How do I find my alliance so I can transport near them?

Check in the world map and tap the pin icon in the lower left to view the entire state. If you are R2 or above you will be able to see pins for all of the alliance member. If you are R1 you will only see the yellow pin of your leader. You can also ask in the alliance chat for a good location to move to.

If you are new to the alliance then the leader or R4 members may be able to send you an alliance teleport invitation that will let you move near to them for free.
