Order of Mysteries

The Order of Mistresses of Mystery, or Order of Mysteries, is a faction that was founded by Shannon and Frederick Rivers in Appalachia after the War.

Background
The Rivers adopted multiple orphaned girls after the Great War and provided them food, shelter, and training to survive. The Order was created so that they could be heroes for Appalachia, based on the Mistress of Mystery from the Silver Shroud comics. The combat style of the Order was based on the same hero, focusing on reconnaissance, stealth, and cunning.

Frederick was the only male in the group but wasn't ranked and instead had the role of being their technological specialist. He designed and built the Order's equipment that was based on the fictional equipment of the Mistress of Mystery. He also reprogrammed the RobCo mainframe Cryptos to support the Order by automating initiate registration, mentor assignment, and mission assignment. He also invented a fabricator to automate the creation and repair of the Order's equipment.

The Order was destroyed after Olivia Rivers, daughter of the founders, sold out the Order to Brody, a raider. Later, she revealed her betrayal to her mother and fought and killed her at Seneca Rocks. Olivia was the last member prior to 2102 before she was double crossed and killed by Brody.

Headmistress
The Headmistress was the leader of the Order and embodiment of the Mistress of Mystery. She assigned missions to Mistresses and Seekers. Shannon Rivers was the only Headmistress until sometime before 2102.

Mistress of Novices
The Mistress of Novices was the second in command and assigned missions to novices. In the absence of the Headmistress she also assigned missions to Mistresses and Seekers. Eve Devoir was the last to hold the position before 2102.

Mistress of Mystery
Mistresses were full members of the Order who reported directly to the Headmistress or the Mistress of Novices in her absence.

Seekers
Seekers studied advanced combat tactics and reported directly to the Headmistress or Mistress of Novices. When they demonstrated "mastery of stealth, infiltration, combat, and tactics" by completing a "mission worthy of the true Mistress of Mystery," they could apply to be promoted to the rank of Mistresses of Mystery.

Novices
Novices continued to train under their mentor and were assigned missions by the Mistress of Novices. When they completed a series of capstone missions, they could become Seekers.

Initiates
Initiates were the newest members and worked with a mentor as they trained. They were unable to accept to missions until they were promoted to Novice when their mentors saw fit. Initiates were recruited by other members and were given a veil to enter the headquarters.

Technology
Each piece of armor, weapon, and tools used by the order were based on those used by the fictional character Mistress of Mystery. These tools were known as the Regalia of Mystery and members would receive the equipment as they were promoted. The Regalia included:
 * Veil of Secrets - a veil that protects identity and also against gas, smoke, and fumes.
 * Garb of Mysteries - a formal dress that was redesigned for mobility and stealth.
 * Phantom device - a stealth tool that creates a smoke screen for rapid escape.
 * Blade of Bastet - a sword.
 * Voice of Set - a modified .44 revolver that could fire smoke and electromagnetic bullets
 * Eye of Ra - a jeweled brooch.

Appearances
Order of Mysteries appears in Fallout 76.
