"Did it work?" asks Matilda.
"No, it's ialdae. I'm not surprised about that," says Matilda. "I think it makes sense that if your ialdae can see any other magic, it can see itself too. Jensal? Are you seeing it?"
She brings them all to the bottom of the world.
"Natural form, please, Ehail. And watch what I'm doing, you two."
She looks up at Ludei and Jensal.
"Did that make sense? Do you think you could do it too?"
"Okay. Well, we can go back to Ludei's house and get the next batch and you can watch me fix all those. I usually do it faster than that but it's the same set of steps every time."
Some of them catch ialdae. All of them have a little in them now, but a few are generating more.
Back to Ludei's house they go.
To the last shren house they go.
"There are," says Jensal, "lots of shrens who don't live in houses, because their parents took them home or they moved out as adults, but they'll be harder to assemble in batches. If you've got other demands on your time we can just learn to teleport and handle them in ones and twos ourselves as they trickle in."
"I am doing lots of things," says Matilda. "If you can fix the rest by yourself and don't have to wait for me, then that's good. But I should come back sometimes to see if you need anything and tell you if ialdae learns more things you might want to know about."
Matilda goes home. Matilda continues attending witchcraft lessons and being excited about witchcraft.
Her next ialdae lesson with Sarsia and Annei comes around. She shows up for it. "Did you hear that I taught ialdae a new thing?"
"Yes," she says. "But I don't think I could teach either of you to do it because it takes a lot of ialdae and I don't think you have enough. I can explain how I did it, though."
