Nebula Neon: Cyberpunk Castle Dungeon

Hyper-detailed cyberpunk dungeon scene inside a ruined castle. Damp stone walls, ribbed vaults, iron bars, rusted chains, and dripping water. Neon tubes and holographic panels run along arches; circuitry and braids glow in magenta, cyan, and electric purple. A vivid nebula spills through a shattered skylight, bathing the dungeon floor and prisoners with swirling cosmic light. Holographic starfields hover, drones buzz, neon glyphs crawl along damp stone. A prisoner with cybernetic implants leans against the wall, illuminated by neon glow; mist, cobwebs, and bioluminescent fungi cling to surfaces. The contrast of medieval architecture and futuristic tech, moody rain-slick lighting, ultra-detailed textures, cinematic composition, digital art quality.
