Changing your Campaign There can be situations when you need to change your current campaign. Maybe your friend is assigned to a different one or you just want to play with other people. Elder Scrolls Online allows you to leave your current campaign and join a different one of your choosing, so long as it isn't overpopulated.
Every character can change their campaign once for free. But, any other changes after this will cost you Alliance Points or Gold. This is a failsafe against players jumping from one campaign, to the other, every 5 minutes when they feel they aren't winning and will allow campaigns more stability.
You should also keep in mind that each campaign has its own leaderboard. It is unknown if your achievements will also be transferred to the new campaign, but we doubt it. So keep this in mind if you wish to switch campaigns.
There are also other restrictions in place for those who wish to choose a campaign. For example, you will not be able to join a campaign if you have a character in another faction assigned to it, this is to prevent spying.
Finally, If a player with Emperor status changes his or her home campaign, that player will lose the emperorship. This is to prevent several Emperors being in the same instance of Cyrodiil. That about covers all you need to know about how campaigns work within ESO, all you have to do now is join one and begin the fight for the ruby throne.
We as a guild will should stay in the one chosen for our faction by Fog, but until one has been chosen, I would just join a random one and then change when he is ready.
