Alas, nothing much about the Story Eater. It is a very mysterious entity indeed. However there would be at least one book or reference material about the Story Eater as collected from the realmofstories Any information from the game is available (and anything that's clearly written for OOC purposes/game mechanics would not be included like Drops and Hiatuses).

And there are restricted sections! But they are very well hidden so they wouldn't be discoverable. The owls will just be like Hoot knows...
