I totally stole this idea from Aegis Shield.
I have a bunch of ideas I really want written, but probably won't ever write myself, sooooo I'll just open my spacious cavern of a noggin and let loose my hellspawn upon you guys, yes? I don't care what you do with the ideas, I don't think I know what I wanted done with them anyway, I just thought 'Hey, this is cool premises!' wrote the idea down, and never really expanded on it so do whatever you like.
