The idea is indeed quite interesting; apologies if I was misunderstood.
Ah, lovely.
To comment on your statements more in-depth, as
@Didgeridont and
@Life in Stasis touched upon, while there is a clearly defined right and wrong, it's not a universal notion but rather based on the perceptions of two difference races and their divine inspiration. The four named demons—Belial, Azazel, Moloch, and Dagon—for example, are the four nobles that betrayed the First Sovereign, leading to his death and the fall of the empire. There might also be individual Ashkanai that don't condone the practices and behaviors of their race. I was thinking that the characters would meet such an Ashkanai in the story, just to put them through such a scenario and moral test.
The 'dark truth about the empire' would be that there are traitors, that there are humans who don't agree with the empire. When you are deeply brainwashed from the time of infancy, any derivation of your world perception becomes extremely disturbing even if it might be an obvious thing. People are individuals, all of them will not agree with a 'greater good'. But, those brainwashed by that greater good could never understand that. So, the 'dark truth' can also be the extent of the deep propaganda, the need for a common perception that ignores the individual. So, something that the characters can go through is doubt. "Why would there be traitors? What don't they agree with the empire? How could they not see the light? Is the empire wrong?"
