The Leviathan

The Leviathan is a legendary ghost ship captained by a crew of cursed ghouls known as The Damned. Not much is known of the ship, or if the ship and its crew even exist, but it's been a prominent part of pirate folklore for centuries and there is a decent amount of evidence pointing towards its existence.

Sightings
The Leviathan has been spotted by several sailors over the years, and the descriptions have been varied, but tend to follow one central theme. The Leviathan is said to always bring a storm in its wake, and is somehow able to flawlessly maneuver through it while other ships are shredded to ribbons. The ship is also said to be almost entirely built of human remains and old, rotting driftwood. It's adorned with the bones, teeth, and nails of the fallen. Everything about the ship is horrifying, especially the flag it bears.

The crew is said to be a group of emaciated pale humanoids commonly referred to as the Damned. Old legend suggests that they were once humans cursed by the Divines for some long forgotten act of treachery. The ship is often spotted near the Maelstrom of Bal, and is sighted most often to the far west.

The acts of violence commited by the crew are terrible. Several ships have been discovered, drifting aimlessly over the Abecean with their entire crews viciously slaughtered or crucified to be made an example out of. All of the deaths are gruesome and torturous, leading one to consider why a crew would be so cruel.

Sightings of The Leviathan have grown exponentially more common with news of the Elder Scroll getting out, as has their body count and the ferocity of their attacks.
