Yeah, become a god. Not evil, not good, just my own. Go wherever you like, see things you would never see otherwise, live forever, do stuff down on Faerun (and other worlds) and "up in the coulds". Yeah, that's neat.
As a mortal.. Heh, would only probably stay with Jaheira. She's a woman who knows what she wants, how, when, how to get it and is a strong person. Aerie is too whiny, Vicky too crikey - alignment change or not, a person will remain the one he/she always was. Nah, better be a god, all this "earthly meddling" is just too bothersome
