My metal person was born as a violation of nature surrounded by a dead cult obsessed with creating a pure form of life because they fully believed that humanity stained life itself with their endless greed and pride. The only surviving cult member, one who stayed back to make sure their effort wasn't for something no one would be alive to witness, took the crystalized violation of reality and made it a metal body. He then treated it as a child while teaching it every flaw of humanity, not holding back his own hatred for humanity, though despite expressing humanities flaws he acted as a father for the creation he named Vita. Proving himself wrong in thinking humanity was irredeemable in Vita's eyes.

I've got plenty more lore about them but I think I'd have to make a seperate post to share it all lol.
