A lone man, a wondering traveler, stands at the mouth of an immense spiral cave carved into a sun-bleached desert cliff. The cave's walls coil inward like a cosmic nautilus shell, receding into impossible depths that vanish into star-speckled darkness. Five cracked rock fissures along the spiral path reveal a luminous underground lake that mirrors the cave's perfect curve, its turquoise water glowing with bioluminescent algae and reflecting faint auroras from unseen skylights far above.
