You order the Army to take a preemptive measure and shuffle the garrison officers and strengthen the loyal troops in the north.

Alas, this had only a minor effect. Even amongst the fresh troops and the newly appointed officers there were closeted Singularists who joined the local cliques and began scheming alongside their fellow cultists till there was an eruption.
A temple of the Pantheon was set aflame by an angry crowd of the Singularists in the city of Galad An Cawainn. Soon, minor teples across smaller settlements were set ablaze also, various military officers, minor nobles and city governors and village elders proclaiming their faith openly, most of them Singularists.
This movement, 'Sons of the One', number about nine thousand from all social classes and with some military veterans and supplies at hand. They proclaim they shall 'render the Pantheon obsolete' and install the One as the new and only chief god of Luathbas, and to do this they shall convince the Royal Family.
"Clearly we should think of the Kingdom, my Queen, and issue an edict of tolerance."
"No!" Booms the Marshal and props hands on his waist. "Let's send our Army to crush the rebel scum now that they openly dare question our way of life!" But despite all ideas and arguments, it's your decision that shall shape the future of Luathbas. And you decide to...
A) Issue an edict of tolerance in hopes of mending the relationship between Pantheonists and Singularists.
B) Send the Army to violently supress the religious uprising, cutting down all Singularists holding arms against you.
C) Convert to Singularism and revoke the rights and priviledges of the Pantheon to placate the armed horde.
D) Send envoy to the leaders of the Sons of the One and attempt to negotiate some sort of deal with them.
