On rules and control.

All rules can be bent. For example, the king of Yotia determined that the one man who could carry the jade statue to the other side of his courtyard would marry his daughter. Many men tried to grab the statue and move it, without success. Urza, who was never know by his physical prowesses, just gave it a little spin, and manufactured a machine who would grab the statue and move it. He merely had to control it, to order it the task, and the machine would perform it for him. And it did, and Urza married the princess Kayla. This example, taken from the book The Brothers War, is an example of direct control and, of course, of ingenuity. Control, however, doesn't need to be direct. Not everything is about pulling strings.
