After having learned about Lorgar, I repeat the part of my theory that they 'landed' on a planet that had been completely corrupted by chaos. At the time of finding the Primarchs none of the others had been found on planets where Chaos had control over everything.

Another thought I had is what if the missing Primarchs had attempted to break from the Imperium and create their own empire, and had to be put down by the Wolves?
