legion - 5th edition grey knight codex is where the info is regarding their gene-seed but it's written by - brace yourself! - matthew ward.

i thought the primarchs were created before astartes. primarch genome was created and then each legion was created using the blueprints from the primarchs, no? have i missed something?
