I don't know enough of what's in your plans already to be able to reply effectively so I won't say any more. But for the people who managed to twist my words that wasn't exactly what I meant.
I guess I just find it strange hearing the words elf and human being used as lesser races that have no civilization whatsoever because they are slaves to another race. There is nothing wrong with the idea I suppose but I personally would find it too hard to get my head around to be able to enjoy properly.
Good luck though!
