After messing around with your lab’s brand new time machine, you and three of your friends accidentally send yourselves to the year 1222!  Not only are you in the Middle Ages, but you actually find yourselves in the middle of a war!  Unfortunately, your time machine was destroyed in the fighting and you are stuck in this era indefinitely.  After the nearby city was overtaken, you join the refugees in a search for the perfect location to start the new city.  Since you are obviously more sophisticated than most of the people living there, you and your friends are appointed to the task of setting up the new city layout, location, and defense mechanisms.  You can only use the limited tools of the time to devise a plan with a 3-D model of the city’s layout to present to the general.  Since most of the political leaders were killed in the battle, you also must set up a new governmental system and present that as well.  Make your decisions wisely; the fate of the city is in your hands.
