Females deemed pure are offered the chance to be guided and trained under specific virtues. Pure means that they are virgins, kindhearted, and free of eldritch blood. They will undergo rigorous training alongside agents in the ways of combat as well as intel gathering, tracking, medicine and more. Like agents, they will be given the option to specialize in their training when the time comes. In most cases, sisters specialize in training that will support their team both on and off the field.
When a sister is ready, she will choose the god she will call upon to bestow gifts of magic. The sister will perform acts of prayer, services, and more to appease the god, or in rare cases gods. She will strengthen their bond through various acts and improve her skills she was granted under a Matron Mother.
A Matron Mother, or simply Mother, are women who have completed a ritual given to them by their god. Each Mother undergoes their own unique ritual ceremony catered to them by the beings they worship. Through this ceremony, they will be given a holy book by their god completing an old binding contract created years ago when magic first appeared within these lands.
Once a Mother has their assigned book, they will be able to tap into the magic that has been buried within themselves and within the lands. Their magic is unique to them. Their personalities, emotions, bloodline, and more will affect the incantations and symbols that will be scrawled across the pages. With the book a Mother is deemed to be an extremely powerful individual. No book is the same, but all books are considered dangerous in the wrong hands. Once a book is created it can be stolen and used against the Mother if the thief is able to decipher the words scrawled upon the pages. The mother must protect these books and maintain their connections to their gods for their powers. Most will do this by establishing themselves within a place of worship such as a Cathedral.
As a mother, they are in charge of training the next generation of sisters. All Mothers were once sisters, but not all sisters will be mothers.
Some sisters can defect as agents and still retain their connection to their chosen gods. Sisters who do not have a god to call upon will automatically be defected as agents if they chose to remain within the Dominion.
When choosing their god, a sister can hear and respond to the voice of an eldritch. When this occurs, the sister must be detained. In the best-case scenario, they are reclassified as an eldritch variant and will be given an eldritch class level based on their threat potential. If compatible, they may proceed with the sisterhood training. In the worst-case scenario, the sister will be terminated on site.
Further knowledge about the sisters and the books is kept confidential amongst those who bare the title. An outsider can gain further knowledge if a Mother has granted permission and bestows the information to the individual.
