Eve Devoir

 was a Mistress of the Order of Mysteries. Appointed Mistress of Novices in May 2086, instead of Shannon Rivers' daughter, Eve Devoir was everything Olivia was not: Dependable and organized, she was the perfect fit for the position to handle training and mission assignments. Olivia did not take the decision well, treating it as a slight - an insult - by her very own mother. It set in motion events that would lead to the collapse of the Order.
