Witness the rise of Catan! Life in the cities improves, some develop into magnificent metropolises. Trade flourishes and brings prosperity to the island. Unfortunately, this wealth attracts the barbarians! Hordes of savages threaten the island; who will protect the cities when they try to plunder them? The Knights of Catan are called to fight against these barbarians. If they were to succumb, the cities would have the hours numbered! This expansion contains many new elements. Cities can be transformed into metropolis thanks to new resources. All knights should fight the barbarians together, but some may refuse their support to pursue personal goals. Someone could side with the barbarians and leave their knights inactive, so that another player's city is plundered and reduced to a smoking colony.
