See the Expansion Maps page for orientation of the different areas.  For your convenience, the game map has been separated into four quadrants. Take note of the "quadrant"/location next to the listing, and the link will take you to the main Expansion Maps page. Choose the tab for the specific quadrant on the maps page for a closer view.  Expansion areas that open Timed Expansion Challenge quests when unlocked are marked with TEC.

Each of these lists can be sorted alpha-numerically using the arrows on the column headings.
