@Gustav, not to be mean or anything, but I really don't think you threatening to leave is going to make much of a difference.
I don't like the Daimons/Zuma at all myself, I feel they add little to the atmosphere other than a looming sense of doom for those nearby, but they're here and they won't be going away any time soon, so I deal with them as best I can. They are not a gigantic wrecking ball destroying realms at random. In fact they have yet to destroy a single realm, if I'm not mistaken. But they are very, very dangerous, and if you happen to have settled lands on their borders, well, then you have to deal with that whether you like it or not. There's plenty of realms who are not affected by them (or maybe a teensie bit) so it's not like they have the entire island by the balls.
@GoldPanda, not everyone talking to the Zuma does so via Garret, you know. There are people who speak to Haktoo directly.
