Well, D&D alignment is (IMO) not a good way to decide who goes where when they die . . . despite it's semi-canon in D&D.It's weird that elves only go to Arvandor and might not stay with their friends or non-elven loved ones. But it's also odd that a NG husband and LG wife would be separated on death. Or be separated from a child for similar reasons
A more realistic conundrum would be a husband who's broken the precepts of his faith goes to "hell", while his wife and child get to go to "heaven". Even if that husband didn't really turn to evil, he just didn't follow the rules his god(s) set down for admission to heaven. This mirrors real-world religions in many cultures. Unfair, but realistically so . . . and possibly the basis of some good storytelling.
