Inric finds Tiero sitting on a bench which has been dragged in from somewhere else in the library, probably by Jakin. He is concentrating on some kind of complicated knotwork, and doesn't notice Inric's approach until he speaks.
"You may read any of the books in the library."
Tiero starts and looks up. "Uh. Truly?"
"That is what they are here for. Do you have everything you need here?"
"Oh, um. Yes. I think so."
"If you find otherwise, ask without obligation. As I said before, the most important thing is to stop them damaging the books."
