It's hard to imagine a world full of only humans. You didn't even have any elves or dwarves? Or orcs? It must have made things more peaceful, if nothing else. Fewer differences to go to war over.
I never thought about people living in space before I got here, either. I assumed it was mostly empty. I guess everyone has their own sense of normal.
That's a good while. I have an idea! Could you tell me the best and the worst thing about it?
