One of my players wants to make an untouchable marine(with the game not even out yet!). I've never seen any in lore for such a thing and while I can say the chapter librarians would be none too pleased with something that could very well be tainted, the black templars present a small problem, what with the whole no librarian things and all. Anyone know any good reasons for or against such an idea? I just hate the whole "special snowflake" idea of a untouchable marine. My idea is that the untouchable gene doesn't go well with the organ implantation process, etc.
Any thoughts?
