Which current chapter will fall to chaos first?

[DWest]

I would find this plot EXTREMELY interesting. I doubt GW will ever go with it, but wouldn't that be something? A band of Chaos marines seeking to throw off the chains of Chaos and find a place among the loyalists? That would be neat.

It's not a whole band, but in the Deathwatch RPG, the background of the specialist Black Shields (Marines who forsake their past and become wholly a member of the Deathwatch) strongly implies some Chaos Marines have chosen this path to return to the fold.

Also in the category of "we'll never get a black-n-white answer, but it brings up a neat possibility", with the implications in the HH novels that the Ultramarines absorbed the survivors of the 2nd and 11th Legions, I wonder what would happen if a group of Ultras discovered that not only were they not created from Guilliman's gene-seed, but that their gene-seed came from a Primarch who had done something so bad as to get his likeness scrubbed out where even Horus still stands?

I recall reading somewhere that marines who are adopted into other chapters are usually (ie. not when they are tithed as part of an effort to revive the receiving chapter, but when they are taken in as a charity) their geneseed is not harvested. So the II and XI Legions would have died out, even though their survivors were given refuge by the Ultramarines.

That said, it's still a neat idea. And there are reasons why that geneseed might have been preserved, like a special order from the Inquisition or the Magos Biologis.

I think it would be most likely for an inquisitor to have a pet chaos marine but still serve the golden throne. Also you are talking a massive lore shift here so the only chapters that could come back would be alpha legion and word bearers and maybe some night lords as they don't really like chaos to start with.

I know a new faction of renegade renegades hated by everyone and serving them selves to free them selves from the grip of chaos and be free once and for all

I say it’s the Space Wolves. Here is my theory. Canis Helix is surely some kind of mutation by chaos into Russ’s gene-seed during his infant. Once Abaddon can rampage enough to tear open the Eye of Terror, the power of the Warp will turn all of Space Wolves into Wulfens at least. Then the chapter will fall.

There's contradictory fluff regarding the SW, I'm pretty sure I've seen something saying that no space wolf has ever fallen to chaos, but then again I'm sure I've seen chaotic space wolves elsewhere in the Extended background universe, so who knows?

And then there's the single ill fated successor chapter...

[Denzark]

Bear in mind RENEGADE as opposed to Chaos Marines, have returned - Lamenters anybody? But with Chaos taint, it is hard to see a desire to return. If they had fully gone, ie mutations and daemonic possession, to have kicked the latter, would make them Illuminati - retro fluff winners. Whether or not the Imperium would let them return to the fold, I doubt. But a radical inquisitor could make use of a chapter or even a squad of redeemed marines.

In terms of turning, I think it more likely that successor chapters and later foundings turn - although having mutated geneseed is problematic. I think that for BA/SW, the most likely scenario would be their refusal to submit to Inquisitorial scrutiny making them outlaws, and then turning through a matter of necessity, this unlikely scenario would need a mad puritan to hold more sway with the High Lords of Terra who would pragmatically say 'They may be Space Vampire or Werewolves, but at least they're OUR Space Vampires and Werewolves.

[Wolfshade]

I imagine someone like the relictors you know they are half in anyway...

Space Wolves have fallen to Chaos in the past, there's a warband mentioned (Skyrar's Dark Wolves) in the previous Chaos Space Marine codex and Codex: Space Wolves says traitor members are lumped into the 13th company as symbolically lost.

[Mr.Pickelz]

Space Wolves, while having some fallen, would not fall as a chapter. While issues with the Canis Helix and their general tactics might make it seem to the rest of the imperium that they are traitors, or are on the road to it. The Space Wolves will forever be loyal to the Imperium/ Emperor. when the Strike Cruiser fell, it was because of the Blood Claws (their initiates) that overthrew the rest of the crew. Space wolves have a very built in, "it's better to die fighting" mentality. As for the 13th company, they are the company that is in the Eye of Terror fighting chaos, the reason the old Wolfen models and other figures from the pictures look a bit chaos'ish is that they're stuck in the eye with no reinforcements or suppiles, so they loot chaos gear to fix/ repair their stuff.

[Pater Sin]

I seem to remember reading somewhere that the Emperors children had the most stable geneseed of all the original legions, so it seems resonably feasable to me that some could be brought back into the Imperial fold. It also make sense that some ultramarines woud turn to chaos because they are all arrogant ****s who are totally convinced they are the the greates chapter of SM.
