It shall be thusly relayed. I'm actually glad to hear that the guns should go on the outside, I had thought they would go in the middle of the ship, and it'd be all long and skinny, bullet shaped, y'know?
That's not much fun to look at. Bit too freudian for me, and what do you do when your freudian image looks like a damned cigar? That's like starting a race with a wrecked car.
I guess they aren't really the bad guys on purpose, they just ended up that way. They were the first human colony out of the Sol system, and they just found the worst planet they possibly could, covered in psychic fungus, and inhabited by big monsters that had this creepy obsession with the natural order, which apparently involved having your brain eaten by zee fungus.
Well, they killed them all, and planted grass, which apparently overpowered the hell out of the fungus, and reduced it all to this black ooze beneath the surface that they burn like oil. Problem is, the ooze is still psychic, and it reaches out to them.
Now they have a really strict, orwellian society with strong religious overtones. If you fuck up, ever, they send you out to "the black fields," where you either die, end up making contact with the ooze and becoming an "Angel Eater," which is one of those creepy psychic guys, or survive long enough to return from exile and get another chance at being useful to society.
And then, straight after this, they find out that that planet was Soldarin Imperial property, so now they're at war with people they've never met. It's good times.
