Garlean timeline question

[Bright-Flower]

I'm pretty sure the 'get back at them for mistreating us' thing is just propagnda. Maybe the general Garlean population believe it and the rank and file military, and what they espouse to their enemies. But I think it's just that, propaganda. The real reason Solus founded the empire wasn't revenge against the savages or to stop primals. The Empire was founded to turn Garlemald into an instrument to cause a calamity by the Ascians. But of course, they can't just tell the Garlean people about all of that. Only the people at the very top seem ti know the truth. Even Varis seemed ignorant of the truth until he actually took the throne.

Nobody wants to go to war to cause civilization collapsing disasters and carry out the will of mysterious robed fiends. But to get back at the savages and stop them from destroying the world with their reckless eikons? That's a lot easier to sell to your own people.
