Nice work. I liked your use of discriptive language, which made it easy to visualize the setting, but at times the plot at times was a bit confusing. One thing you could improve on is the beginning dialog. Although it didn't really impact the plot, the guards' conversation didn't really fit the situation. Their actions greatly improved the believability of it, though. Overall I thought it was a great piece. I especially liked your use of repetition in the end. It was conclusive, but at the same time left room for more.
Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines, sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. — Mark Twain
