"Ultra-detailed 3D render of a Steel Ogre Grotto, a towering crimson-red mechanoid with gold filigree armor plating, featuring an oversized hammerhead skull glowing with molten circuitry and a compact, heavily-jointed body. Standing in a defensive stance atop a crumbling balcony of the Phantom Fortress Enterblathnir, its piston-driven fists crackle with energy. The fortress looms with gothic spires, floating debris, and holographic siege maps projected across corroded iron walls. Dramatic low-angle shot with Unreal Engine 5 realism, Octane Render textures, and Raphael-style chiaroscuro lighting. Metallic surfaces reflect ember-like sparks, while splash ink weathering effects blend with dieselpunk rivet detailing. 8K resolution, ArtStation-trending composition, golden ratio framing, dominated by vermillion and burnished gold with chromatic aberration flares."
