I had a dream (which I'm using as a blueprint for this idea) in which Ur held a magical beehive region (complete with flowing honey and giant bees!) This region's "map" was uncharted, or rather, unchartable. The streets were set up on hexagonal tiles which would rotate periodically (similar to Hogwartz's moving staircases.) This makes getting to the middle of the hive very difficult, and sometimes frustrating. But at the middle of the hive holds a treasure to behold - as much honey as you can carry! Before you dip your empty jars into the honey pit, however you must appease the Queen! The queen's quest sends you back out of the hive on a mighty journey across Ur to retrieve her crown.
Maze region? Honey hive? What say you?
