Preaching unrest in Aurvandil would be the office of the Maddening... but preaching unrest would have little effect if there weren't already a fair number of Astroists in the regions.

And really, neither is going to happen without either the permission of Aurvandil, or the support of Astroist military forces. So there's that.
