An eerie underground cavern with a dark lake, stone pillars, and haunting faces reflected in the water. A broken wooden walkway and glowing moss add to the somber atmosphere.

A vast subterranean cavern called The Echo Reservoir. The centerpiece is a massive underground lake, its black surface so still it reflects like a perfect mirror. The water shimmers with faint ripples that distort into haunting faces and silhouettes when sound is made. The cavern walls rise high and are slick with condensation, lit faintly by clusters of phosphorescent moss. Stone pillars emerge from the water like drowned ruins, some carved with worn, indecipherable markings. The air feels dense, carrying whispers that echo endlessly, as if the reservoir itself is listening. Broken wooden walkways cling to the rock edge, leading to nowhere. The atmosphere should feel eerie, quiet yet alive, a liminal place of memory and haunting resonance. See more
