...emps saw no need to keep him (or her) around... Seems a waste of good Primarch material. A quick retrain and BAM! Another legion for the Great Crusade. Also, female Primarchs? Not really buying the idea for biology reasons. Not got the right chromosomes involved if the Primarchs were all clones of Emps.

As to something mentioned at the start of part 1 of this thread: It said "all records expunged during the Age of Apostasy." Perhaps one of the Lost Legions had something to do with a major very-bad-real-bad event in the AoA, so they expunged all data of said Legion, which had previously been kept as a historical record.
