Maybe one sided with Eldred or similar (The Cabal etc) after a warning like the that which was given to the Emperors Children and/or the Alpha Legion.

A prehemptive strike against the real first traitors (one legion) by the other (the reminding legion). I haven't read the books in a while to gather exact details but I know Eldred could reach out and communicate, he had willing and I seem to recall a suggestion that one legion was suggested as corrupted and another misguided. Paraphasing. I know the Cabal likewise had the motive and means. I know the Cabal had contact with Humanity, possibly/probably the Emperor so they may have spoken to other Primachs, they certainly talked about other human agents been unrealiable suggesting the two we know of are not the only ones. I'd guess a loyal primarch failing to do the job against a choas one would make humans alittle unrealiable in their eyes.

Potentially in an attempt to cut the cancer they did it in a manner which discredited the Imperium such as been the first to kill brother marines or disobey the Emperor. The Space Wolves may well then have been sent to finish the job.

Without reading the lot again and GWS making more information to go off, we'll never know but I could imagine it. Personally I think GWS are making a foolish decision to not tell the fans as people can make up chapters left, right and centre(second foundings etc) so I don't think that mystry chapters etc are a great tool, compared to a nice series of books or such.
