Archipelago in a Subterranean Crypt

Photorealistic scene of an archipelago contained within a vast subterranean crypt. A turquoise inland sea laps against mossy stone islands crowned with palm trees, ferns, and ruined temples. The cavern features towering vaulted ceilings, weathered pillars, and damp walls covered in lichens, with pools of reflective water and subtle ripples. Warm amber lanterns and shards of muted stained glass cast glints across the water, creating long shadows. Soft moonlight filters through natural skylights and cracks in the ceiling, mingling with bioluminescent fungi along the walls. Seabirds wheel above the water as tiny waves lap the shores of the island ruins. The atmosphere is haunting, serene, and otherworldly, with photorealistic textures: wet stone, algae, carved stonework, and lush greenery contrasting with ancient ruins.
