Just out of interest (an possible character) I would like to know if you could have a two-headed character?

You are not restricted as to how your race looks, two heads are perfectly acceptable so long as you maintain that the extra head is just an anatomical appendage and not a power boost for you. (Which I am sure you know) Two heads are perfectly fine on a character but make sure you not trying to play as those three forbidden races, the Imperial Archangel, the Valar, and Maia.

nah, just a two-heade guy, with two personalities. Thought It might make an interesting charcter
