From the manufacturer about Catan Legend of the Sea Robbers:
Seventy years after the arrival of the first settlers, the Catanians have expanded throughout Catan. In Catan: Legend of the Sea Robbers, you and your fellow clan leaders play through four linked chapters, exploring new surroundings by sea. In each chapter, the Council of Catan provides a special mission that not only benefits your clan, but helps maintain peace throughout these new lands. Faced with the threat of the Sea Robbers, it is important for you to work to benefit your clan and open up new regions by building roads and settlements, always being mindful of Catan’s common good. The tasks given by the Council are their own reward and the ultimate goal—finding the right balance between strengthening your clan and completing these missions is key to the prosperity of Catan! This is not a standalone product. A copy of the Catan and Catan: Seafarers is required to play.
