As the time draws near I feel we must make ourselves know, secrecy is of the greatest importance but in the coming months we must gather our forces to destroy the Imperuim of man! We shall achieve our goals and slaughter the fools who try to stop us!! I am Alpharuis, FOR THE EMPEROR!
There were actually triplets, but Betas didn't grow properly and now works as a farm animal on an agriworld. It's rumoured that all three still keep in touch, however. Alpharius and Omegon indulge their weakest brother by praising his work to further the spread of Chaos in the Imperium. He can commonly be seen standing aimlessly on busy roadways to block vehicles, laying well-hidden manure traps and very rarely confiding the secrets of the dark gods in his fellow farm animals. Indeed, the Inquisition has already had to slay several sheep, who were thought to be plotting to assassinate the God-Emperor after huddling together and baa'ing heretically, though Betas himself remains undetected and at large.
I know not what nonsense you speak about brothers but we shall kill you in the most gruesome way imaginable for this insult to our beloved primarch!
Calm yourself, marine. I spoke no insults, I was merely sharing some little-known lore about your enigmatic legion.
The ultramarines are cattle ranchers, with their prize cattle being marneus cow-gar... ...ok I am sorry for that one, that was awful, I'll just head back to ork forum.
No, I'M ALPHARIUS! (seriously though, i dont understand how a legion can perform tactically when they all think they're the primarch...)
