In Hudson's heart of heart, he couldn't help but curse the stupidity of the Clergy. Even if they wanted to upset the Alpha Kingdom, this was not the way to do it.
Topping a kingdom is hard with external force alone, the best approach would still be to escalate internal disputes.
As Hudson thought about it, his headache increased, his original plan was no longer viable.
The Clergy might act foolishly once, but it does not mean that they will always remain so.
Decaying old nobles wouldn't willingly cede their interests, and newly rising Major Nobles wouldn't cease their expansion either; a clash was inevitable.
Post-war reshuffling of the Alpha Kingdom and an imminent intense battle were the best opportunities for the Clergy's intervention.
Overt interference won't be tolerated, but secretly supporting some nobles in creating trouble could be surprisingly effortless.
