I just finished watching this year's season of Game of Thrones and I noticed a weird thing. Books containing information about White walkers were placed in a restricted section.
But that just does not make any sense. In a restricted section I would expect books about making a wildfire, creating a deadly poison etc. (containing really dangerous knowledge), but not books considered a bunch of made up nonsense and fairy tales.
It might be because those books are very old, but in one episode, Sam is creating newer copies of books, so they might have publicly accessible copies of of these old books as well.
And if they are placed there because they were placed there pretty much from the beginning of the citadel (therefore placed there just because of tradition), shouldn't in this case the maesters take their content more seriously, since their predecessors valued information in those books as incredibly important?
No matter how I try to justify it, it just seems as a nonsensical plot device.
