Starfall Bridge — Crystal Span Crossing

10-second magical crossing, 16:9. The Starfall Bridge: a span of living crystal arcing over a chasm where a river of stars seems to flow far below.

0-3s: The approach along the bridge's length. The crystal hums faintly under the light — the span grown, not built, its facets catching the night in prismatic flashes. Far below, the chasm holds a river of stars, flowing slow and silver. Elven travelers pass with lanterns, and the bridge magnifies each flame into a constellation, the light blooming through the crystal.

3-7s: Midway. The bridge sings — a single clear note, resonant — and the stars below brighten in answer, the river flaring silver. The camera moves forward along the span, the crystal's hum deepening, the travelers' lantern-constellations wheeling in the facets. The chasm's depth is vertiginous, the star-river endless.

7-10s: The far side. The bridge meets the elven shore, its crystal dimming to a soft glow, the travelers' lanterns steadying. Behind, the span arcs back into the night, humming. Magical. Vertiginous. Beautiful.

Craft: the living crystal's facets and faint hum-glow, the star-river's silver flow in the chasm, the lanterns magnified to constellations; the elven travelers' robes and the shore's dark trees. Camera: smooth forward crossing along the bridge's length, the midway hold on the song, 35mm feel. Lighting: crystal light on night blue, the lantern gold, the star-river's silver. Atmosphere: magical, vertiginous, beautiful. Style: fantasy cinema, luminous night grade, photorealistic, 24fps.
