Not sure if someone already said this but if they added another race I would rather see Gensai, they are suppose to be the most common plane-touched race for Toril. I generally remember them from my 3rd edition forgotten realms book and they usually showed up in forgotten realms campaign guides after also. Along with being in Nwn2 not sure if they made it in NwN1 though.
