Chained Duel on a Colossal Titan in a Volcanic Canyon

the prompt

15-second cinematic action sequence on the chains of a colossal buried titan emerging from a volcanic canyon, molten rivers exploding upward, ash clouds consuming the horizon.  
0.0–3.0s: Camera races through volcanic smoke as a fire-armored gladiator slides down a giant rusted chain suspended over lava. In the distance, the titan’s eye slowly opens.  
3.0–6.0s: A rogue spearwoman launches from a collapsing cliffside onto the chain. The camera swings beneath them showing lava far below.  
6.0–9.0s: Weapons collide, molten sparks erupting outward while the titan’s movement violently jerks the chains through the canyon.  
9.0–12.0s: Mid-combat sprint along swinging chains as volcanic debris rains downward and massive stone hands emerge from beneath the earth.  
12.0–15.0s: Wide cinematic pull-back revealing the titan rising from the canyon while the duel continues on its moving chains.
