Magma Demon Medieval Siege

A colossal demonic creature with obsidian skin cracked by flowing magma, gigantic horns piercing through smoke clouds, glowing eyes radiating pure rage
Emerges from beneath the earth and rampages through a medieval kingdom, crushing castles with its bare hands while armies desperately attack from every direction
Dark fantasy apocalypse with burning villages, collapsing cathedrals, lava fissures splitting the ground and dragons circling through ash-filled skies
Begins with ground-level tracking as cracks spread violently through the city, sudden eruption sending debris flying toward the camera, whip pans following collapsing towers, aerial orbit around the demon roaring through flames, fire and molten rock flooding the frame, ending with the demon standing atop the destroyed kingdom while the last remaining castle collapses behind it into lava, camera slowly pulling back through smoke revealing complete annihilation across the horizon
