Renegades

That's what I'm saying – just change a few units for them. Besides, I think it's better to make them a clone of Haven than a race like the Sylvan. And there's no need to make good demons:) The division can be based on different criteria for different races – for example, you could create demons from the upper and lower circles of hell, or fire demons and ice demons; you could also create hellish demons and demons that live among people (I haven't come up with a name yet:)) – they would have different cultists and possessed individuals, but the last levels would be actual devils... In short, there are a hell of a lot of ways to divide the devils:D:D
