First-Person Medieval Fortress Siege Action

First-person POV fantasy knight (iron gauntlets, battered shield, glowing longsword, visor rim visible, heavy armored footsteps, cape snapping behind) charges through a breached castle gate, shield-bashes spearmen off the battlements, blocks arrows inches from the face, climbs a collapsing staircase, parries a brute’s axe at point-blank range, jumps onto a war beast’s back, runs along its spine and drives the sword through a horned demon commander standing atop the final tower just before the creature unleashes a fire blast, in a medieval fortress under siege (burning towers, shattered walls, clashing armies, catapult fire, storm clouds, banners whipping in the wind) (ultra-dynamic first-person melee camera, violent impact jolts, shield-led framing, short bursts of slow-fast acceleration, orange firelight mixed with blue storm light, ash, rain, embers and rubble, savage heroic atmosphere)
