Crystal dragon sleeping inside a glowing cave

a colossal dragon, its entire body formed from translucent, fractal-edged crystal that refracts prismatic light across the cavern walls. Nestled in the heart of a bioluminescent cave, the creature’s ribcage rises and falls in slow slumber, each breath stirring the glowing fungal tendrils carpeting the floor. The dragon’s wings—veined with opalescent filaments—are half-furled, casting jagged shadows over stalactites dripping with luminous sap. Deep within its chest, a pulsing core of molten gold throbs like a heartbeat, illuminating the cavern with shifting hues of amber and violet. Mist curls from its nostrils, crystallizing midair into tiny, floating geodes that clatter softly as they fall onto the shimmering mineral crust below.
