So who do the Blood Ravens descend from?

The Fallen

Yes, there are a few. 1d4chan has a list up of at least most of them, if not all.

space sharks were on the fence for a while, heavily learning towards Night Lords I think, but there was even some speculation of World Eaters. I think they're pretty clear cut Ravens now though.

Minotaurs were speculated to be World Eaters before their redesign.

Red Scorpions also have shades of Emperor's Children.

Blood Ravens are pretty clearly Thousand Sons though, based on that one prophetess or something seeing a vision about fatherless sons of Magnus, with a strong tie to the Blood Ravens.

I think one or more of the Grey Knights' progenitors were from the heretics side

I am not sure of confirmed but the Grey Knight may have been Sons of Horus that were still loyal to big E

Silver Skulls are almost 100% confirmed to be either predominantly Iron Warriors geneseed under Ultramarine mask, or Ultramarine descendants who wear Iron Warriors trappings, and both of them are because they were almost 100% confirmed to be founded by Warsmith Dantioch under RG's direct approval as an Ultramarine successor.

There is a loyalist chapter (whose name escapes me) where virtually all of their members are abnormally tough, dour, and resistant to chemical weapons, and their geneseed is under Inquisitorial seal. Strongly implied to be Death Guard descendants.

Red Scorpions are strongly implied to be descended from Emperors Children loyalists, and geneseed is similarly under lock and key.

My Dudes are Loyalist Word Bearers who Costanza'd their way into getting classed as a Second Founding chapter during the Scouring, and in the present time have virtually no memory of their origins save their cabal of Chaplains. They originally sold their services to the Ordo Hereticus and a specific lineage of powerful Inquisitors, who guaranteed their "safety" and that they'd keep the records secret if they come when called, which they still maintain to the present day (Though the marines no longer recall why they have an oath to the Inquisition, only that they do and always have) and they have a raging hateboner of all Word Bearers. Ironically, they are classed as being Ultramarines successors.

Retconned. Arvida is Janus and the lost fleet returned in "Crimson King".

Not the Thousand Sons. It's been openly stated by both Aaron Demski-Bowden and Laurie Golding, the Black Library loremaster, that the Blood Ravens aren't descended from the Thousand Sons and there are no Chapters founded with Traitor gene-seed.

They're probably just the remnants of all the original Librarius members thrown together into 1 chapter.

>There is a loyalist chapter (whose name escapes me) where virtually all of their members are abnormally tough, dour, and resistant to chemical weapons, and their geneseed is under Inquisitorial seal. Strongly implied to be Death Guard descendants.
Sons of Antaeus, but as per , it's just a coincidence.

The grey knights themselves are a splinter from a traitor group; The Knights-Errant

A handful of ones that are highly likely, but not outright confirmed, as far as that goes.

As far as I'm aware, the Word Bearers are the only ones that don't have any because they cleaned house early on before the Dropsite Massacre.

Janus lives at least for 1000 years beyond the Heresy and is still Grandmaster at the time of the Beheading.

Their first Chapter-Master was one, Garviel Loken. I recall a Thousand Son and I believe a World Eater being among the first of their number as well.

>World Eater

How the fuck does that work? Didn't those guys ALL have the nails? I'd assume that would make them automatically turn traitor given that you'd go bonkers.

>Are there any other loyalist splinters of Chaos marines?
Literally zero. At most we get a few cheeky hints that have been exaggerated by the headcanon of fa/tg/uys. Some are just baffling.

>Didn't those guys ALL have the nails?
Most did, but not all of them, especially among the Librarius.

Those who did not take the nails were ostracized by the rest of the Legion, and were among the first to be slaughtered at Istvaan III. Even among the Loyalists there were those who took the nails, but still remained in their hearts loyal to the Imperium, though virtually none of them survived on account of being suicidal manics who charged headfirst into enemy guns out of pure rage and heartbreak.

> there are no Chapters founded with Traitor gene-seed.

Well that's rather silly. It invalidates so many player made chapters.

That's because it's also not confirmed true. ADB and LG can say whatever they want, but there is multiple contradictory evidence against it from people who equal to them in the company.

It's basically an "open secret" until GW itself confirms one way or the other.

Also fuck ADB. He makes Chaos look bad.

LG is literally the LOREMASTER.

McNeil in Thousand Sons all but confirmed it, but Goulding and ADB don't like the idea so they started a purge. Goulding's apparently left BL though, so depending on how much influence ADB has and whoever the new editor is, that may change back towards 1k Sons Successors.
40k """""""""""""""""""""""canon""""""""""""""""""""" changes based on the whims of whoever wrote the last book and vaguely by whoever is editor at any given moment, so it's best not to put too much thought into it. Though I know autists literally can't help themselves.

>ADB and Golding
Who cares. Until a proper member of GW confirms or doesn't it's in the air
BL is such a collosal clusterfuck it's not a surpise they have loose lips and dropping sales

I'd like it if GW actually weighed in on the matter, considering that the BloodRavens have been gradually getting more exposure within their stores bit by bit.
First it was just flavour in white dwarf and the odd couple painted marines in the codex, then it was on the front of merchandise (admittedly desert grass tufts) and recently named characters in that deathwatch game box (and I suppose the model for Angelos if you count Forgeworld stuff as well).
If they Are gradually upping the exposure, it would be nice to have some official recognition.

Which was contradicted by Alan Bligh before he died. Golding is a twat, and ADB writes such heartfelt Chaos fanwank I thought he would jizz on himself at the thought of getting Traitor bloodlines redeemed.

Malcador's Knights Errant are NOT the GKs yet, and not all of them will be. Pretty sure most of them won't live that long.

>retcon to make things more lame

But why?

>implying anyone in authority at Gee Dubs is competent

That's why i had BL/GW more than even their price hikes
They misuse their IP and not get punished for it

If I remember my memery, the Bloody Magpies are descended from Primarch Aran.

Near as I can figure, the Carcharodons have a mixed geneseed pool after reading Red Tithe.

Okay, the late Alan Bligh left huge hints between IA10 and the Horus Heresy black book chapter on the Ravens (Volume 3), it is known that Corax kicked out Arkhas Fal, the former XIX Legion commander, and most of the Terrans. Using the Nicor as a flagship, they went out on permanent nomad status.

But they have some weirdnesses. Yeah, more feral XIX seed will look like VIII Legion seed, but in Book 6 we have Night Lords garrisons being looted, including of geneseed, by renegade XIX Legion troops of the Ashen Claws.

Also, there is a scene in Red Tithe where their ship uses Ursus Claws. This is a signature weapon of the XII Legion. So they probably jacked the ship so long ago they forgot where they got it, and if they stole geneseed from the VIII, they probably stole from the XII.

After all, their chief librarian comments about one of the Terminator sergeants something like "his anger made it easy to tell where his genes had come from".

In short, if the Carcharodons are salvaging armor parts off enemy dead, they are definitely taking progenoid glands.

The ancestry of the Blood Ravens is a hotly contested debate, the truth of which is a closely guarded secret the likes of which would probably start another civil war within the chapter. Best to leave the Unknown Primarch unknown.

>40k """""""""""""""""""""""canon""""""""""""""""""""" changes based on the whims of whoever wrote the last book and vaguely by whoever is editor at any given moment, so it's best not to put too much thought into it.
A better way to put it is that GW doesn't give a fuck about canon. But they recognize that pretending that it exists may increase sales.
