The Family

The Family is a tribe of nocturnal vampires that live in Meresti Metro station, east of the settlement of Arefu in Fallout 3.

Background
Vance intends to help outcasts that engage in cannibalism by reigning in their hunger for human flesh and convincing them to only drink blood. Their lifestyle emphasizes survival above all else as opposed to killing for sport or senseless murder. Before they join the Family, each prospective member is asked to seek solitude and meditate on whether or not they should stay with the Family or control their urges by themselves. The Family has a series of rules, which members must follow to remain a part of the group.

The humans of the wasteland insult the group and call for their "extermination or reform." He preaches to the Family that they are no different than any other wastelander that has killed in order to put food on their table or protect their territory, and that the Family would be insane to ignore the adaptation they have been provided by evolution.

The group repetitively raids Arefu, a small village west of their home. In their latest raid, they captured and brought inhabitant Ian West back to the train station. Ian is an individual who was overwhelmed by cannibalism, recently killing his parents. The leader of Arefu, Evan King, pleads with the Lone Wanderer to deal with the Family. The quest Blood Ties provides an opportunity for the Lone Wanderer to ensure the two groups can live peacefully.

Hacking into the Family's terminals will turn the Family hostile, even though the terminal itself is not marked as owned. This happens only if Vance or any other member of the Family did not give you the password.
