Is GW hinting at a new Primarch with the Blood Ravens?

[Swordsman]

Magnus knows more about sorcery than Ahriman knows... is that so impossible? Ahriman may be the Chief Librarian/First Captain of the legion but Magnus is a Primarch, a psyker whose entire life has been spent in psykery/sorcery.

Ahriman was uncomfortable with the ritual being performed. Sorcery unnerved him is my point.

Regardless of his mastery level, it seems a bit odd to be so unfamiliar with sorcery as a sorcerer..

I'm fairly sure that all Thousand Sons were initiated into one of Prospero's cults, and that all had Tutelaries. Correct me if I'm wrong though.

Were the cult houses sorcerous cabals - and not just houses of psychic specialization?

[Skits]

The impression I got was that only the higher ranked/more powerful psykers forged a connection with a tutelary.

So, not all Sons were psykers, but all Sons who WERE psykers belonged to one of the five cults. However, not all psykers had Tutelaries.

I think thats something that started in BL books from the early 2000s onwards(the first word bearers novel for example, has basic pdf troopers having full knowledge of the traitor legions) and has leaked sideways into the design studio. Its a bit of a disconnect from the old fluff for me, but it seems to have kept to the BL section for the most part. I think the toning down of the punishments for encountering chaos more to do with the universe becoming a bit more black and white. Can't have the good guys doing things bad guys do. That makes them morally questionable .

I would strongly argue that it's less due to a desire to make the Imperium more heroic, and more to do with the fact its bloomin' hard to write a series of books about a set group of characters if they have their minds wiped every time they face Chaos and/or are executed. Gaunt's Ghosts for example would have ended after the first short story as the Imperium purged the remnants of a Regiment that was tainted by a Chaos attack during its founding. Uriel Ventris would have been left a mindblank automaton requiring retraining at the end of the fourth Ultramarines novel. Even the great Imperial Hero Ciaphas Cain would have likely spent most of his life toiling away in a concentration camp after the things he's witnessed.

Exactly. That often gets lost in translation. And I'd say that Uriel and his battle-brothers would have been wiped after the short story Chains of Command in which they fight the Night Lords. But yeah.

NO. The two Legions extirpated pre-Heresy are dead, gone and no-one talks of it. It's alluded to a whole lot in the HH books but with the common thread that even amongst the Primarchs, the two that had been expunged are not even talked of.

The original intent was for hobbyists to create their own chapters, but as the hobby expanded this was covered by the notion of more foundings, succesor chapters etc. Basically, create your own chapter if you want, but you don't get a Primarch - unless you tie your successor to a specific 'original' Legion. There are no 'new' Primarchs.
