The Library Arcanium is the current headquarters for the Society.
Overview
The Library Arcanium is the greatest storehouse of all knowledge in existence. Its various rooms are filled books that cover ever sort of topic imaginable-various magics and martial arts, literature, history, mathetmatics, space flight, religion and many more. One could spend their entire lifetime in a single room and still not read everything within it...
Little is known about the Library, but apparently, the Library has existed since the dawn of recorded knowledge and must have a Libarian in order to exist. There may only be one Librarian at a time. How one becomes the Librarian, is uknown, as none of the Librarians have ever revealed it and it is a secret that not even the Library itself knows.
Because of its vast collection of knowledge, some of which is very dangerous to even trained minds, the Libray lies in trandsdimensional space (Thus, there are no windows or doors that lead "out" of the Library. Similarily, trying to bust through walls will only lead one to another room), unaccessible by outside means for the most part. Though there are a few powerful entities (gods, goddesses, angels, authors, etc.) who could enter the Library, they are so powerful that they have no need of the knowledge within its walls. Thus, the Library remains a impregnable fortress to many who desire its treasures.
The Librarian is allowed to enter and leave whenever they wish and are allowed to bring others with them. Currently, Agents of the Anti-Cliché and Mary-Sue Elimination Society posses Portal Guns that allow them to open a portal between their current location and the Library. However, these portals have been altered to let only registered members pass through them. An unregistered person attempting to do so will be thrown back violently and zapped with lightning. Repeated attempts will result in the same, plus a loud raspberry.
Also, it seems to be that the Librarian can "create" a small verison of the Library on various worlds. These smaller Libraries contain usually information on a specific topic (magic, history, etc) and appear in worlds where a hero or protagonist is need of direction or guidance. The current Librarian will always be the attening librarian at these Libraries and generally know just what to tell or help the hero with in order to progress things. In appearence, this Libraries tend to look like the building style around them, though they always appear to be a bit rundown and ramshackle compared to their surroundings.
Once in the Library, navigating can be quite a challenge. With an endless supply of rooms of varying shapes and sizes, not to mention arcitechure (the room on Greek mythology, for example, is shapped like a Greek temple), one can get quite lost very easily and if they wandered for a hundred years, probably never come across the same room twice. Only the Librarian can navigate the Library easily, as they naturally know where everything is.
Luckily for vistors, in recent years, the Library's size more or less remained the same and the arrangement of rooms remained constant. Furthermore, the labels for each room and its contents have appeared, making locating and finding things much easier. There is an index located in each room so that one might find a particular book quickly. There is also a master index located in the Librarian's office. (His office is never in the same place twice and hard to locate, especially if he's napping...)
There are some books, however, that too dangerous be availible to vistors and these books are kept in a private room attatched to the Librarian's office. There is no lock and no hinges and it is impossible to attempt to breach the door with magic, brute force or any other means. Only the Librarian knows how to open this door and he has ferociously resisted attempts to make him open it.
