Underwater ship graveyard

A top-down battle map of an underwater shipwreck site, featuring a tight cluster of three decaying vessels resting on the abyssal floor. A shattered merchant galleon lies split open in the center, flanked by a half-buried warship and a tangled fishing boat, with broken masts and barnacle-encrusted rigging creating a treacherous, labyrinthine maze. The scene is illuminated by a cold, murky twilight, with scattered glowing embers of magical residue casting faint, malevolent light against the dark, silt-covered seafloor.
