"I suspect blanks need larger diagrams, and a few more weird nested clauses in the section on midforms."

"Yeah, I guess that makes sense."

"Fortunately we live in the age of the photocopy. Or, lately, the large collection of photocopies taped together."

"They probably did inventive things with stamps back in the day."

"Yeah. Oh man, once the masquerade is down I bet someone will invent software that makes it feasible to design diagrams in an editor and print them off. And that might actually count as a new one like a stamp does rather than needing tracing like a photocopy."

"Why would that count?"

"Because it's going from a digital image to a physical one with no pre-existing physical one. If that doesn't work, maybe an equivalent of movable type would, but that would be harder to design."

"Huh, that might matter, that's a good point. Of course, you could test that with a scanner and like... erasing a rune in an image editor, then printing it out again."

"Oooh, yeah, scan one with an extra rune and take it out to make the diagram I want. I'll give it a shot next time I'm stuck on medallions." She writes down "scan+print" on the paper with the phone number.

"Anytime."

"Having someone to talk to and get ideas from is nice. Speaking of ideas, how did you manage walking through walls without falling through the floor? I can think of ideas but none it sounds safe to test." 

"Naive use of the word 'wall' worked."

"Oh, nice! Does that mean you can't go through trees or doors unless you special-case them?" (And how have you not died yet, doing stuff like that without dragonish cheating?)

"I included doors but yeah I'd have to change the incantation to do trees."

"That makes sense. I can't think of a reason you'd need to walk through a tree."

"Being chased through a forest?"

"True. But hey, now you can teleport. Which reminds me, I didn't explain the safety features. It brings your clothes and things you're holding, and if your destination is occupied by something other than air it just doesn't go. It doesn't stop you from appearing in midair, since we both have wings and appearing well off the ground is a good way to avoid obstacles."

"How does it define things I'm holding?"

"If you're fully supporting it instead of part of it touching the ground or a table or something. Shoes work fine though, they count as clothes."

"Okay, so no hooking my arm through a backpack and not fully lifting it."

"Basically, yeah. If you expect to need to move a lot of cargo I can work on a version two that will bring any container your hand is touching and its contents, or something."

"It's not a need I specifically anticipate but it's good to know the parameters."

Nod. "I don't think I'm leaving anything out . . . Oh, do you want the latitude and longitude of the empty side of my garage, as a convenient out-of-the-way location in Seattle? You can overwrite it if you end up needing twenty non-Seattle locations."

"Couldn't hurt."

So Margaret walks Bella through adding the coordinates as one of the keywords on her necklace. "Alright, I think that's everything before I head home and get back to work on the medallions?"
