Coalesced Realm, also know sometimes as cross-realm zone, is a temporary joining of populations from different Realms in the same world zone. Coalesced Realm is also a label that appears in a player character tool-tip to identify the target as from a another realm. A player who is coalesced is only temporarily joined in the current zone, primarily to fill what would have been a lowly populated zone. A Coalesced Realms differs from Connected Realms, or 'Virtual Realm', in that it is temporary and per-zone, much like as in battlegrounds or other types of instances.
