Yes, that Cain, first born among humans, slayer of Abel, and so on. Most people don’t realize that when God placed the mark on him, saying he would punish anyone who harmed him sevenfold, he was including the angels. As a result, even Azrael won’t touch him, so Cain has lived on. In the old days we crossed paths frequently, but he was often very different. He went through phases. One century he’d be vowing revenge on God, the next he’d be trying to pay penance. There are a lot of Djinn like that, to be fair, but Cain wasn’t like us. He didn’t have anyone like him to cling to, any higher cause. He just kept living, no one willing to harm him.
In the modern age he’s become… peculiar. He had amassed considerable wealth, only to give his various companies away, embezzle an enormous quantity of wealth, and found several cults with a wide variety of beliefs. I’ve spoken to him a few times, even had his assistance on occasion.
In the past sometimes he would be living life like any other man, other times he would be intently focused on a single task, either his salvation or his grievances with God. Now… he strikes me as focused again… but I have no idea on what. He’s working to an end, but it could be anything.
What makes it more disturbing is that he’s gathering other immortal humans around him.
