Having the white energy within him and the fact that he called upon a god to strengthen him when he was fighting Quinn I’d say Laxmus fits the bill not just as a celestial but also who gets his energy from taking lives like Ray said. Also most likely the one who’s behind the Red Vampire group that’s force turning humans or outright killing them.
I don't think Owen is around. I don't think getting a familiar could extend a life a thousand years or more, and I don't think it could grant immortality. I am however expecting something interesting to happen. One thought, while particularly evil and horrible is that Owen late in life, was blooded at his deathbed and somehow like having a meeting with Truedream or something similar got to move his lightning ability past the vampire curse that prevented vampires from learning elemental abilities. Richards royal knight ( I forgot what his name was) and buttler to Hilston got a copy of the blades copy ability through this method. there had to be other methods. I can imagine the equivalent exchange ability could probably also do something similar. while we left Vincent he didn't have his ability I can absolutely see him training some surviving tenth family members to the ability to plant some seeds for the future. We all know Peter is going to be Quinn's first follower. It's just who he is. On a side note I'm kinda dying to find out what happened to Alex the blood fairy forger.
So I just like how when reading this chapter and seeing all blood abilities were unlocked and could be used endlessly I instantly thought of quinn just shooting blood cannons non stop and then to later read those exact thoughts come up was very validating like really no normal behind human vampire or dhaphir would be able to touch him not to mention any injury they sustain makes him stronger and idk why quinn is worried about finding followers if he literally revealed himself as the hero quinn all he would have to do is ask people who believe in him to donate blood to the statues that apparently all traveler stations seem to have and with him going to the leader of the graylash maybe he can convince him to get his whole family to start
Also big question does bliss have any dedicated followers and if not I wonder why she doesn’t share her power like the death god but if her power is the opposite of death I would guess it would be based actually on birth so the number of human lives born into the world is her condition therefore eliminating the dalki and weakening the vampires was crucial for her and now she should be way more powerful than before due to the exponential growth of humanity and I say human lives because the vampires were created to kill humans and add power to the death god and I’m guessing bliss may have similarity created the werewolves but long before to protect humanity from the beasts or long lost Van who could control that special beast crystal from MDS I suspect he is the god of the beasts but became mostly forgotten after a war with bliss and the werewolves thus when reborn lost his memories see I think that’s where it started like she made the werewolves for that and then later the dragons appeared and led to the shadow which gave an opportunity to death to make the vampires which then led to the dalki which led to now
