There'll likely also be a great number of Astartes in any given Legion who were initially drawn from Terra, but for obvious reasons, that'd stop being a thing once the Primarchs are discovered and Legion bases established upon homeworlds.

Though actually, it sounds like you're already in contact with Yennefer on Skype, so that would simplify the matter substantially.
