Submariner — Sea Life

The Unsinkable Bulkhead Leviathan is the wreck's answer to arrogance: a depth-five siege beast plated in watertight doors, torn hull ribs, and frost-black rivets. It rams submarines broadside, not to puncture them at first, but to test which compartments still believe they can hold. Crews say its jaws click like closing bulkhead locks just before the pressure lamps go dark.
