I have read lore and played games of the 40k setting for some years now, I admittedly don't know everything about 40k, and this is one of those moments. Does anyone know about Custodes recruitment? I read somewhere that most of them were descendants of the subjugated warlords of Terra, beaten by The Emperor of Mankind during the Unification Wars, I know that there are roughly 10,000 Custodes at any given time, but how do they replace there dead (I also know that any time they lose the battle never happened shut up you're a heretic), will they just grab any random person, or child, off the streets of Terra? I understand the augmentation process is a secret. Do they have Initiates in a similar manner that Astartes do (having a scout company etc.)? I know that they are trained in every way you could possible murder something, as well as "diplomatic"** skills, how long does it take to train them? Any help is appreciated thanks in advance.
**as in if I have to repeat myself I will blow your fracking head off.
P.S. Also on an unrelated side note, does anyone know what happened to the Cadian stuff on FW? I was looking to buy some Hazardous Environment bits but they are just completely gone.
