A very beautiful woman who is very skilled with a blade. She is recognizable as the only Reaper in the Night Church Army to have hair. She is very influential and can be commonly seen with Brother Alexi.
Before Mother Rose joined the Night Church, she was a mother to Riot, once known as Margaret, later turned Sister Margaret when she became a reaper. Saint John rescued her after The Fall. She convinced her husband to join the reapers, as well as her daughter.
Mother Rose died shortly after the attack on the Shrine of the Fallen, at the hands of the zombified Brother Alexi. She was most likely killed again during the attack on Sanctuary. Riot shut down emotionally upon seeing her undead mother, who stared back at her.
