Luminescent Being in an Underground City

Ultra-photorealistic rendering of a radiant energy being, a translucent humanoid figure formed from shifting plasma and crackling arcs of light, hovering within a vast underground city carved from basalt and glass. The creature glows with blue-white and teal hues, its body composed of wispy electric filaments that ripple as it moves, with a softly defined face and outstretched hands trailing streams of energy. Surrounding the entity is a sprawling subterranean metropolis: bioluminescent fungi and algae lighting the vaulted ceilings, carved stone arches, rusted metal walkways, suspended rails, and reflective pools of water along the wet stone floor. Neon signs, glowing vents, and glass tunnels illuminate the scene with a cinematic, high-contrast glow; dust motes drift in the air and volumetric fog enhances the sense of scale. The composition emphasizes micro-textures on the energy being and hyper-detailed surroundings, using a wide cinematic angle (28-35mm) for depth and grandeur.
