A game account management feature that allows you to move some characters from one Realm to another. Only some realms are eligible for movement. Eligible realms are announced periodically by Blizzard. All transfers are between similar servers: PvP to PvP, RP to RP, Normal (PvE) to Normal, and presumably RP-PvP to RP-PvP.
