It's just as likely that an eastern realm will fall as a result of the upheaval caused by a massive migration. At least, I sure hope that happens.
I would be surprised if they didn't- its not like this kind of thing hasn't happened before on Dwilight. If I recall correctly Asylon was supposed to be a docile Caerwynian colony before Glaumring and his lot invaded and made it the Asylon we know today.
In any case I hope people realise that this is literally the best chance they have of finally breaking the SA and Lurian hegemonies that have long dominated the eastern continent. This kind of mass-migration is exactly what is needed to shake things up.
