Sean Seamus O'Flynn, Earl of Derry and loyal lieutenant and friend to Duke Alaric Morgan. Derry is fully human, but trusts Alaric enough to willingly allow the Deryni duke access to his mind, despite the abuses of Deryni power that Derry suffered while a prisoner of war in the clutches of the late King Wencit of Torenth.
Sister Rothana was a novice on the verge of taking permanent vows as a religious when she fell in love with Kelson Haldane during the Mearan War. Kelson returned those feelings and asked her to consider becoming his Queen once he returned from a quest in search of relics of Saint Camber, the Deryni saint responsible for restoring the Haldane line to its rightful rule over Gwynedd two centuries earlier, after years of despotic rule by Deryni from the neighboring Kingdom of Torenth. Unfortunately, Kelson and his friend Dhugal met with an accident and were lost and presumed dead. During this time, Prince Conall, Kelson's cousin, secretly committed a series of treasonous acts which led to him becoming the presumed heir to the throne. He persuaded Rothana to marry him, which she reluctantly agreed to do in hopes that as Queen of Gwynedd she might have the opportunity to carry out Kelson's dreams for his Kingdom. By the time Kelson and Dhugal returned to Rhemuth, the young bride was pregnant with Conall's child, and after Conall's execution, she felt she was no longer worthy of becoming Kelson's Queen. Kelson continued to try to persuade her to marry him, but to no avail. Three years later, she proposed the idea to Kelson that his cousin Araxie would make a suitable consort. Due to his need for an heir, he reluctantly agreed to pursue the match, only to be surprised by the discovery that he and Araxie were more compatible than he'd dare to dream, and that new love could flourish even in a marriage originally entered into by necessity. Sister Rothana began a new life with the Servants of Saint Camber, serving as a lay sister at the Schola of Saint Camber.
Father John Nivard, one of several young Deryni priests who were ordained by the Deryni bishop Denis Arilan during a time when Deryni seeking entry into the priesthood risked being burned at the stake if discovered. After serving in Arilan's bishopric of Dhassa for a time, he was transferred to Rhemuth Castle, where he serves as King Kelson's current confessor and also as the Royal Librarian.
Sister Helena, a lay sister with the Servants of Saint Camber, was born Elen Angharad ferch Ednyved in the neighboring Kingdom of Llannedd. Of full Deryni heritage, Sister Helena moved to the Kingdom of Joux to live with her mother's family when she reached young womanhood, so that she could receive formal training in the magical arts and also meet a suitable husband. She gained both Deryni knowledge and a husband, but her marriage was unhappy. Increasingly angry and bitter over Helena's barrenness, her husband became more and more abusive over the years before his death. After her husband's death, Helena took refuge at the Convent of Saint Jerome in Joux, seeking consolation and inner healing from her studies there, but after discovering that she had the rare Deryni gift of Healing, she moved to the Schola of Saint Camber in Rhemuth in hopes of learning how to use this gift. At the Schola, the Eleven Kingdoms' only other known Deryni Healers (including Alaric Morgan, Duncan McLain, and Dhugal MacArdry McLain) pooled their limited knowledge and newly-gained insights regarding this nearly lost art. Helena's unhappy experience with marriage has left her reluctant to consider a second husband, and her interest in scholarly pursuits has drawn her to remain part of the monastic life at the Schola as a magistra (teacher) of the magical arts. The deep friendship she has formed with the Schola's rector, Bishop Duncan, has also helped her heart to mend, despite the inherent challenges of keeping their close bond within the bounds of propriety.
