Virid's and Shima's leaders asked them to do it. I know one other leader who made the same order. So I think we can assume at least one of the murders each week is because a leader told them to.

I know some people know this already and others are are starting to suspect it. The last thing we need is for everyone to start turning on the leaders, though. They don't want to to make these requests and they're trying to help us. They're just limited in what they can do right now.

As for how to fix the Realm... we've known part of that answer since the beginning. We collect nova so the Realm can recover. And now, we know there's a monster draining nova so we need to stop that, too. It's possible some leaders know more than others... each one seems to have their own "area" of knowledge but they can't discuss it freely without revealing who is on their team which, as you know, strains the Realm, too.
