I have an old rebellious Infernal concept I'd dig. Almost all of the Solar-grade power, almost all of the sidereal weirdness, a slightly different flavour of anti hero than Abyssals, and what I felt was a legitimate concept for a character who had both a legitimate reason to throw off the yoke of the Yozi's brainwashing (this was assisted by the Throwback flaw and the True Love merit) and a way to upset the Reclamation without being Tormented forever.
When I first put the character together, he had stupid amounts of backstory, and the ST gave me extra bonus xp for that, but I could rebuild him as book-standard.
I guess there's a lot of Infernal hatred out there, and I don't exactly understand it, but if anyone is still interested in doing this, I'm in. The same character works as a Solar (but differently) or an Abyssal with slight changes to background. Sidereals too.
Really, I suppose it was just Lunars that never grabbed me and shook the interest into me.
