Well it would be an amusing way to settle which island is the next one to get smoked, right? Why, whichever one is foolish enough to allow someone to make use of some portal stones. A little tinkering to make sure they start showing up more often (and that they actually do something sinister when activated), and your pot is on to boil...
Well, yes and no. I wouldn't determine which continent gets targeted this way, personally, as one player should not get to decide over such matters for everyone. For example, I would have great pleasure to go and do that on the EC, but that wouldn't be fair to the people who actually invested themselves on that island for all this time.
I would have a global vote to select which continent, and take the continent with the highest approval rate as the next target. However, leaving the timing of the next invasion to adventurers sounds fine.
