A knight in black plate armor with a huge glowing sword fights an army of orcs, trolls and a giant on a collapsing bridge in a thunderstorm

Prompt

A battle-worn knight in blackened plate armor stands alone on a ruined stone bridge above a bottomless canyon as an army of orcs, trolls and armored war beasts charges through a thunderstorm, the knight lowers a massive glowing sword, sprints into the first ranks, cuts through shields, slides beneath a giant’s axe and climbs onto the creature’s back while lightning tears across the sky; the bridge begins collapsing under the weight of the army, forcing the knight to leap between falling sections, drive the sword into the giant’s skull and release a wave of blue magical energy through the ancient stones; begin with an immense ultra-wide aerial view of the bridge and approaching army, descend into a low-angle tracking shot beside the knight, transition into brutal handheld combat, sharp telephoto impacts and brief slow motion during the final leap, cold moonlight mixed with orange fire, rain, sparks, flying rubble and volumetric mist, desperate mythic atmosphere, ending with the bridge exploding into glowing fragments beneath the invading army while the knight lands safely on the opposite cliff, silhouetted against a colossal lightning strike.
