But I don't think anything was said about him being a member of the Black Council.. Again lots of talk about, but no substance as to whether or not it really exists.. Oh I think there is some kind of connection, or at least perhaps some of the factions have was looks like the same aims but that doesn't mean they are part of a group called the Black Council.
I believe you're confusing Black Council with Black Court. Black Court's a vampire court, Black Council is Harry's name for the alliance of individuals from several nations working to undermine everything. The post you quote was about Black Court, not Black Council.
The Jade Court are classic Chinese hopping vampires, breath or chi stealers meaning the Jampires have more in common with the Whampires (aside from both being fans of British rock bands).
Reds and Blacks both require blood and the life force suspended in that to feed, rather than take the life force direct.
My theory is Drakul is wearing a Starborn body, Kemmler was after something similar but was too early for Harry’s generation, Justin in this theory was waiting for Kemmler to return, Harry was to be the new body for Kemmler, and with a Starborn body Kemmler had the last piece of the jigsaw for a successful Darkhallow (which is why it nearly killed Cowl), it explains why Kemmler never did the Darkhallow when he could have used the power to crush the White Council, the only Starborn body around from previous generations was already occupied by Drakul, and I doubt even Kemmler fancied taking him on.
It may be that there is a physical limitation on a mortal absorbing too much power unless it is through a construct like a Mantle, or mother Winters Walking Stick, or they are a Starborn.
Agree on Drakul being in a Starborn body- I'd propose that the body unexpectedly put a bounds on his ability to manifest, like it was itself a miniature living Outer Gate, and that's why he's stuck.
Agree that Harry was intended as a Kemmler vessel, or a vessel for Justin doing a Corpsetaker. Talent needs to be developed to not wither, so Harry needed training regardless.
Disagree on Kemmler not having done a Darkhallow. I rather think he must have done at least a preliminary test-of-concept version, but it was limited for some reason- perhaps because he wasn't starborn. May have limited him to a certain "volume" of ghost consumption- the prize, I think, is to do one at Demonreach, which he would well understand.
Also disagree on available Starborn. I think Rashid is one. Mab and Titania might be. Hell, maybe that's part of the White King's secret and why he'll do deals with Outsiders. But Harry, with a powerful wizard talent and affinity for the more destructive aspects of it, is a prize of a starborn host.
I'm in agreement with Mira about Harry's father mattering, even if it's in a literary sense- in a "in the end what matters is that Harry is more Malcolm's son than Margaret's" story-sense. Everything sees his mother in everything he does- her power, her secrets, her talents, even her height- but what's inside isn't corrupt in the same way. Harry isn't a saint, but even the Temptress among the Fallen couldn't corrupt him. He's. . .excessively centered in himself. He's capable of doing evil he agrees to, and only when he agrees to it.
That's what I see, anyway, and I find it an interesting character to be the hero of the story. He's not necessarily nice, but he's . .independent. It's
his choices. He's centered in that. Doesn't accept coercion.
