Since every one in the dungeon is vampirehead. Would the child end up like the little vampire that was in interview with a vampire.

Were she is bitten at the young age of 7 and has to stay that way.

Probly not a good Idea. I dont want the dungeon to be a den of pediphiles.
Maybe you go through a prolonged pregnancy and then you give birth. Then you come across the wizard or the alian and zot she is 18 and ready to be inslaved. Of course the mother would be incharge of the daughter and help in her training. (Sorry I like lesbian incest ) Some may not. As long as it is over the age of consent I do not see a problem with it. Not like the daughter is going to get pregged like if it was father daughter.

Lets not get into a discussion on the pros and cons of incest as I would surly lose.

Just remember this is a vertual dungeon. It is not real people.
