Due to population differences between some of the highest and lowest populated PvP realms, the following Free Character Migration will be available from October 24th to 30th:

From: Crushridge, Frostmane, Grim Batol, Kazzak, Outland
To: Boulderfist, Jaedenar, Kor'gall

Please note that the migration may be closed at any time should a destination realm's population rise too high.
