Sweeping wide shot of an immense magical barrier of glowing energy cracking apart across a canyon as armored defenders brace behind it and a dark horde surges on the far side. Handheld camera shakes along the line with an urgent jolt, snapping from the barrier splintering into shards of light to soldiers raising shields against the breach to mages straining to hold the failing wall. Fragments of energy rain down, dust erupts from the canyon floor, the horde pours through the gap. Cold stone grays and brilliant pale-gold light, vast desperate scale and chaos. 16:9, 10 seconds.
