Editing Omegon (section)

===Alpharius vs Omegon===
Alpharius/Omegon sided with [[Horus]] despite being explicitly told by [[The Cabal]] prior to the Heresy that if Horus won it would mean the end of the human race but the ultimate victory against Chaos. While if the Emperor won it would mean humanity survives long enough to see the decay and eventual death of the galaxy. A Catch 22 with '''two''' undesirable outcomes, but hey, the Alpha Legion has two Primarchs, go figure?
*By the time of ''Vulkan Lives'', the Cabal have apparently written off their "Alpharius Gambit" as a failure, despite from all appearances that the Alpha Legion joined Horus just like they wanted.

Omegon discretely plotted against Alpharius to destroy an Alpha Legion facility which was causing warp storms and preventing the [[White Scars]] from returning to Terra. If this facility was not destroyed the White Scars would not have been present during the final battle.
*Evidence of one brother conspiring against the other? Just like the rest of the Horus Heresy. Just because they are twins it doesn't mean they are always of the same mindset.

In '''Vengeful Spirit''' by Graham McNeill, during a conversation between Malcador and the Emperor, Malcador reveals that the Dark Angels had come to the aid of Leman Russ and the Space Wolves against the Alpha Legion, to which the Emperor replies: ''"Alpharius...my son, what chance did you give my dream?"'' This line is actually very important on many levels. First it indicates that the Emperor is either unaware that Alpharius Omegon is actually two twin Primarchs, which seems unlikely given his whole creation of them using parts of his godlike power and psyche (all the more so given that when Word Bearers were shown a vision of the birthing vault "too many limbs" were visible in pod XX), '''or''' that he IS aware of their dual nature but knows that, while Alpharius could give up on the Emperor's dream, Omegon would never ''actually'' turn on him. If this latter part is the truth, it could indicate that Alpharius and Omegon haven't always been together.

In '''Seventh Serpent''' also by Graham McNeill, a sizable fleet of Alpha Legion Loyalists was preparing to join the war effort, until Traitor-Alpharius manipulates the Shattered Legion Loyalists into destroying them, under the ironic pretext of assassinating "Alpharius".
*Alpharius refers to himself here as ''"the one and only"'', which at a stretch might be a subtle hint that he has done away with his twin. As the existence of his twin is a monumental secret that there would be no need to draw attention to the fact there is only one of him, short of [[Primarch|ego]] that is.
*The Loyalist Alpha Legionnaires queried ''"which one of them is it?"'' upon realising that other Alpha Legionnaires were in orbit. Then later determined ''"You're one of <u>his</u>"'' as if the distinction between the two Primarchs mattered at this point.
