Why would they do that? Their enemies all seemed to be defeated and they were free to do whatever destructive nonsense they wanted. Sounds like an awful time to wipe your own memory. You've never tried to find someone on the other side of the house by following the sound of their voice, or played a game where you were blindfolded and had to navigate by what you heard? Same thing, but with strength of aura instead of volume of noise.
 * If that works, why did the Zamorakian mahjarrat not do it ages ago, when Zarosianism was wiped from the world?
 * Locating through hearing? Sounds interesting, elaborate.
