We may be small now, but one day we shall be a legend!
The Classic King’s kingdom is just getting started. He doesn’t have much land or treasure yet, or even his own little village to rule, but he’s already recruited fourteen brave and loyal knights, and by working together they have constructed a fine golden castle. It has battlements and a flag and a drawbridge and everything!
Creating a brand-new kingdom isn’t easy, but the Classic King is full of big ideas. He imagines that one day, the world will be full of castles and fortresses and inns and forests. There may even be horses for his knights to ride…though for right now, they’ll have to build their own!
