@The_written_John Well if their mother is a demon I would think that their mother is a first generation demon, her children would be second generation demons, and Lux's children would be third generation demons (unless their father was a 1st gen) which would make her children chaos scarred.
Although, of course, this is mostly a cosmetic discussion and doesn't really effect the character, I was just mentioning it.
(Edit: I haven't read your full history, so I wouldn't say it was pointless, if the chaos scarred part was important I'm sure there's some adjustment that could be done D: )
