Well, I'd prefer not to do your typical magical or mystical beings. Like elves and orcs? No. Too overdone. Perhaps we make our own races? Personally, I came up with the idea through a dream. I had been up until like 2:30 playing guild wars and the overexposure showed up in my sleep. I dreamt that I was my Asura engineer and all of this happened and that the people I was with were also Asura. We were fighting against the humans. But that was just my dream.
