For the Devils,
@Goldfish, when diving into accounts of their deeds, more context is necessary. For example, Viserys has been waging war against the Brazen Throne alongside his Shaitan and Djinn allies for the past couple years now. We could mention how the Erinyes faced the Brazen Throne's forces in battle and freed hundreds of people from slavery and torturous execution for failure to guard a convoy of Adamantine.
This does two things: Shows that
Devils broke their own chains, and then broke the chains of others in return. And secondly, they were useful for seizing two million tons of Bullion equivalent, which neatly explains "how did Viserys bankroll a military buildup on this scale in so short a time?"
The answer being raw power, obviously, but people fill in the blanks on their own all the time.
We could also mention other fig leafs like their participation in the Sarnori campaign against the hordes of undead, their skirmishing with agents of Mammon over the past couple of years in Westeros...
We can have the Inquisition encourage people in the right places to spread stories along the lines of "taming a shadowcat to ward off the wolves", or other takes. The important part is to counter populists who are running on a platform for "getting Devils out of Government". And maybe ensure they're publicly disgraced. In fact you should explicitly add <---to your vote as a thing we'll be focusing on.
