Carol (Fallout 3)

Carol is a ghoul hotel proprietor residing in the Underworld. She is Gob's "mother", although Ghouls don't give birth. He is like a son to her. You can rent a room for 120 caps, and listen to a long story about her life. She is more than 200 years old.

The history of her life is very dramatic, but it provides a good account about how the war was and how the survivors suffered the radiation effects and the chaos.

Trivia
Carol is evidently a lesbian as she sleeps in the same bed with Greta, whom she tells you she was lucky enough to find after coming to Underworld and whom she calls "Darling" and such other names. Carlo also mentions Greta used to feel a bit jealous of Gob, and when the character tells her about Gob's whereabouts, she begs to advice Gob about not leaving the place he is in, surely this has to do with Greta's Jealousy.
