Many times you will want to join an alliance and you’ll see that the alliance is based in one region of Evony. This is because a region is a small section of the map maybe 100 x 100 miles or so. If all the members are in this area it will make it easier to assist one another in battles.
Usually your Alliance will want you to teleport to their region of Evony. This is because you will be closer to your allies and they will be better able to help you. If you are 300 miles away no one will be able to help you!
You get two city teleporters. The first is in your “newbie gift box” that everyone gets when they join. The second is in the “lords gift box” that you get when your town hall reaches level 4. A city teleporter helps you because it allows you to move one city to a new region of the map.
(See the city teleporter for more info on how to teleport your city.)
