When Iobel hears about the new world's details, and in particular her new alt's powers, she invites him over. It would have knock-on economic effects that they can't handle if he made everything that pops into her head, but crops that usually have higher yields and have been affected by this year's weather conditions can be added to the palace granary, especially pricey ones they can export or would otherwise have to import. He can make a little well-disguised generator so that they don't have to snake power cables as well as Internet ones into Chamomile through their portals. He can be conducted invisibly to various locations around the country (in a little flying vehicle he makes; she's going through a lot of invisibility scrolls to conserve her binder spells) and induced to add water here and trees there and stone to that quarry and nutrients to that low-quality soil. They are out almost all day doing that, flying high so they can be mistaken for a a bird when the short-lived invisibility wears off. And then they come back and Iobel looks through her notes and starts listing lost hexes and mythical spells.

She wants their charts.

And Cam can make them.
