what im currently wondering is if the Rune Wars themselves are still canon...the reason the IOW came into existence was because the Rune Wars were so destructive so dangerous to the integrity of the world that summoners from all city states banded together to stop it.
Since the IOW no longer exists...that means there was nothing to stop the rune wars....which would only matter if the Rune Wars themselves were still canon.
Cant really back this up with anything, but the way I see the current climate in Valoran is basically a cold war....no major engagements are occurring currently, mostly minor clashes and trade disputes (Kalamanda could im thinking would be retconed into something like this, which Swain used to set up his plan).
