Horn's attention to the Saint Father's Association is not because he was idle, but because there was indeed a demand.
As the saying goes, "No destruction, no creation," not only does it speak of future plans to destroy the Thousand River Valley Church, just destroying the church in Langsande County would create a significant power vacuum.
In a power vacuum, if Horn doesn't send someone to take control, it would be other, unknown people who would take control.
Within the Empire, especially in Leia Kingdom's Thousand River Valley, entrusting grassroots governance to the church is a commonplace affair.
At the moment, Horn doesn't have enough intellectuals to help him manage these grassroots affairs.
So, either appoint members of the Saint Father's Association primarily, paired with some of the old priests to handle it, or assign people from the Saint Father's Association as an inspection team to oversee the actions of the old priests.
