Horus Heresy turncoats?
I really like the fact that there is a schism in the White Scars as well as whatever is going on with the Dark Angels.
What I would like to see however is this, traitors who having sided with Horus thinking ‘hang on a minute, all this murdering, mutilating, debauchery, wanton destruction, pacts with Chaos etc is not what we signed up for’ and then turn back to the Emperor’s side (or at least try to). I thought this was a hinted outcome for Horus Aximand. I’m not sure if Aximand will go this way as he seems too far gone.
Would anybody else like to see this or think it will happen in a future Black Library novel? I even think it could work in the 40k setting.
