A series of devastating tornadoes, unleashed by enemy mages in the recent war has left all the king's castles in ruin. Only the foundations of these once magnificent monuments remain. He has charged his sons with rebuilding his castles and promised the throne to the one who can rebuild the tallest and largest castles. Each prince has 6 knights to supervise the building. Two or more princes may work together on a castle with their knights competing to control the highest towers of the castle. Once each year, the king will tour the castles, to judge the progress of each son. After he finishes the third tour, he will choose his successor and the winner!
