized legs, while the narrow tunnel entrances allow Keepers to funnel cultists or spawn unspeakable terrors from the darkness.
