IMO the Chancellor pushing aside the Unity isn't the main error in Seers of the Throne. The real mistake is placing the Father as a major Exarch.

See, the Unity represents fascism, straight up - the idea that a nation should place itself, entirely, into the service of a state and be organized toward a single goal. The Chancellor represents materialism, the idea that matter is the basic reality and minds a mere byproduct. And the Father represents fideism, the idea that reason is inherently corrupt and leads only to sin, and that only uncritical obedience to authority can instill virtue....
