The dim glow of the Abyssal vein's crystal walls pulsated faintly, as though alive with a rhythm only the labyrinth itself could understand. Daniel swam cautiously, his senses heightened by the lingering tension from their last encounter. Mira followed closely, her blade drawn and her expression sharp as she scanned every flicker of movement in the shadowy expanse around them. The path ahead twisted and branched unpredictably, a living maze eager to consume the unprepared.
"Do you hear that?" Mira's voice was a hushed whisper, barely carrying over the ambient hum of the crystalline corridor.
Daniel paused, straining his heightened senses. It was faint at first, like the edge of a forgotten memory—a haunting melody that tugged at the mind. The sound was neither pleasant nor entirely dissonant, a symphony woven from fragments of unease that seemed to echo both within and outside him.
