The two halves of the city still maintained trade, but as it became harder and harder to travel between them over the centuries, each developed its own language and customs. They became two places united by history, architecture, and geography, but separated by everything else.

This architectural dream, titled "Rocky Mountains," comes from the mind of artist Andrée Wallin. You can see more of Wallin's work at his portfolio site, on deviantART, and on Facebook.
