Mother Curie III

 is the leader of a small cult living in the Holy Light Monastery in Springvale in 2277.

Background
Mother Curie III is a former Child of Atom and Megaton local who took Megaton's entire Aqua Pura shipment and began irradiating it and distributing it as holy water to fulfill her perceived religious calling to spread irradiation. In the basement of her newly adopted home she preaches to a pair of ghouls and in the lower part of the basement she stores vast amounts of Aqua Pura, along with her tame feral ghoul reaver named Atom's Champion and a less intimidating glowing one named Sun of Atom, both of which are her children.

Quests

 * Holy Water: The Lone Wanderer has the choice of persuading Curie to stop distributing the Holy Water to others, or stopping her by killing her and her followers.

Effects of player actions

 * Mother Curie III appears as a hostile feral ghoul reaver if Megaton is blown up after Broken Steel.
 * Mother Curie III is an extremely peaceful character, and does not become hostile if you killed Brother Gerard in order to enter the Monastery, 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.

Appearances
Mother Curie III appears in the Broken Steel add-on for Fallout 3.

Behind the scenes

 * Mother Curie III's name is a reference to Marie Curie, an early pioneer of the study of radiation who subsequently died of radiation poisoning.
