"My scry has run out. But I think this is it. Look at that, think it's a key?"

"I don't think so?" Squint. "It looks spherical? Do you think you could grab it?"

"I could. Think it's worth a dot of magic to try and grab it without swimming down there?"

"Maybe? I don't know how else to find the witch."

"I wanna save my points if I can."

He takes off his boots, tests the temperature of the water, and then dives down and grabs for the shiny thing!

The shiny thing is easily grabable!

It's a bell with the words "Ring Me" in bold letters and it's attached to a long thin chain which extends deep into the lake.

He pulls it to the surface and gets back on the lily pads before investigating it. "Ring me? What's that mean?"

"That's a bell... you shake it and it rings a sound."

"Huh."

He shakes it.

The bell rings much louder than an object that size should ring. The water becomes agitated and then bubbles start coming to the surface.

A flag emerges, followed by a pointy roof and then the main body of a stone tower. It floats in the water right at door level.

A girl with green hair in a black dress opens the door. There is no sign that she was affected by her home being underwater. "Yes? How can I help you?"

"Hi! I have weird otherworldly magic! I hear that's interesting! And local magic is interesting too, probably. So here I am."

"Ooh!Come inside!" She ushers them in. "What kind of magic? How did you get it? What can you do with it?"

"I'm gonna call it points. I got it by existing! All kinds of things if I work out how to do them with, like, math and stuff first. I did a scry to look for your house knowing just that there was a witch with a moving house, and what you look like and your name. If there were any other dark skinned witches it might have gotten confused - names don't work perfectly. I can dry myself off with it too," He waves one sopping wet arm around, "But points don't come back for a whole day if you use them so I try to save 'em whenever I can."

She twitches her nose. NIco is suddenly dry, though his hair is kind of terrible fluffy. "Oooh, can you do anything sufficiently specified with it? Oh, where are my manners. Would you like anything? Water? Juice? Tea? Biscuits?"

"Aaah, casual display of power, oh no."

"-Food and juice would be nice, though. But mostly I wanna talk about magic. I can probably do anything sufficiently specified eventually? The limits aren't super well understood to be honest. Some things definitely take more than others. Some things take a point permanently. Those're very expensive."

"This is my house. My bewitched house, I can do a lot within it's walls," she explains in answer to his uneasy at her magic." She says this while spinning her left hand, which might be related to the juice and plate of cookies floating towards them.

The jar, the glasses, the plate and even the cookies are all mismatched. No two alike.

Adam sniffs some of the cookies suspiciously, but decides to eat anyway.

"Seems like a nice place to live. I think I want a bewitched truck. Or boat. How's the magic here work anyway? I read a tenth of a book about it yesterday but it didn't make too much sense."

Nico also takes snacks. 

They taste as randomly as they look, but each one tastes good. One is filled with warm honey.

"If it wasn't a book about using magic, then I guess it wouldn't. Most of non-innate magic is about tapping into an existent magic source and shaping it through materials, incantations and geometry. You would have more luck with a sufficiently long boat. Magic likes straight lines and circles. This house, for example, is kinda like a magical staff, except much larger. Which is how I can do my small tricks."

These are yummy.

"I could do it myself with enough time probably. But fair enough. Geometry, huh? Do cylinders count for circles?"

"If they are short enough they count as circles, if they are too long they count as lines. Though there is in-between point where they count as both, which can be versatile but often leads to the magical effects being weakened. How would you go about making a specific place grant telekinesis to a specific person?"

"...I think making an object that a specific person can telekinesis would be easier? I'd have to think about it more."

"Because your magic has an easier time recognizing and anchoring to objects than to places?"
