My guess is they got chastised and broken for breaking rules and edicts or going rogue I don't know but it'd be cool if ever a 40k end times comes the two legions come back from the void with furious intent except their respective primarchs are dead. It could be one was driven insane and the other maybe ditched the imperial creed about religion and went against the emperor leading open rebellion with his legion. Actually what if one of the primarchs landed on a forge world or a entirely xenos populated planet and thus learned whatever from them.
