But thats a lotta micro management and astarte are ultra rare so lets assume geneseed is integrated with the main line humans in this world. GeneSeed in 40k is extracted for existing Astarte that have had a progenoid organ for at least a few years, typically on death then crafted into the the 19 organs to be implanted in a male child under the age of 14. Once an astarte has the first nine organs in they are battle ready for Legionaries Astartes scout corps, with all 19 your pawn can become be a primarch worthy of challenging even Horus or the lords of chaos. Take it to become a Astarte, complete with all bonus organs for optimal crusading. Slaughter and Butcher Human like to get GeneSeed. Mutates your pawns genetic code to be better down to every last cell. The cure for rejection of the additional 19 organ implants on the path to becoming a super human.
