Honestly, I don't even know how Bhaalspawn will factor into this game. It is a sequel with a new story, but likely the Bhaalspawn has to have some impact or influence on the events that led up to this game. Also all the answers right now are very vague so there is nothing really breaking? I mean, I decided to name my character off of one I play in a 4e campaign and rationalize it as him being bored and being in faerun and then getting picked up by the ship and getting nerfed to hell cause parasite + faerun.
