And now they get to test the cool local magic and how it interacts with theirs! Does Marit have any experiments he wants to start with or should they just start listing ideas?

He wants to get them a proper list of the wizard and cleric spells widely known at each circle, in more detail than the talk he gave them on the way over, so they can notice if there's anything they have a wildly more efficient spell for. A lot of wizard spells are improved by some other kind of spellcaster having a much more efficient way to do it and then wizards imitating. 

He also wants to watch them cast some spells with his own magic detection up, see if he can figure out what they're doing, and he can show them more of what he's doing. 

How about he puts up his magic detection and watches Abigail give him their kind of magic detection and then they do some simple things so he can watch both ways?

(Kevin has been standing on one foot for the past while, now that they have enough room in their mana storage for it to be worth building more. Also because he's antsy.)

Sure! He'll cast Detect Magic. There's better magic observation spells than that but he doesn't have the available spell slots today since he did the Share Language.

They can do this again tomorrow if it looks like it would help. Now he can watch her chanting in Greek to give him a very synaesthetic and vibes-based arcane sight. It shows most their jewelry as passively and fixedly magical and their bodies and one armband each as much more actively and potentially magical.

- weird. Does his body look magical too or is that just theirs.

His body doesn't but his spellbook does. And so does his headband, though that may be harder to notice what with it being on his head.

"Huh. To your magic, though not to mine, all of you look very magical in a respect in which I am not myself magical."

"Probably related to how you can't store our kind of mana. If I was totally out I'd show up a lot less but not none." She casts a little floating light spell so he can watch mana flow from her body into the light and dissipate from there.

"Huh. I wonder if sorcerers from our world look to you like they're - storing mana - in the relevant way, or not. And I wonder if magical beasts and outsiders glow." He'll cast his own floating light spell, for comparison: after he casts it he catches the magic in the air and tucks it away back in his spellbook so as not to expend it.

"Did you just recycle that spell? That's really cool! We can't do that at all."

"Oh! Yeah, cantrips are spells we've gotten down to a simple enough structure it holds together during casting and you can learn to catch it and keep it and cast it all day. They're really useful. Magic detection is one, and light, and laundry, and cooling liquids."

"Infinite laundry spells," she says enviously. "Wow." (All four Bostonians are pretty disgusting by modern Earth standards and sufficiently used to this that they're barely aware of it when it's not being brought to their attention.)

"You want me to show you that one?" Marit does not himself conform to modern Earth hygiene standards either because of having been raised in a society that is not modern Earth.

"Sure!" Abigail at least remembers what it was like to shower and put on new clothes every day even if she's long since gotten used to not that. She does the magic-seeing spell for Franklin too so he can watch the cantrip get recycled.

Then he'll prestidigitation all their clothes and selves! It kinda tickles.

Nifty and luxurious!

Intellectually fascinating!

Marcy goes from book-fugue to high alert with a shield up and her knife in her hand and then back to book-fugue in the space of a round.

Marit takes an apologetic step back and brings the palms of his hands together in front of him in the local style for 'I'm visibly not taking spellcasting actions' and then goes back to prestidigitating. 

"Sorry about that; I should've warned her. We won't attack anyone who looks human and isn't really obviously attacking us first. Unless you surprise one of us in our sleep."

"I will be sure not to do that. If you do attack people, priests have very good healing, just try to get one as fast as possible."

She nods. "Got it. And we'll work on retuning our instincts to be the right ones for this place."

"I mean, I don't know how much retuning you even need to do. I guess in the fort you're mostly pretty safe. It's tough to make a place totally impenetrable to demons but it's not that hard to make it not worth their while; they're mostly trying to sneak past us to go eat innocent people. There've been a couple occasions where they've done a coordinated infiltration effort on a fort - not Traves, but there's lots of forts - but that usually looks like lots of mind control, more than something sneaking up to eat you while you're in a workroom."
