It involves careful research to balance the different ritual components until you have something that is at minimum useful, but ideally also efficient. Felix is happy to share the rituals he knows, but his current selection is limited since he... wasn't planning to be cut off from his home world.

Can they be reverse-engineered?

To a degree, yes. But they are lacking part of the metaphorical vocabulary and Felix doesn't know how much they can advance without that. They might be stuck with mostly-protection oriented rituals, healing and sorcery gifts until contact with Felix's worlds is stabilized again.

And what are the risks from... rogue sorcerers?

The local kind of magic is significantly more versatile and flexible than sorcery. Stronger too. Felix doesn't think there is going to be a large quantity of these problems and less so a quantity that can't be solved with the resources they have at their disposal.

Okay. That sounds reasonable, then. They would like Felix and Kaede to be reachable and serve as consultants in the long term, and in the short term they'd like them to commit as much as they know to writing as possible.

Of course. They actually have done some of the writing already, but they are still working on making the notes useful (translating, formatting, confirming-that-they-are-accurate).

Very well. Will they come with the delegations, then?

Felix looks at Kaede for confirmation and - presuming an affirmative - nods.

Indeed. Off they go.

Felix is generally going to be quiet and hug Kaede a lot.

Well Naoh wants to know more about the magic, and the lady in robes, who finally introduces as Vamm, no title, has several questions about the other worlds.

Felix can answer their questions. Felix himself wants to know how open he should be about the entire sorcery business?

...maybe keep it quiet for now.

Yeah, that sounds reasonable. More magic-and-worlds questions?

Yes, lots of those.

Transport by wagon is slower and less comfortable than flight, but does give one more time to appreciate the scenery from below as the sun starts moving towards the horizon.

Scenery is an advantage, yes.

Where exactly are they going?

The capital.

Oh, what can they tell Felix about the capital?

Well what does he want to know?

General things, since he doesn't know what to ask. Maybe they could tell him about the place where they are going to stay?

At the embassy. It's rather pretty and spacious, actually a whole wing of the palace.

Isn't that a bit... much?

Why does he think so?

Well, it is not that he isn't grateful for the hospitality. He just doesn't think he merits a whole wing.
