Direct Descent

Earth has become a library planet for thousands of years a bastion of both useful and useless knowledge-esoterica of all types history science politics-gathered by teams of pack rats who scour the galaxy for any scrap of information. Knowledge is power knowledge is wealth and knowledge can be a weapon. As powerful dictators come and go over the course of history the cadre of dedicated librarians is sworn to obey the lawful government . . . and use their wits to protect the treasure trove of knowledge they have collected over the millennia.
