"Okay." He leans over to dump the disassembled chain on a table, then sits with the book in his lap and dives in again, looking for the glass world.
What does he want? Something at a comfortable scale for her to move around in, with the outer glass panes completely absent so she can get into and out of it easily, and - better - not just made of glass - it should have real granite mountains and limestone hills, real sand in the deserts and ice in the glaciers and water in the lakes - he'll have to compromise on the vegetation, make grasslands and forests out of felt and cotton fluff, because he can't think of a sensible way to scale them -
The real sticking point is the way the continents hang inside the world. In the display, they were held up by wires or chains so fine he could barely see them, and that worked fine at that scale, but for his purposes he wants something Ranelin can explore without landmasses wobbling every which way whenever she touches them.
What if he just... insists that it should be the case that all the continents in the model world stay put by magic, purely because he said so? Can he do that?
It does not at first appear that he can do that. But he's at a loss for other things to do, so he keeps trying. Why shouldn't he be able to do this, he put a swoop in the book and swoops are full of magic that has to do with controlling how things move around, and the way he wants to control how these things move around is really simple, come on - what if he goes and picks apart the swoop, can he figure out which bits and pieces of its complex enchantments can be reassembled to work for this purpose -
It turns out that he can. An hour after he started trying, he surfaces from his trance to find himself looking at a metal frame in the shape of the world, filled with exceptionally detailed continents. It stands very stably on the round metal base he constructed, which is a good thing because it's nearly as tall as he is and he's not sure he could hold it upright by himself if he had to. He pokes a desert and discovers that the sand flows back into place as soon as his finger isn't in the way. The lakes are the same way, and the mist of Misty Falls hangs in a stubborn cloud, swirling this way or that when he waves his fingers through it but always returning to its appointed place.
