There aren't that many things he wants in this world.
What he really wants, above all else, is his family back.
So he asks.
"My uncle has been catatonic for nearly five years. Can you help him?"
"Are they all like this? Who decided to go for broke on the fight cutscenes?"
"They are all like this, modulo themes and strategies. It's absolutely wasteful. They could probably handle major infra-structure projects or heal dozens with this sort of power."
Fenris obviously doesn't care for the Witch-Queens.
"It's pretty cool. Must be good for PR. How much of their queenliness is that and how much is the magic?"
"Well, it is a nice way to show that they have power to spare - witchcraft runs on a fuel of sorts. I am not sure I understood the question?"
"Why are there witch queens, do you not have a government? Are there witch cops? Witch lawyers?'
After he's done insisting Kato eat some cookies, he decides to flop on the couch.
"We have standard regular form of governments, it is just so happens there are witch-queens in addition to those. They get to be queens because they can throw that kind of power around. It makes easy for people to obey you."
"You guys have magic too, couldn't you just- become dreamshaper kings?"
"We are likely to be stronger than Witch-Queens, but are not sure. We are also not the only dreamshapers back home but the others are various flavor of traumatized. Mostly we have been trying to stay safe and secure ourselves, before making any serious move."
"I am sort of afraid he might make mistakes like I - I guess it's we - made before. But he should be fine..."
"I was thinking about the other Felix. If he's alone in my world...I just hope he's okay."
"Me too. I think the two here have mostly... trying to focus on working so they don't think about it."
"Are things still going on back there? It wouldn't kill them to wait for you to get back..."
"Can I do something to help you? I should be able to make the work go faster somehow."
"Things are still moving, but it's okay, we all knew what we signed up for when moved between worlds."
Scott doesn't really have to, but if he wants to help Kato can offer a couple of ideas.
"We are still recovering and trying to consolidate and patch up vulnerabilities. Which mostly manifests in the form of traumatized dreamshapers. While simultaneously trying to use dreamshaping-conjured things to get a subtle influence. ...We have been focusing on getting custody of our sister from our grandparents."
"Why are dreamshapers so dangerous? Is there a manual on you guys?"
Fenris does have some notes, which he shows them to Stiles.
The minimum dreamshaper power set includes the ability to create a pocket dimension and portals to-and-from there. This is usually accompanied by some sort of matter generation such that they create terrain to fill in the pocket dimension. This is a process of creation and dreamshapers typically can't change their dimension's environment. And it can only be done while asleep. Dreamshapers lose the ability to dream the normal way.
The pocket dimension "coexists" with the outside world such that one could describe it as occupying the same three dimensional coordinates, but being displaced in a "fourth" dimension. Meaning that if you can see through dimensions (there is a magical glass that allows this) you would observe people and things overlapping each other, even though they wouldn't be interacting in any other way. For the same reason, if one were to enter through a portal, walk a mile and then exit through another portal, they would find themselves the same distance and direction from their starting point.
However, dreamshaping is very idiosyncratic and even the above rules can be bent or defied. Some dimensions still have a relationship with regular three dimensional space, but they are internally warped or fluid. Some dreamshapers have wildly variable levels of control over the contents of their dimensions and portal creation (including the ability to shape the terrain as they want). Some dreamshapers have the power to project an "avatar" into the dimension while they are asleep.
Furthermore, dimensions have other unique-often-magical traits. They might have ambient effects, produce unique species, materials, objects or people... it varies wildly. It varies from harmlessness (zones of lower gravity) to dangerous (shapeshifting monsters), not to mention apparently random, like a dimension that gives you a knife when you visit it for the first time and teleports it back to your hand in the subsequent visits.
"So, in short. With minimum preparation any dreamshaper could invade anywhere and a good chunk of them could contribute other things like weapons or mind control. Can you imagine the chaos an ill-intentioned dreamshaper could wreak? Or even just a misguided one?"
"I think I'm getting the picture. Would keeping them awake make them easier to handle?"
"Somewhat, it does mean that they can't work their dreamshaping and they might be too tired to direct the dreamshaping once they do fall asleep, but that isn't sustainable. Not to mention they might be in a spot where they can direct their dreamshaping but not lucid enough to consider the consequences of their actions. Like creating explosives as a means to free themselves."
