Color: White Spell
Action: This is a shot of a lone figure trying to escape the carnage of the world literally blowing up around him. He is trying to run toward the camera while in one arm carrying some armor he was able to grab and in the other hand pulling the reins of a clearly panicked horse as he tries to lead it to safety with him. The background is a solid wall of explosions of various types and sizes, but they are not fire, they are a pure, cool white. He is trying to stay in front of them as they close in.
Focus: the scene (we know the figure and horse will be small, this is about the scope of the drama).
Mood: run for your life as the world explodes behind you.
