Astartes start as as normal human beings and are changed into astartes via chemical alteration, surgery, and psyhco-conditioning. As a baseline difference, Big E and the Primarchs were "Born that way". A lot of recruits actually die in this last stage of becoming an Astartes.īoth the Emperor and the Primarchs are wholly different from the Adeptus Astartes. You have to maintain your levels of excellence and on top of all of that you have to posses some luck as the implanting process doesn't take every time. So if you are unlucky to get selected by a Chapter for induction you have to be mentally and physicaly tough. So the Adeptus Astartes means literally those who conquer the stars aka Space Marines.īy my very literal translation anybody could be an Adeptus Astartes but nobody does it as good or as fast as the Emperors Space Marines.īut in the W40k it means that ordinary humans that survive decades of grueling mental and psycic testing and organ implants get to call themselves Adeptus Astartes. In some of the Horus Heresy books it is mentioned that the Primarchs have some other organs not in the "normal" Astartes.Īstartes means Stars, Adeptus means the ones that get hold of something. Its like comparing a copy of a copy of Mona Lisa picture with the original painted by a 10 year old. Astartes are made in the image of the Primarchs.

Primarchs are much more than the Astartes too. Emperor - He is not Astartes, Astartes is less than The Emperor as they are made by the Emperor twice removed.
