As you walk along one particular avenue in the crowded bazaar, you find the goods getting progressively richer and more fine. Fabrics, spices, rare beasts and fantastical street performers overwhelm your senses, until at last, you are relieved to emerge in a large empty plaza across from a magnificent palace. The center of the plaza is filled with all manner of stone blocks, and the near wall of the palace bears a gaping hole covered with scaffolding, on which a veritable horde of craftsmen are laboring. Nearby, two men are arguing.
"We're trying to finish the Prince's new palace," says the first.
"But we seem to have mixed up the blueprints, and now we can't tell which stone goes where," admits the second, rather sheepishly.
"Bah! We should have stuck to mud!" the first bleats angrily, "None of this new-fangled rock nonsense!"
While the two men continue their argument, you take a look at the pile of unused blocks. Maybe if you lend a hand, there will be a little something left over for you.
