Mother Andolça de Salinas

Original founder of the Sisterhood, and one that informs its culture to this day.
  Originally an ordained nun in Spain, she found her calling when a local street gang attempted to break into her convent and take advantage of the nuns present and rob the place blind.
  With skill she had never shown before, she managed to disarm one of the criminals and fight back, inspiring several other nuns to do the same. The gangers were driven off after suffering several casualties, and from there the idea of the Sisterhood would slowly spin to life.
  At first those nuns, lead by Salinas, went on a crusade across their home down, wiping out several street gangs before the others were alerted by the wave of violence. The police were hesitant to stop literal nuns from their purpose, and in the end the nuns stood victorious with their town secured.
  Prospective recruits quickly started to flood the convent, rapidly expanding the numbers of the church and giving them the numbers needed to expand to neighboring towns and try the same thing again. When that worked, they grew farther and did it again, and again, each time lead by Salinas.
  Eventually, when the Catholic Church attempted to shut her down for the large amount of death that her crusade had caused, she left the church and brought all of her followers with her. From there, she set up the organization that eventually became the Sisterhood.
