15-second Ultra-cinematic Dark Fantasy Transformation Sequence

15-second ultra-cinematic dark fantasy transformation sequence during a total solar eclipse. A lone warrior stands atop a ruined battlefield beneath an enormous eclipsed sun. The landscape is silent. Torn banners hang motionless. Black ash drifts through the air. The camera slowly circles around the warrior as the eclipse deepens. The world becomes darker with every second. Suddenly his shadow begins moving independently. At first it stretches unnaturally across the ground. Then black tendrils emerge from the darkness, slowly spiraling around his legs and armor like living smoke. The camera pushes closer as the shadow climbs his body. Black energy spreads across his skin and armor, forming intricate dark patterns that pulse with ancient power. The transformation accelerates. His cloak dissolves into flowing shadow mist. Dark particles orbit around him. The surrounding light is gradually absorbed into the growing darkness. The warrior's eyes ignite with deep violet light. Shadow armor forms across his shoulders, chest, and arms. Floating fragments of black crystal emerge around him. The eclipse reaches totality. A massive crown made of living darkness and shattered obsidian materializes above his head. Gigantic shadow wings unfold behind him, stretching across the battlefield and blotting out the remaining light. The environment reacts violently. Ash, debris, and shadows rise into the air as if gravity itself is surrendering to the transformation. Final cinematic moment: the Shadow King stands fully transformed beneath the eclipsed sun. His eyes glow through the darkness while an immense kingdom of shadow briefly appears behind him like a vision from another realm.
