Yoink! Definitely anti-magic, and something about is less structured than a wizard's spells, but also more flexible.

"Yeah, that worked. It almost feels like I should be able to do something with it?"

"Yeah, you can put your life energy into it to create a sphere of anti-magic around you." He gestures towards the yoinked crystal. "Let me see if it feels different?"

"Yeah, here," he passes it back. "How's the life energy thing work?"

"The regular way is just to use your connection with the crystal to push the energy into it, which would be intuitive, are you feeling anything like that?"

He inspects the crystal, extending the fingertips to connect to it. "Weird."

"Yeah, just - life energy's the kind of thing it's a good idea to be careful with, at least where I'm from." He shrugs, and pushes just a tiny bit in.

"Using the crystals is uncomfortable enough that it's hard for us not to be careful, but excellent point."

Just the tiny bit of life energy is enough to "inflate" the magical structure and expand it like a hot air balloon. It covers the entirety of  the space between Wilston and Henry, plus a few inches. There is a sense that the structure is flexible and occupying that much area makes it... weak, like this wouldn't stop any magic that isn't a cantrip, just diminish slightly.

And if he puts in a little more?

He can feel the fuel moving through from the center of the anti-magic sphere like a wave, then reaching the outer wall and adding a couple more inches.

Huh. Can he... squish it closer?

The bubble trembles... but fails to change.

"What are you trying to do?"

"It looks like it'd be stronger if it wasn't as big? So I'm trying to make it smaller. I'll get it in a minute, probably."

"Ah," he nods. "Might be easier if you pick a specific point instead to direct into, instead of working on the whole thing? That is what is like for me."

Hm, like this? No.... Like this? Not quite... How about this?

No... nope! And... now that works! The anti-magic becomes less uniform in shape and effect, but clearly more efficient. This could be used as quite a decent shield.

Nice. "I'd be interested in taking one of those home if you're up for selling them. Assuming the effect sticks around."

"I don't mind. I am hanging out here for that purpose, actually. And the effects stay, assuming tapping them for magic doesn't render them powerless."

"It shouldn't. Like, I'll want to see what that one's looking like in ten minutes," he nods at the crystal he tapped earlier, "but it never does at home. Anyway, what would you want for one?"

"Learning spellthievery would be good. Things you can't buy from Bar would also be good. If you world is extremely nice to live in, I might know some people who wouldn't mind moving out of the island we are stuck in."

"Oh, you need to talk to Tarstil - do you see him around? Human, heavy, tall, short beard, grey robes? He was going for a walk out back but he might have come back in."

Henry stands up to look around and try to remember if he has seen anyone fitting that description. It isn't at all weird given Milliways typical patrons.

He doesn't seem to be around.

Henry shakes his head. "Does he have any particular expertise on the topic?"

"Yeah, he's a cleric of Fharlanghn, our god of travel. Not, like, a very good one, magically, more of a wizard, but it's still his job to help people who're stuck places."

"Oh, that sounds helpful. Is his - and for the matters yours - magic good at transporting large objects?"
