Editing Thousand Sons (section)

==Connections with the [[Blood Ravens]]?==
It's never proven to be absolutely [[canon]], but in the "A Thousand Sons" novel from the Horus Heresy book series, there are some hints that the Blood Ravens stemmed from a Thousand Sons cult who remained loyal to the Emperor, which was a large force of Thousand Sons marines who were sent outside Prospero before the Space Wolves came to fuck the whole planet over. Specifically, the most painfully obvious of the hints is this particular line from the novel where a [[remembrancer]] is using divination:

<center>'''''It's too late... the [[Space Wolves|Wolf]] is at the door and it hungers for blood. Oh, Throne... no, the blood! The Ravens, I see them too. The lost sons and a Raven of blood. They cry out for salvation and knowledge, but it is denied!'''''</center>

Since these Marines never fought the Space Wolves and weren't drawn into Magnus' plans of heresy and revenge, or didn't even hear about it, after getting their planet bombed, they remained loyal to the Emprah. Probably because they, like Leman Russ, discovered after the fact that it was a trick. Sucks to be Russ when he found out.

In the ''Age of Darkness'' short story ''Rebirth'', Revuel Arvida is the last survivor of a scouting party from a ship that made it back to Prospero. The end of the story has him saying "knowledge is power" and focusing on the raven of the Corvidae cult on his pauldron (also, the rest of his armour is red). He gets off of Prospero with the help of the White Scars later, after surviving for ages alone without food or water whilst fighting psychneuin, then getting involved in a fight against Mortarion's bodyguards (need we add that this was a fight between the Terminator elites of two Legions, and Arvida survived despite being clad in regular power armour), and finally creating a psychic beacon to get his and the Scars' arses off the planet. Except that wasn't final, as he spent four years at war beside the Scars, fighting the flesh-change, bitch-slapping Eidolon with his psychic powers and guiding the entire Legion fleet to Terra through the Webway. Compare his name to "Azariah Vidya," the earliest recorded (though not the first) Chapter Master of the Blood Ravens.

Eventually though it was revealed that Arvida merged with his Tutelary spirit and/or a broken Shard of Magnus which he left behind on Terra when he broke the Golden Throne. The resulting amalgamation cured Arvida's body of mutations (but sealed around one of his eyes with scar tissue) and took the name "Ianius" ''(also the name of his Tutelary)'', later to be known as Janus, the founder and the first Supreme Grand Master of the [[Grey Knights]], especially since physical descriptions of Janus show him with a squint in one of his eyes. Much shit was flipped by TS, BR, and GK fans that day, while fans of Arvida were just glad to know that his tale wouldn't end as a That Which Must Not Be Named...On the other hand, it does not explain what happened to his gene-seed (assuming it was replaced by implants from the Emperor like Epimethius having his Dark Angel gene-seed replaced and sealed).

And note that the Blood Ravens have no idea which legion or chapter they originally came from and the fact that they produce an unusually higher number of Psykers than your average marine chapter and the Thousand Sons were known to have a large number of Psykers in their legion, as well as having a fetish for various flavours of knowledge. Also, the Thousand Sons' pre-heresy colours are strikingly similar to the Blood Ravens', the only difference is that instead of a white trim, the Blood Ravens use black, but the armour's overall colour and their helmet's visor colour are virtually the same.

Additionally, certain records were found upon Kronus that alluded to the Chapter's origin, yet Thule had them destroyed. Some suggest that the evidence was so damning as to link them to prove this theory. Alternatively, it may simply be that the records were in fact [[Azariah Kyras]]' perverted [[/d/]]eviant porn stash and Thule destroyed it because of the sheer amount of extra-heresy it contains that it would drive any lesser man to insanity.

There is some more evidence that the Blood Ravens are a Thousand Sons offshoot in the book ''[[Dawn of War]]: Tempest'', but '''that''' was written by [[C.S. Goto]], so take it with a grain of salt.

The November 2016 issue of White Dwarf, and later the July 2019 issue, almost explicitly state that Blood Ravens are an offshoot of the Thousand Sons, although the reason why they show no symptoms of the Flesh Change is not explained.

In 2023 with the release of the newest Horus Heresy black book, the Siege of [[Cthonia]], we have a confirmed loyalist off shoot detachment of Thousand Sons, led by Magister Sul Kontep, who went to Terra to be arrested after the events of Prospero. They got sent to Cthonia accompanied by some [[Sisters of Silence]] as watchdogs. Fortunately, they got to kick plenty of ass and were able to escape the planet alongside [[Imperial Fists]] Castellan Evander Garrius. It's also said that they've survived as far as the Scouring.
