In 1991, the expansion module "Kopparhavets kapare" came out for the Swedish role-playing game "Drakar och Demoner" and the module takes place in the Swedish fantasy world "Ereb Altor". Included in the expansion where rules for naval combat, which can be played together with the role-playing game or as a separate board game. You can play different peoples such as humans, "Svartfolk" (Greenskins), "Gråalver" (Sea elves), ducks etc. Why not have a sea mage on board who is a wind weaver. Participate in "Det felisiska piratkriget" (the Felician Pirate War). Enter or ram other ships in large naval battles. Fight against the black pirate ducks of the Copper sea. Or why not attack one of the greenskin's Kyrakher with galleys that ogres and trolls are rowing.
