That would require breaking several alliances and Federations to be possible though. While as players we can look at Morek and say, move there, convincing realms already at war to change tact and support their fledging allies, whom they have invested troops and time into establishing in their current location, to take territory off a nominally allied realm instead is probably not going to happen.
If only there were realms now fighting Luria that had a past history of fighting Morek at any opportunity...
