Indeed they will be. I'm going to try coming up with a CS first. Also, my demon race would be humanoid, just that some will be shorter than the average human being while others bigger. The imp variation will likely be the size of a young teenager while the pit lords will likely only be twice as tall, slightly shorter if that is too much.

EDIT: Lol had a funny thought. I wonder what will happen if your demon, my demon and a human being walks into the same room?
