In a remote land there lies a region with undulating hills and fertile valleys. Widely-travelled settlers have laid the foundation stone for the city of Arkadia. In addition to several other buildings, they want to construct a magnificent castle on a hill. Four wealthy families – the cloth merchants, the spice merchants, the carpenters and the silversmiths – want to enhance prestige and augment their influence. For this reason, they compete for the major contribution to the castle’s construction. Players act as architects. The four families commission them to plan and realise the build-up of the town and the castle.
