Enchanted Sword on a Tropical Island

Ultra-detailed 3D render of an enchanted sword embedded in warm tropical sand on a secluded island. The blade glows with a cobalt-blue aura, runes etched along the fuller, and wisps of magic curling off its edge. The ornate hilt features gold filigree, emerald inlays, and a weathered leather grip. Surrounding scenery includes swaying palm trees, crystal turquoise water, white coral-sand beach, distant emerald cliffs, and a gentle surf. Lighting: golden-hour sunlight filtering through leaves, volumetric rays, realistic global illumination, caustics on water. Camera angle: low to the ground, close-up on the blade with shallow depth of field, micro-detail on steel, subtle wear. Atmosphere: mystical, tropical, serene, with a hint of unknown power. Mist rising from shoreline, tiny shells and footprints in sand.
