If you build up enough experience, you'll be able to control 2 stones at once, and combine the energies. My ultimate goal, obtain enough will to take control of all 12 stones. If I do that, I'll be given almost complete control of all existence.
In accordance with Rule #1, I'll remind you I don't have absolute power... yet. You can stop me if you want, but... if you're careless, I might just dominate the universe. Don't forget you have the ability to do the same.
