Blue Crystals in a Dark Night Cave

Blue mystical crystals rise among dark rocks in a cave beside a nighttime body of water. Their intense glow illuminates the nearby stones and forms pale blue reflections across the surface. Small sparks appear around the crystal formations, adding points of light against the surrounding darkness. The rocky coast remains mostly in shadow, while the water mirrors the luminescent shapes and scattered highlights. The brightest areas remain close to the crystals, while the cave walls fade into the dark background. The scene combines a cave, stones, water, reflection, and nocturnal blue light without visible characters or structures.
