"Anyway, I'll show you to the library," Arin said after seeing there were no more questions.  He led the group down a flight of stairs and showed them into a large room.  Every wall had large bookcases, filled with various tomes and scrolls, some with a few trinkets and other magical devices.  At the far end was a table with several vials of liquid on it, as well as few other alchemical tools.  A few books were scattered on the floor, but otherwise the room looked rather tidy.  "Feel free to examine whatever you want, but be careful.  There shouldn't be any really dangerous things here, but if you're careless you can still get hurt," he cautioned.
