Belle was the last ghoul to be successfully conceived and birthed on the Reservation.
Belle is unusually attractive for a ghoul. In fact, if it weren't for her lesions and symmetrically exposed bone, she would look like a pretty, though pale, human female. Even her hair is fairly full and long and thanks to the born ghoul’s ability to rapidly grow into adulthood within a month, she is also very curvy and fit looking. Since Belle is such an interesting success in the procreation experiment, Dr. Sebastian keeps a close eye on Belle and interacts with her very frequently. However, Belle does roam around the town on a daily basis, causing the other male ghouls to almost lose their jaws as she walks by.
Colonel Green's Quest: The Prisoner will have to kill Belle in order to clear Sub-Level 3. If the Prisoner has slept will Belle, she will not appear there. She will be hiding out in one of the shanty shacks awaiting the outcome of the battle.
Belle is very approachable and will freely interact with the Prisoner. If the Prisoner lacks a high Charisma (< 4), she will aggressively flirt with him opening up opportunities for a sexual encounter with her. Since Belle's quarters are on Sub-Level 3, and since Willem restricts all access to only those he visually approves, Belle will lead the Prisoner to one of the rooms on Sub-Level 1 (the occupants of the sleeping quarters freely give up their room for a born ghoul – it's like a god to them). A particularly worthy performance by the Prisoner (Endurance > 7) will get Belle to become completely enamored with him and garner more information about Sub-Level 3. A major side effect of such an encounter will be that Belle becomes pregnant. In the event of this, it was considered by developers that an ending slide for the Reservation would include a "ghoul junior."
