From the introduction: You arrive in the world of the Librarian on the day that a new librarian is to be chosen. Normally this would be Flynn Carsen unless you change something. Watch out for the Serpent Brotherhood and all the other groups out there. This is not however a safe world to live in, as world ending threats happen twice a week before Friday. This is a world of magic, where artifacts of power, shapes the world and how people live in it. In the past few thousand years the Library collects them for storage but the world is populated with them.
