An idea i came up with on the topic of the mssing primarchs is that the two had an arguement of some kind and it ended with the two fighting each other on a massive scale.

We know primarchs had fights between themselves, but what i'm talking about is a battle involving both sides entire legions, plus any imperial army units attatched to them. One of the Legions come out on top and annihlate the other. However, the Emperor finds out and sends the Space Wolves to kill his wayward son and bring an end to the madness. Leman goes and finishes off the Prmarch and his captains. Any survivors are sent to the Ultramarines legion and the embaressment is wiped from imerial records

Another possiblity is that both brothers fell to chaos before Horus and others did and tried a proto-horus heresy. They could of been a test done by the chaos gods to see how primarchs would react to becoming servants to chaos. Once again Leman Russ and the Space Wolves are sent in and kill the primarchs and any loyalist survivors are sent to the Ultramarines. The embaressment is wiped from imperial records
