ECOLOGY

Environment: Any

Organization: Solitary

The legendary shipbreaker is believed (and hoped!) to be the largest of the sea serpents, a true behemoth that rules the seas. It is a fearless hunter that enjoys attacking seagoing vessels and tearing out their hulls or capsizing them by ramming. It is believed by many sailors and seafarers that only one of these mighty beasts exists. Thankfully, it seems to spend most of its time hibernating.

A shipbreaker attacks ships and huge-sized creatures as its primary prey. It ignores smaller creatures except as snacks, or if directly threatened by one. Its favorite tactic is to either smash a ship’s hull with the shipbreaker’s massive snout or armored spine, or to crush the vessel by coiling the shipbreaker’s massive body around it, or to swamp it with a might slap of the creature’s tail. Once the vessel is destroyed and sinking, the shipbreaker feasts on the drowning sailors in the water.

The shipbreaker is most often sighted well out of sight from land. It has been known to shadow a ship for hours or days, letting its mere presence instill terror in the crew, as they know there’s no escape from the coming calamity.

It is unknown what language the shipbreaker speaks or understands, if any, because no one has ever reported hearing anything but terrifying bellows from it. In fact, the creature understands and can speak both Aquan and Common, but it almost never does. What could a mortal possibly say that would merit a response from the shipbreaker?

A shipbreaker can drag itself across reefs and even onto dry land with its broad, flat flippers, but it seldom has any reason to. If the shipbreaker is bent on destroying a ship and its crew, even taking shelter in a shallow lagoon or abandoning the ship entirely to seek safety on an island won’t stave off the shipbreaker’s fury.
