Here is a list of in-game organizations that players may officially join in addition to being part of an alliance. Unless otherwise noted, you may only be a part of one organization. Which organization you are a part of should be listed under the affiliation section of your wiki, next to your alliance. You may leave an organization at any time to join a different one, but if you do, you can never return to the one you left.

Keep in mind that organization benefits may be expanded upon in the future.
