Have we officially ruled out Mask of Rahi Control? Since there's already an example of a nigh-identical scenario, I think it should be still be presented as a choice. Fair point; while the Brotherhood could have killed off people with the mask in their run-up to the Great Cataclysm (given the timespan, I would say it's close enough to that...), they wouldn't have necessarily had any reason to do so. Until someone else convinces Greg to retract his statement, it still isn't applicable.
