This room, much like the archives, houses old threads, but not threads that have died, outright so much as they have simply been put on hold.
The small room, not much larger than a large closet, simply contains a filing cabinet, only one or two shelves of which were used. There is less dust and no mildew smell, unlike the archives and there seems as though there's been a bit more traffic (or at least more attention paid) than the archives.
