Editing Blood Ravens (section)

===Founded by Janus?===
If the Blood Ravens were somehow founded by Arvida, after his transformation into Janus, then it would well explain how the Blood Ravens suffer neither the Flesh Change, nor Rubric. As Janus was created by infusing Arvida with a shard of Magnus' soul. Magnus was noted to have a stabilising effect on the Thousand Sons' gene-seed (basically stabilising the warp-fuckery that is inherent to the Tsons gene-seed). Arvida merging directly with a shard of Magnus could have easily perma-fixed not only his body but his gene-seed as well, so even gene-seed grown from his progenoid glands would not suffer the gene-flaws. However, after the merge, "Janus" claimed that he had no memory of his life as Arvida. He could have later remembered his past life, or as the Grand Master of the Grey Knights, there would be nothing stopping him from finding out. And being a shard of Magnus (and one of the Thousand Sons), finding lost knowledge would always be of interest to him. Alternatively, he may have been under orders from [[Malcador]] or the Emperor to claim as such.

The hints at Janus being the founder of the Blood Ravens is the strongest of any potential individual:
* A statement he made, without anyone around to hear him, "'Knowledge is Power'", is the first part of the Blood Raven's chapter motto.
* He was a member of the Thousand Sons' Corvidae Cult, which the Blood Ravens are as close to confirmed to be descended from as you can hope for.	
* Being the Grand Master of the Grey Knights, wiping any record of his own existence would easily explain the Blood Ravens' inability in discovering their real founder.
* Related to the above, what records of the Blood Ravens exist are redacted under the order of the Ordo Maellus, which the Grey Knights are a part of.	
* The Blood Ravens have worked alongside the Grey Knights before, and apparently have a good relationship with them as the Blood Ravens took a suit of Grey Knight armour and the GK's didn't do anything about it and in dawn of war dark crusade and soul storm the marines (the faction it self pattered after the Blood Ravens), could use a unit of Grey Knights.
* The oldest known leader of the Blood Ravens is an Astartes named Azariah Vidya, who was noted to already have extensive knowledge/experience in combating the forces of Chaos and used it to OP effect against the Alpha Legion, "Azariah Vidya" sounding similar name to "Arvida". Wouldn't be like he hasn't changed his name before, from "Ianus" to "Janus".
* Janus disappeared sometime between 546.M32 and 290.M34, as by the latter date, the Grey Knights have a new Supreme Grandmaster.
