User blog:Jabberwokk/Primarch's Roles

In Prospero Burns we are told that each Primarch was created with a specific goal in mind. Admittedly, I haven't read all the books yet, but I was wondering if we had a clear definition of each role the Emperor intended for the Primarchs, here are a list of those we know, and those I suspect, as well as the rest of the known primarchs to keep it orderly


 * Legion 1: Lion El'Jonson
 * Legion 2: Missing Primarch
 * Legion 3: Lucius the Eternal
 * Legion 4: Perturabo
 * Legion 5: Jaghatai Khan
