Once a mighty pirate ship, Deathwail was captained by the dreaded pirate known as simply as Redeye. A man prone to unspeakable acts of Violence, Redeye and his ship Deathwail were finally destroyed in a horrible battle. However, Redeye was not to be counted out. Prior to the battle, he had plundered an ancient tomb, and had found a relic which he had kept. This item was cursed, and when he and his crew died, it brought them back in a horrible mockery of life. Enslaved by this relic, the pirates scour the waters, looking for souls that can be fed to the evil relic
