It came out of nowhere.
Felix was flying through the shattered skies, enjoying the sights of the many portals, taking the occasional selfie. Then the threads of energy formed between the portals. Felix almost flew straight into one. That kind of thing never happened. And the threads multiplied and filled the air until one...
...Felix now is somewhere else entirely no idea how he got here. While flying through the wilderness the pain starts and eventually culminates with a blood-covered pebble coming out of his mouth. Which was only supposed to happen if Felix was somewhere else so far that the magic that allows his immortality couldn't reach and the only possible place like this would be another universe entirely.
An hour, he gives himself that much time and uses it, but by then Felix decides that crying isn't useful anymore no matter how much he wants to.
Instead Felix searches for civilization, since he is going to stay in this world for the foreseeable future.
Well, steam power was in fact remarkably useful before the invention of more efficient technologies. In Felix's native worlds internal combustion and electrical engines are the ones used in large scale now.
...He doesn't understand the diagram. He is just a magical immortal weather-controller with conjuration powers from another world not an engineer, sorry.
"That's quite alright. Gentlement, let's not bother Felix over things he cannot control, we have plenty of books to study instead!"
"Edward will probably give you a knighthood for bringing knowledge to his shores anyway."
Edward being the king? Sorry, he didn't get acquainted with who is important here yet.
"Edward III is the king of the most important nation, that of England."
This starts a semi-good-natured political argument. Gren rolls her eyes. "This happens a lot, we'll have to let them get it out of their system."
"Nah, it's okay. I probably should be aware of the political map. If only so I don't step on anyone's toes."
"Good luck. Can you send me somewhere where I can learn who are the movers and shakers? Or was there something else I was supposed to do?"
"Maybe the captain would be able to tell you that, but she's, um. Probably busy. Lytee might know the political landscape too. She's actually our teleporter. Should I introduce you?
She walks along. "So, movers and shakers. The UDF is the most powerful entity in the world. Its top brass live and work in London. Most nations' kings kept many of their powers, but everyone has heavy taxes and other duties to the UDF now."
"Huh, how far reaching is the UDF? Both in terms of mobilizing witches and the associated nations?"
"There still isn't quite a Witch draft. It's just by far the best paying job most of us can get. And I know the Venetius Vi is king only in name now, as the UDF is working on mass evacuation of his territory. It's undefendable. I don't know a good quick answer to 'how much power do countries surrender to the UDF' other than 'lots'."
"I was thinking more in terms of... physical area of influence. Does the UDF reach other continents?
"Yeah. Most major countries signed on at least as a contributor. The Unity Mother formed the UDF - it's kind of legendary, how persuasive she was to everyone. Though we were fearing the Neuroi would overrun everything at the time."
"We got organized. Fought back. They used to be weaker than they are now, and there were less of them..."
"Ah, good thing. I wonder how much information I can get about them through dreamshaping."
"I have good reflexes, but I am not used to. Back home I could do well with just... the wings look really intimidating."
"If you're messing with anything connected to Neuroi you might have to do a lot of fighting very suddenly."
"Ah, yes. I don't think I am completely useless, but I haven't been in many life fire situations."
