Editing MidHammer 40,000 (section)

==The Codex Astartes and the Controversy It Causes==
Because there were more loyalist [[Primarchs]] that could oppose [[Roboute Guilliman]] and the Emperor is apparently still a bit more present, coherent and vocal, the [[Codex Astartes]] isn't [[spiritual liege|as universally adopted as in the original 40k.]] Currently in the Imperium, Codex [[Astartes]] and Legio Astartes coexist, with the Legions more suited for planetary scale operations, and for sector-wide offense and defense (basically everything).

===Remaining Legions===
Loyalist marines are "split" into two different ideologies, depending on which idea their particular Primarchs supported and if their Legions even came through the Horus Heresy with enough Astartes remaining to still consider as real "Legions".

In practical terms [[troll|and with a bit of creative liberty,]] it would likely look like this for the remaining loyal "Legions" (though this is an estimate):

;Legion 1 "[[Dark Angels]]"
- Probably would remain as a Legion. Since they weren't exactly too thrilled anyway about [[A Game of Pretend|having to pretend to not be one]] after the Codex Astartes was adopted in the original timeline.

;Legion 3 "[[Emperor's Children]]"
- Had 110,000 Astartes at end of the [[Great Crusade]], and would not purge almost half of them like in the original timeline. No doubt also that Fulgrim, though he may not become dominated by Slaanesh, would still be too prideful and self-assured to put up with Guilliman's [[bullshit]] in this matter.

;Legion 5 "[[White Scars]]"
- 95,000 Astartes at the end of the Great Crusade. [[Jaghatai Khan]] should want to keep his men.

;Legion 6 "[[Space Wolves]]
- They hardly even bothered to respect the limitations of the Codex Astartes in the main timeline. No doubt they wouldn't bother at all here.

;Legion 12 "[[Imperial Fists]]"
- It's not yet clear what exactly happens with [[Rogal Dorn]] and his Legion in this [[alternative timeline]], but if he survives and with the other loyalist Primarchs around, maybe he'll retain his regular Legions. Especially since [[A Game of Pretend|this is another Legion that only sort of pretended to not be a Legion after "adopting" the Codex Astartes in mainline, like the Dark Angels.]]

;Legion 13 "[[Ultramarines]]"
- Ironically, Roboute Guilliman would probably want the Ultramarines to remain as a Legion, simply to counter his brothers who also have remaining effective Legions. [[troll|His whole Codex Astartes chapter limitations concept was really designed to limit his brothers from going like Horus again, after all;]] [[Imperium Secundus|not so much for limiting]] [[Matt Ward|himself.]] The Ultramarines allegedly had 250,000 Astartes at the start of the Horus Heresy... Anything above 1,000 Marines is considered too much for a mere Chapter, according to the Codex Astartes... No doubt Guilliman would have even more Marines surviving the Horus Heresy than in the original timeline as well, thanks to the weakened Horus Heresy. So even more motivation to keep the Legion for himself.

;Legion 15 "[[Thousand Sons]]"
- Allegedly had at least 80,000 Astartes before the [[Prospero|Fall of Prospero]] in the main timeline. No reason why [[Magnus the Red]] would want to give that up to the dweeb Guilliman.

;Legion 18 "[[Salamanders]]"
- Assuming a less massacry [[Drop Site Massacre]], the Salamanders would still have more than enough remaining Astartes for [[Vulkan]] to not want to give up his Legion's "real Legion" status.

;Legion 19 "[[Raven Guard]]"
- [[Corvus Corax]]' Legion [[derp|may have get screw harder than]] the Salamanders at the Drop Site Massacre, but they still have enough to remain a Legion.

===Legions Reformed into Codex Astartes-compliant "Chapters"===
;Blood Angels Chapter 
(Formerly Legion 9)<br>
- The Blood Angels get "chapter'd", just because [[Sanguinius]] is dead, and that Guilliman was known for being unnaturally persuasive as a writer and as a Primarch. Doubt any Primarch-less loyalist "Legions" would be able to remain as such in the face of [[spiritual liege|Guilliman's]] [[troll|efforts.]]

;Iron Hands Chapter
(Formerly Legion 10)<br>
- They get screwed so hard in the [[Drop Site Massacre]] and afterward, even more so than the Raven Guard and Salamanders, that even if it's a little bit less bad in this timeline, they'd probably have little more than enough for one functional chapter anyway. So, Ferrus Manus may presumably be coaxed by Guilliman into giving up his Legion status and allowing for a mere "Chapter". Since it's screwed anyway; why bother maintaining the pretense of having a one Chapter-sized "Legion"?

Overall, it looks like the Codex Astartes might be a bit of a flop in this [[alternate universe]], with only two Legions having good reasons to become demoted to chapters. [[troll|Bit of a shame for Guilliman, really.]]

Big question: [[Legion of the Damned]], does it become the Legion of Martyrs?
