They've tried that, already. It looks like magic just doesn't work through that door.

Sparkles is glad to provide samples of whatever.

Did Sadde check and see if sorcery works in this universe?

Lord greedily collects the samples.

Nope, they're waiting on Lord to be willing to run tests since it uses biological stuff as its fuel and their biology is apparently weird. See also, Exhibit A, the world beyond that door.

Interesting! But Temperance was thinking in terms of seeing if he could still use it himself.

Sadde shrugs and looks at Sparkles.

Yeah, I can still use it.

Great! Now Temperance wants to know...

They proceed to test things.

It turns out that sorcery works alright with local biology.

Local magic doesn't work through the doors, not even to just perceive things. They can't find local magic compatible worlds with the key. This means that anyone that goes through the door is effectively blind, but the doors can still be made useful with a minimum ingenuity.

You can wish using the crystalwishes but they can't repair themselves with the local version of light. This can be somewhat bypassed with the doors, but that has the risks associated with keeping the doors open.

Local metamagic is pretty terrible at understanding or interacting with foreign magic.

In that case, would Sparkles mind giving ludicrous amounts of lifeforce to people?

Sparkles was thinking exactly the same thing and has actually done that to everyone here as soon as Lord confirmed the safety of performing sorcery. They should all live to see ten thousand, now.

Nice, that should have some interesting effects on morale.

It should at least hold up until they can rescue the people captured.

Yes, meanwhile, would Sparkles mind building them a town? They designed something that takes advantage of their biokinesis and is low maintenance.

Sure, he can do that.

And the Captain has interacted with him enough that, honestly, this is unlikely to be some ploy. That is very much a very depressed pretty boy.

And pretty boy would like to bring up a topic of conversation they dropped while Sparkles was being depressing around them.

Yes, they should do that. The four of them gather in the same room.

"So."

Yes?

"...the three of you are absurdly attractive on about every single axis I can think of."

Well, what a coincidence. We think the same about you.

"And it kinda sounds too good to be true—like Isra did, actually—but that, er, Sparkles is me, that's obvious, and—erm—I don't know how to do this very well yet, and I feel like I might be disrespecting Isra for even thinking—"

I don't think Isra would agree with you. And we don't know how to do any interpersonal interactions well yet.

"I'm not sure what that's an argument for—or against."

I think it's an argument for being careful.

"There are many possible degrees of care."
