And since FR is best known to be an RPG setting besides it being the backdrop of Neverwinter Nights/Baldur's Gates/Drizzit etc, it is best on topic here, as most who play FR here have at least a passing interest in the PC games AND Books in that genre.
The question /might/ fit in litterature, but that would exclude the PC games from the possible sources. in scifi it might find a home, but how many experts there are experts in the game splatbooks, the pc games and the books? It is more likely o find the expert where the idea of the FR has its root: here.
