Divine Hammer in an Underwater Cave

A photorealistic underwater scene inside an ancient cave. A divine hammer lies partially buried in sand and rubble on the cave floor. The hammer is forged from gleaming mythic metal, with an intricately engraved head, a luminous gemstone at its center, and a faint halo of light emanating from runes along the shaft. Crystal-clear water reveals suspended particles and bioluminescent corals and small fish. Stalactites hang from the ceiling; shafts of sunlight pierce the water, casting dramatic godlike beams that illuminate the hammer and create shimmering reflections on wet stone. The overall mood is solemn and sacred, as if the artifact is a relic of a forgotten deity. Hyper-detailed textures: wet metal with patina, etched runes, mossy rock, delicate sediment texture, bubbles and ripples. Shot in high-resolution photorealism with cinematic lighting, 8K quality, macro-detail on the hammer's engravings.
