Mother Isolde

Mother Isolde is the leader of the Church of the Children of Atom branch located in the Commonwealth in 2287.

Background
Mother Isolde leads a group of non-hostile Children of Atom. She resides with fellow Children of Atom within the Crater of Atom, forming the sole human presence within the Glowing Sea. She is concerned about Brian Virgil's presence nearby, which is seen as an affront to Atom by some of the followers.

Quests

 * The Glowing Sea: Mother Isolde will provide the Sole Survivor information about Brian Virgil's whereabouts, in his nearby laboratory.

Other interactions
There are further dialogue options to learn more about why she and the other followers are in the Glowing Sea, how they survive in the radiation and generally about the Church of the Children of Atom.

If the player has joined the Children of Atom in Far Harbor, a new dialogue option will appear when first speaking to her. The player explains that they too are a Child of Atom, and she will accept this as truth, though she will be slightly suspicious about it.

Appearances
Mother Isolde appears only in Fallout 4.

Behind the scenes
Her name is possibly a reference to ISOLDE (an acronym for Isotope Separator On Line DEvice) which is an experimental infrastructure within the CERN complex of nuclear and particle physics experiments.
