DANIELLE “THE MEGA” O’MALLEY: Main character. An enormously gifted, genetically mutated sidhe-seer with an extremely high IQ, super strength, speed, and sass. She was abused and manipulated by Rowena from a young age, molded into the old woman’s personal assassin, and forced to kill Mac’s sister, Alina. Despite the darkness and trauma of her childhood, Dani is eternally optimistic and determined to survive and have her fair share of life plus some. In Shadowfever, Mac discovers Dani killed her sister, and the two, once as close as sisters, are now bitterly estranged.
ROWENA O’REILLY: Grand Mistress of the sidhe-seer organization until her death in Shadowfever. Governed the six major Irish sidhe-seer bloodlines but rather than training them, controlled and diminished them. Fiercely power-hungry, manipulative, and narcissistic, she was seduced by the Sinsar Dubh into freeing it. She ate Fae flesh to enhance her strength and talent, and kept a lesser Fae locked beneath the abbey. Dabbling in dangerous black arts, she experimented on many of the sidhe-seers in her care, most notably Danielle O’Malley. In Shadowfever she is possessed by the Sinsar Dubh and used to seduce Mac with the illusion of parents she never had, in an effort to get her to turn over the only illusion amulet capable of deceiving even the Unseelie King. Mac sees through the seduction and kills Rowena.
ISLA O’CONNOR: Mac’s biological mother. Twenty-some years ago Isla was the leader of the Haven, one of seven trusted advisors to the Grand Mistress in the sacred, innermost circle of sidhe-seers at Arlington Abbey. Rowena (the Grand Mistress) wanted her daughter, Kayleigh O’Reilly, to be the Haven leader, and was furious when the women selected Isla instead. Isla was the only member of the Haven who survived the night the Sinsar Dubh escaped its prison beneath the abbey. She was briefly possessed by the Dark Book but not turned into a lethal, sadistic killing machine. In the chaos at the abbey, Isla was stabbed and badly injured. Barrons tells Mac he visited Isla’s grave five days after she left the abbey, that she was cremated. Barrons says he discovered Isla had only one daughter. He later tells Mac it is conceivable Isla could have been pregnant the one night he saw her and a child might have survived given proper premature birth care. He also says it is conceivable Isla didn’t die, but lived to bear another child (Mac) and give her up. Barrons theorizes Isla was spared because the sentient evil of the Sinsar Dubh imprinted itself on her unprotected fetus, made a complete second copy of itself inside the unborn Mac and deliberately released her. It is believed Isla died after having Mac and arranging for her friend Tellie to have both her daughters smuggled from Ireland and adopted in the States, forbidden ever to return to Ireland.
AUGUSTA O’CLARE: Tellie Sullivan’s grandmother. Barrons took Isla O’Connor to her house the night the Sinsar Dubh escaped its prison beneath Arlington Abbey over twenty years ago.
KAYLEIGH O’REILLY: Rowena’s daughter, Nana’s granddaughter, best friend of Isla O’Connor. She was killed twenty-some years ago, the night the Sinsar Dubh escaped the abbey.
NANA O’REILLY: Rowena’s mother, Kayleigh’s grandmother. Old woman living alone by the sea, prone to nodding off in the middle of a sentence. She despised Rowena, saw her for what she was and was at the abbey the night the Sinsar Dubh escaped more than twenty years ago. Though many have questioned her, none have ever gotten the full story of what happened that night.
KATARINA (KAT) MCLAUGHLIN (MCLOUGHLIN): Daughter of a notorious crime family in Dublin, her gift is extreme empathy. She feels the pain of the world, all the emotions people work so hard to hide. Considered useless and a complete failure by her family, she was sent to the abbey at a young age, where Rowena manipulated and belittled her until she became afraid of her strengths and impeded by fear. Levelheaded, highly compassionate, with serene gray eyes that mask her constant inner turmoil, she wants desperately to learn to be a good leader and help the other sidhe-seers. She turned her back on her family mafia business to pursue a more scrupulous life. When Rowena was killed, Kat was coerced into becoming the next Grand Mistress, a position she has felt completely unfit for. Although imprisoned beneath the abbey, Cruce is still able to project a glamour of himself, and in dreams he seduces Kat nightly, shaming her and making her feel unfit to rule, or be loved by her longtime sweetheart Sean O’Bannion. Kat has a genuinely pure heart and pure motives but lacks the strength, discipline, and belief in herself to lead.
JO BRENNAN: Midtwenties, petite, with delicate features and short, spiky dark hair, she descends from one of the six famous Irish bloodlines that can see the Fae (O’Connor, O’Reilly, Brennan, the McLaughlin or McLoughlin, O’Malley, and the Kennedy). Her special talent is eidetic or sticky memory for facts but unfortunately by her midtwenties she has so many facts in her head, she can rarely find the ones she needs. She has never been able to perfect a mental filing system. When Kat clandestinely dispatches her to get a job at Chester’s so they can spy on the Nine, Jo allows herself to be coerced into taking a waitressing job at the nightclub by the immortal owner, Ryodan, and when he gives her his famous nod, inviting her to his bed, she’s unable to resist even though she knows it’s destined for an epic fail.
PATRONA O’CONNOR: Mac’s biological grandmother. Little is known of her to date.
Little is known about them. They are immortals who were long ago cursed to live forever and be reborn every time they die at precisely the same unknown geographic location. They have an alternate beast form that is savage, bloodthirsty, and atavistically superior. It is believed they were originally human from the planet Earth but that is unconfirmed. There were originally ten, counting Barrons’s young son. The known names they currently go by are Jericho Barrons, Ryodan, Lor, Kasteo, Fade. In Burned we discover one is named Daku. There’s a rumor that one of the Nine is a woman.
JERICHO BARRONS: Main character. One of a group of immortals who reside in Dublin, many of them at Chester’s nightclub, and is their recognized leader, although Ryodan issues and enforces most of Barrons’s orders. Six feet three inches tall, black hair, brown eyes, two hundred forty-five pounds, date of birth October 31, allegedly thirty-one years old, his middle initial is Z, which stands for Zigor, meaning either “the punished” or “the punisher” depending on dialect. He is adept in magic, a powerful warder, fluent in the druid art of Voice, an avid collector of antiquities and supercars. He despises words, believes in being judged by one’s actions alone. No one knows how long the Nine have been alive, but references seem to indicate in excess of ten thousand years. If Barrons is killed, he is reborn at an unknown location precisely the same as he was the first time he died. Like all of the Nine, Barrons has an animal form, a skin he can don at will, or if pushed. Barrons had a son who was also immortal, but at some point in the distant past, shortly after Barrons and his men were cursed to become what they are, the child was brutally tortured and became a permanent, psychotic version of the beast. Barrons kept him caged below his garage while he searched for a way to free him, hence his quest to obtain the most powerful book of magic ever created, the Sinsar Dubh. He was seeking a way to end his son’s suffering. In Shadowfever, Mac helps him lay his son to final rest by using the ancient Hunter, K’Vruck, to kill him.
