A colossal, ancient temple submerged beneath the ocean, encrusted with barnacles and algae, with tendrils of seaweed drifting through the water. The temple walls are carved with unsettling, intricate patterns depicting eldritch horrors. Pale green light filters down from the surface, casting eerie shadows. In the center, a massive statue of Cthulhu looms, its eyes glowing faintly with an otherworldly blue light.
