After uniting the nomadic tribes of Asia, Genghis Khan rose to power and led one of the largest empires in world history.
As a lover of magic, Genghis Khan was inspired after reading "The Birds," and sought to control his empire from above, with a capital city of his own like Cloud Cuckoo Land. (As a cardinal rule, you can't build cities in the sky. He did control basically most of Asia, though).
Although Genghis could not create that ideal city in the sky, Genghis wants you of garnet to join Pi Zeta Tau, and become a member of a great society.
