Out there among the cosmos is a plane made entirely of knowledge. Every individual life, every word written, every thought conceived, all documented and recorded, made available for anyone to access. The Guardians of this realm (They prefer the term Librarians) do not discriminate. Any creature of any alignment or disposition is allowed access to this knowledge. There are forests of fairy tales, oceans of reference books, Entire towns made out of spell scrolls, even an island dedicated to the proper preparation and cooking of shellfish! Its a scholar's dream...if you can find a way to get there.
Of course, there are a few things that, if made accessible to anyone, could prove catastrophic.The Librarians guard this information with their lives, and have placed several powerful defenses to deter overly-inquisitive minds.
Recently, however, the defenses, which have been in place for millenia, have begun to fail. Something is trying to break in, and the Librarians must find a means to stop them. Are you the adventurers they are seeking? Only time will tell...
