Echo Chasm#078

Description

Cave network rendered only by echolocation: bats paint the map in expanding pulse-rings, stalactites drop on sonar-triggered timing, and blind towers fire only at sound. Signature: emit a double-pulse to triangulate the invisible prowl-beast.

Pure black canvas with white-blue pointillist echo rings, bat silhouettes, glittering calcite veins.
