For those of you wondering:
War will last until July 19th. The realm with most TOed regions will keep the opponent's region (For Perdan - they will keep Woolton, For Vix it will be Dimwood). All other conquered regions will be returned.
I must say this war is very enjoyable. Members of both realms know that this won't lead to a total destruction so everyone seems to be relaxed.
Vix also put new people as marshals to help them get into the game better.
