So. I have Majin lore and the correlation to his blue rings that provide him the life that he needs to survive. Right. And I've mentioned that it's rather easy to kill a Mazin through taking two or more rings from them? Since their souls come from that power alone?
Ok so now picture that power going to the wrong person — someone who hates how life works, cycles, "fun" being "infinite" — and now you have it. The Wrong Person. Faker.
He gets ahold of the Mazin species, realizes how fun it is to kill them, eventually DOES plan to kill all of them ,,, and holds enough power to harness both forms of his (Faker and True Form). Wholeheartedly just doing this to get back at Lord X and hurt his loved ones
That's basically all I have for now :) The rings he steals from the mazins turn black. The longer he harnesses Mazin souls, the more "ghosts" appear in them.
I'm considering calling it something simple, like- The Black Rings AU? It conveys the message clearer LOL ,, More info coming soon since I do like to concept with the idea of Lord X having emotions, his plans being ambushed by his loved one being hurt yet alone with his species, a son that warps into his dad's perception of "evil" — and . Yeah :J letting that boy be evil as he wants to
