I wonder how much Elidibus' notion in 2.1 is tied into this - that if we knew the true power of the Echo, there would be no disagreement with the ascians. Is Elidibus powerful enough to psuedo-temper those around him?
What about Minfilia/Word of the Mother - she is doing the equivilent job for Hydaelen in the 1st that Elidibus is doing for Zodiark in the Source, right?

Do we need to re-examine all the Echo lore in light of 4.0?
