Thousands of ships, some with red and amber sails, others with white diamond-shaped sails bearing a star emblem, clash in a chaotic melee. The ships are locked in close combat, with archers firing flaming arrows and catapults launching fiery projectiles. The water churns with the impact of the attacks, and debris litters the surface.
