Translated from the back of the book:
"'Sea of Blood'
Pirates under the banner of the Demon Crown. Unsanctuaries of the Pitiless Drowner before Rulat and the island of Maraskan, battle cruisers of Lord Commander Helme Haffax, but also blockade runners from Khunchom and grain convois from the Bornland, the heroic deeds of Admiral Rateral Sanin and the rescue boats of the Efferd Brothers - all this is part of the saga of the Sea of Blood, the maritime area between the Bay of Festum and the the Sound of Maraskan, where the fight against the heirs of Borbarad isn't decided for a long time.
Sea of Blood is a campaign module to experience adventures in the Pearl Sea controlled the followers of defeated Demon Master Borbarad, for example aboard the famous Sea-eagle Of Beilunk. The scenarios can be tied up to a complete compaign playable in parallel by two seperate groups of heroes."
