Seven Kingdoms: Seowyn's Crossing
Very little is known of Captain Hellstrom, the undead captain of the cursed ship, Dagon’s Wrath. It’s not even clear what kind of undead he is, but it’s clear that he and his evil crew are filled with a fury against all the living. It’s often said that hate fills the sails of the Dagon’s Wrath and drives her like a storm.
Most agree that Hellstrom was a pirate. The usual story is that he made a deal with Dagon to serve the Demon Prince after death, and now he sails the Seven Seas sending more souls to his infernal master.
