A colossal demon with obsidian skin and lava cracks rises from underground and crushes a medieval kingdom as dragons circle above

Prompt

A colossal demonic titan with obsidian-black skin split open by glowing rivers of molten magma rises from beneath the earth. Massive horns tear through the smoke-filled sky, and its blazing eyes burn with pure rage.
It storms through a medieval kingdom, crushing castles in its bare hands as desperate armies attack from every side. Villages burn, cathedrals collapse, lava fissures rip through the streets, and dragons circle above in ash-choked skies.

The scene begins at ground level as cracks violently spread through the city. A sudden eruption blasts debris toward the camera. The shot whip-pans past collapsing towers, then shifts into an aerial orbit around the demon as it roars through fire and molten rock.

End with the demon standing over the ruined kingdom while the final castle collapses into lava behind it. The camera slowly pulls back through thick smoke, revealing total destruction across the horizon.
