Round 296

The walls' synchronized breathing stopped completely—everything except that low pulsing hum growing stronger like heartbeat counting down seconds until next adaptation phase. The symbols on the wall seem to shift, their pulsing light intensifying. The air around her grows even thicker, heavy with an otherworldly energy that makes her skin crawl. The hum of the entity's power grows louder, more insistent, until it's all she can feel. She presses herself harder against the opposite curve of the living rock, her heart pounding in sync with the walls' ominous pulse. The ground beneath her gives a slight tremor, and the sound of distant stone grinding against stone echoes through the tunnel. A faint, flickering glow begins to emanate from the walls, casting eerie shadows on the stone floor. The light is soft and blue-green, like bioluminescent fungi, but it's impossible to tell if it's natural or part of the entity's influence.

The air grows thick enough to chew, heavy and wrong against her exposed skin. She could feel it thinking—something ancient and hungry and intelligent using this flesh of stone as its hands and mouth. Every instinct screamed at her to run, but Silra needed her. The walls' synchronized breathing stopped completely—everything except that low pulsing hum growing stronger like heartbeat counting down seconds until what? She pressed herself flat against the opposite curve, trying to put distance between her skin and the shifting surface. The symbols etched deep burned brighter now, pulsing in perfect sync with the humming that vibrated up from the floor into her bones.
