Some rules mediums claim to know what Gygax meant by a particular rule...they can just call him up and ask him, it seems.A Rules Medium is, of course, the Seer who looks beyond the RAW and into the deep aether of the norms and customs of the game.
A truly powerful Rules Medium can even talk with rules that have been long dead and tell you how those rules would apply today!
