Kneeling magma warrior crowned with fire on volcanic ground

A titanic warrior forged from magma and rock, kneeling on cracked volcanic ground, his massive body criss-crossed with veins of incandescent lava. His dark, mineral skin cracks under the internal heat, letting out a burning orange-red light. Fiery flames rise from his head like a hellish crown, and his burning eyes glow with ancient rage. He holds a colossal sword of pure fire, planted in the scorching earth, its molten blade spewing flames and sparks. Embers and flaming rock fragments rise around him, witnesses to uncontrollable destructive power. Background: a cosmic apocalyptic landscape, a vast volcanic plain torn apart by rivers of lava. On the horizon, a giant, molten, cracked and incandescent planet dominates the dark sky. Flaming meteors streak across the atmosphere, leaving trails of fire, while several moons and planets float in space, accentuating the cosmic scale of the scene. End-of-the-world atmosphere, dark sky laden with ash, dramatic red and orange light contrasting with deep shadows. Dark fantasy/science fantasy style, ultra-detailed, cinematic rendering, volumetric lighting, high contrast, realistic rock and lava textures, mythological and apocalyptic atmosphere, epic concept art, high resolution, 8K.
