JRoss, I will make a promise: I will try to find an affordable set of Firefly/Serenity DVDs (I have no access to normal online viewing sites), watch them, and then come back and give my opinion on this issue. But please keep in mind the Other Memory lives accessible to Leto and Ghanima in Children of Dune
and the whole concept of the mohalata
. The Bene Gesserit had roots going back tens of millennia.
