Mother Curie III

Mother Curie III is the leader of a small cult which lives in the Holy Light Monastery in Springvale. A former Child of Atom, she preaches of the glory of the atom and recommends people to irradiate themselves as much as possible.

Mother Curie III is an extremely peaceful character, and does not become hostile if you killed Brother Gerard in order to enter the Monestery, or even if you flat out tell her that you're going to wipe out her cult. If threatened, she simply states that she expected some form of religious persecution and that she refuses to respond to violence with violence. If you initiate combat against the Holy Light cult, Curie will simply cower and flee. Her Feral Ghoul Reaver and Glowing One followers, however, are not so forgiving.

Trivia

 * Mother Curie III's name is an obvious reference to the famous Polish scientist "Madame" Marie Curie who is known as the "Mother of Radioactivity." Marie Curie's death was also caused by radiation poisoning, echoing what Mother Curie's cult is causing.
 * The Apostles of the Holy Light may be a reference to the Warcraft series' Church of the Holy Light, a religion that retconed earlier lore (which was later explained as an older religion) for the Warcraft religion of Humans. This is similiar to the change the Apostles of the Holy Light have made to their affiliates, the Children of Atom.
