Works for me!

Great, I'll be there.

She is there at 11 AM on Saturday, with the various bracelets (all disenchanted).

Brenda takes them back and walks her through the simple HTML on the site.

She's a quick study.

"I wonder what I should work on next. Maybe healing, but that's potentially harder to turn into an item."

"Is it? How come?"

"More of the flexibility is in the incantation, is the sense I get. And casting the same spell a bunch of times does more than casting it once, but I don't know if activating an artifact a bunch of times would do the same thing. I could try it."

"Huh. I don't know what to make of that."

"Yeah. Also I'd be worried about unexpected behavior, I've never healed anything except bugs and a couple of cats and dogs and there are just so many weird things that can happen with biology."

"Where did you get cats and dogs that needed to be healed?" asks Brenda dubiously.

"My mom's a vet, I snuck into her office and healed a couple of broken bones and stuff. I tried on bugs and a little cut on myself first. All the cats and dogs ended up better off than they started or I wouldn't even be thinking of doing more healing, promise."

"I dunno, they might - get cancer in two years or something."

"Yeah. So you can see why I don't really want to do healing items. Lots of places on the internet sell luck charms but I don't know if any of them work. I could try making a Bag of Holding, that would be cool."

"That would be really cool - is that really something you could do? Some Avalons are bigger on the inside, but that's different from a bag."

"One of my textbooks has something described as a 'space warping spell', but I haven't analyzed it yet, so, maybe? It's more of a research direction than a defined project, it might be I can only make people's closets bigger on the inside and not do something portable, or whatever."

"There might be a reason why Avalons are bigger inside but the houses aren't."

"Yeah, maybe you need a certain minimum volume to start with. Or it does something to the walls so if you did it to a house it would make it harder to have plumbing and ventilation and things."

"What I meant was maybe you can't put them inside each other."

"Ohhhhh, yeah, that'd do it. Better try putting a small bag of holding in a bigger bag of holding--or better yet, throwing one into the other from a nice long distance--before bringing anything to the Avalon. And looking in the library for anything on space-expanding magic before any of that, so if anybody bothered to write it down I can find out that way."

"Yeah, you need to be really careful with anything that might wreck the Avalon," nods Brenda.

"Yeah, I'm definitely going to be starting with, like, grocery bags. Something that I don't care if it catches on fire or gets sucked into another dimension or both. I really want a bag of holding but space-warping sounds weird."

"Sucked into another dimension? Could that happen?"

"Probably not, since it's just warping the space in this dimension, but part of doing magic--or anything else--safely is thinking about weird things that could go wrong and then making sure they don't."

"How do you prevent things from being sucked into other dimensions?"

"Checking the spell over carefully to make sure it doesn't have any unexpected bits, and making the incantation very clear about how I want it to work."

"I guess that's all you can do."
