This is a question particularly with regards to Marines of all stripes: renegades, loyalists, chaos, etc.
Whenever you submitted a pitch to BL with regards to marines, were you working with established chapters or did you experiment with DIYs? Does BL prefer people to send in submissions that relate to established chapters, as in they have a name and some background or established chapters with just a name or new chapters that are the writer's own creation?
I've developed a lot of backstory for a chapter of my own and it is featuring in one of my submissions for the upcoming window. A concern raised when I asked for opinions on the sample was that it was risky to use a chapter of my own for it. Is that really the case? Would it be one of the negative points for the submission or does it depend on how the chapter is developed in the sample/short-story?
[Edit: I went through a lot of established chapters to get some idea on which ones might fit, and barring a few obvious and already well-used ones, I didn't really feel a connection with any of them and most of them happened to be either of unknown foundings or unknown primarchs or whatever and I just feel that that is a concept over-used in a lot of fanfic.]
Any and all thoughts are welcome.
