The alpha legion are the Cold War personified.  They are really easy to understand once you know they are always playing both sides. They are both for and against the imperium equally.
Another thing id like to add , Dorn killed Omegon not Alpharius. Guillimon killed a regular Legionnaire disguised as Omegon , that’s why there was no big “ quickening from the Highlander bright light” like when all primarchs die.
Like all the primaches gamesworkshop do not know what to do with them, and can only cash in on bringing them back once. I think I’ve for monetary reasons they haven’t brought back more primarchs sooner. They are makinh tons of money now and no reason to gift the community with another Primarch return.  Just my thoughts , what ive gathered from the content available.
I enjoy your content good sir.
