And SCAG was only sort of 1st-party--it was licensed out to Green Ronin in the first place. So my guess is that they're just going to disavow any knowledge of such things. Wall of the Faithless? What ever are you talking about? No such thing has ever existed. Right guys?
Earlier in the thread I said the reason the Wall got brought back was bad copypasta, and this change pretty much confirms that reasoning. Whoever wrote SCAG simply wasn't up on the - really rather obscure - fact that the Wall had been changed/eliminated two editions back and simply slotted in the earlier version from memory or an early source.
