Sister Harper

Sister Harper was a member of the Children of Atom in 2287.

Background
High Confessor Tektus had doubts about the loyalty of Brother Alders, not to his faith, but to Tektus himself, rather than their former leader Confessor Martin. In contrast, the high confessor had great confidence in the loyalty of another member, Sister Harper. Although Grand Zealot Richter disagreed about Alders, and tried to dissuade Tektus, the high confessor, in his paranoia, decided to have a test of "devotion" between Alders and Harper. Tektus had Richter bring Alders and Harper outside, ordering them to kill one another.

Harper was victorious in this exchange, as Alders hesitated, not wishing to end Harper's life and frantically questioning the order. Harper killed Alders without hesitation, "proving" her loyalty, asking if there was anything else required of her before returning, unfazed, to the Nucleus.

Appearances
Sister Harper is mentioned only in the Fallout 4 add-on Far Harbor.
