Ok so I was just wondering this: I know that space marine chapters send samples of Geneseed to the mechanicum/administratum as like a monitoring thing and tests for purity, but I was wondering what happens when they have enough surplus geneseed to make a new chapter? Such things can happen if a Chapter can send in enough geneseed.
I'm aware The Imperium has the ability to make new marines with this surplus geneseed, but how is the organization of a new chapter carried out? I mean I know recruits would become scouts and then marines and so on, but who monitors the first generation? Who are the leaders and commanders of a 1st generation of a space marine chapter? Is a chapter master designated from the Parent Chapter, maybe captains too, or are these marines somehow cultivated, trained, and commanded by a different governing power until they can organize and govern themselves? This interests me, and if any of you fluffy fans out there can help me out, it would be awesome to know !
