Well, Hireshmont may have schismed, but I'm not sure there'd be a crusade. I mean hardly anyone protested when she was made Luminary, which at the time was essentially the Vice-Light. And judging by past history, when someone wants an Elder out of a position, they make a big fuss about it and try to get a Magistratum, or to get either the Regent or the Prophet involved to fix it. I mean no one launched crusades to get Allison out of power, and she was hated much more.
It was very different when she was chosen as Luminary.
A Magistratum might not have worked; but obviously that would have been step one.
