It is time to put a stop to the marauders! For years the coastal towns have been burned and looted by the forces of evil. You and your fellow adventurers have been recruited to root out and destroy the source of these raids. But beware, hundreds of good men and women have been taken by the slavers and have never been seen or heard from again!
Highport was once a human city, but the land and town have been overrun by humanoids – orcs, goblins, kobolds, ogres, and gnolls. Looted, burned, and ill-kept, the city has become a base for human outcasts wishing to deal with these unsavory creatures. Your party, provided with transport, has managed to arrive in Highport and pose as one of these groups come to deal.
For several years, organized bands of pirates and slavers have made a living by raiding the coastal towns on the Sea of Gearnat. Ranging from Onnwal to the Wild Coast, they have descended quickly and ruthlessly on the small towns and villages and carried off innocent citizens into the night. Although these marauders were not approved of by the lords and rulers of the lands they raided, they were allowed to continue their depredations. Feuding amongst the lords and lack of funds prevented all but an occasional naval battle with the villains and the slow fortification of towns. Bribery was often a more effective method of protecting one’s lands from the incursions of these avaricious seawolves.
