Now that you've mentioned this, it makes me wonder if they would come to Dwilight. My personal theory is that if they did, the Daimons on Dwilight would fight them -- if sufficiently motivated.
I will preface this by saying that this is me talking as a player, not as a dev, as I have not talked to Tom about it and will not for a variety of reasons.
That said...I think it's entirely possible that Dwilight or some other island will be Invaded if BT falls. It's not just for !@#$s and giggles that I have my two most prominent characters talking about it.
