And golems may be faster than you, so. It's not that big a risk, couple days, but still.
People are very surprised to see people appearing! Kib explains to curious bystanders that the snake thing got him, what ever happened to the snake thing, oh somebody chased it down with an industrial puppet and held it still and it was set on fire, oh is anyone else back yet? no nobody else is back yet who's this ridiculously tall person? this ridiculously tall person is from the place I landed, rejoice, being snake monstered is not necessarily fatal! and then they can be on their way to a bank and then Kib's teacher's house (the bank is on the way).
And here's the bank, which can in fact give Kib fiat currency for holy fuck that's a lot of diamonds man where'd you get them. (Kib's not saying.)
Kib packs up his notebooks and a few other things, explaining where he's going to be and why and hugging everybody goodbye and apparently he owes this co-prentice money so there's that settled and now it is time to buy Oh So Many Books.
Kib's not being selective. He has a lot of money to burn. "Do you want to see where you can get with the foreign language section? I'm not going to be able to translate it but we could get stuff from there anyway."
So they get some of everything. It's a nice big bookstore. Kib makes especially sure to load up on comprehensive servantmaking texts so he has references.
They don't have to transport it, just set it aside clearly and have it in mind as their cargo, assuming Eonwë was accurate.
The bookstore is willing to store them in the back set aside from the stock for a little extra money! The bookstore is so enthusiastic about all this money.
