Put me down as one of those 'from anywhere and anything' types...
I'm quite a 'current' individual, so if a piece of media I'm enjoying/consuming at a particular point in time generates an idea, I may or may not run with it, recalling stuff from elsewhere.
First and foremost, though, is the world of the aforementioned Prince Alecksiiz... think X-Men, Star Wars smushed together... that was how it started twenty years ago, and it's become simultaneously dystopic/idealistic/cynical (don't ask), become markedly different in tone and philosophy from those two franchises, and incorporated timelines going forwards of 500 years (so far... still need to find the best point at which to introduce the aliens...(!)) and backwards of 600 years with technological and biological evolution, but all started by a childhood of Saturday mornings watching the 90's X-Men cartoon.
Anyway, most of what I write are standalone stories set within this continuity (the core main story centred around Alecksiiz is a septet, but eh... less about that for now), and inspiration mostly comes from history, as it goes, and it mirrors the real world, none too subtly (albeit with two divergences). But bits and pieces from virtually everything I read/watch (be it anime, manga, novels, graphic novels, TV series or movies) will find some way into what I write...
