I personally believe that 90% of Alpha Legion warbands have actually fallen to Chaos. However, whatever happened to the Primarchs themselves is a mystery, so I also like to think they are still loyal but working behind the scenes with their own little warband.

Btw, in the short story, Omegon wasn't actually plotting something. It sounded more like he was hiding something from Alpharius, but it was really unclear simply because he went to his room privately to look at two suits of Power Armour, one standard and one 'special' in some way.
