THE BOOK: See also Sinsar Dubh (she-suh DOO). A fragment of the Unseelie King himself, a sentient, psychopathic book of enormous, dark magic created when the king tried to expel the corrupt arts with which he’d tampered, trying to re-create the Song of Making. The Book was originally a nonsentient, spelled object but in the way of Fae it evolved and over time became sentient, living, conscious. When it did, like all Unseelie created via an imperfect Song, it was obsessed by a desire to complete itself, to obtain a corporeal body for its consciousness, to become like others of its kind. It usually presents itself in one of three forms: an innocuous hardcover book; a thick, gilded, magnificent ancient tome with runes and locks; or a monstrous amorphous beast. It temporarily achieves corporeality by possessing humans, but the human host rejects it and the body self-destructs quickly. The Sinsar Dubh usually toys with its hosts, uses them to vent its sadistic rage, then kills them and jumps to a new body (or jumps to a new body and uses it to kill them). The closest it has ever come to obtaining a body was by imprinting a full copy of itself in Mac as an unformed fetus while it possessed her mother. Since the Sinsar Dubh’s presence has been inside Mac from the earliest stages of her life, her body chemistry doesn’t sense it as an intruder and reject it. She can survive its possession without it destroying her. Still, the original Sinsar Dubh craves a body of its own and for Mac to embrace her copy so that it will finally be flesh and blood and have a mate.
THE BOX: Little is known of this Unseelie Hallow. Legend says the Unseelie King created it for his concubine.
THE HAVEN: High Council and advisors to the Grand Mistress of the abbey, made up of the seven most talented, powerful sidhe-seers. Twenty years ago it was led by Mac’s mother, Isla O’Connor, but the Haven got wind of Rowena tampering with black arts and suspected she’d been seduced by the Sinsar Dubh, which was locked away beneath the abbey in a heavily warded cavern. They discovered she’d been entering the forbidden chamber, talking with it. They formed a second, secret, Haven to monitor Rowena’s activities, which included Rowena’s own daughter and Isla’s best friend, Kayleigh. The Haven was right, Rowena had been corrupted and ultimately freed the Sinsar Dubh. It is unknown who carried it from the abbey the night the Book escaped or where it was for the next two decades.
IFP: Interdimensional Fairy Pothole, created when the walls between Man and Faery fell, and chunks of reality fragmented. They exist also within the network of Silvers, the result of Cruce’s curse. Translucent, funnel-shaped, with narrow bases and wide tops, they are difficult to see and drift unless tethered. There is no way to determine what type of environment exists inside one until you’ve stepped through, extreme climate excepted.
IRON: Fe on the periodic table, painful to Fae. Iron bars can contain nonsifting Fae. Properly spelled iron can constrain a sifting Fae to a degree. Iron cannot kill a Fae.
MACHALO: Invented by MacKayla Lane, a bike helmet with LED lights affixed to it. Designed to protect the wearer from the vampiric Shades by casting a halo of light all around the body.
NULL: A sidhe-seer with the power to freeze a Fae with the touch of his or her hands (MacKayla Lane has this talent). While frozen, a Nulled Fae is completely powerless, but the higher and more powerful the caste of Fae, the shorter the length of time it stays immobilized. It can still see, hear, and think while frozen, making it very dangerous to be in its vicinity when unfrozen.
POSTE HASTE, INC.: A bicycling courier service headquartered in Dublin that is actually the Order of Sidhe-Seers. Founded by Rowena, she established an international branch of PHI in countries all over the world to stay apprised of all developments globally.
PRI-YA: A human who is sexually addicted to and enslaved by the Fae. The royal castes of Fae are so sexual and erotic that sex with them is addictive and destructive to the human mind. It creates a painful, debilitating, insatiable need in a human. The royal castes can, if they choose, diminish their impact during sex and make it merely stupendous. But if they don’t, it overloads human senses and turns the human into a sex addict, incapable of thought or speech, capable only of serving the sexual pleasures of whomever is their master. Since the walls fell, many humans have been turned Pri-ya and society is trying to deal with these wrecked humans in a way that doesn’t involve incarcerating them in padded cells, in mindless misery.
SHAMROCK: This slightly misshapen three-leaf clover is the ancient symbol of the sidhe-seers, who are charged with the mission to See, Serve, and Protect mankind from the Fae. In Bloodfever, Rowena shares the history of the emblem with Mac: “Before it was the clover of Saint Patrick’s trinity, it was ours. It’s the emblem of our Order. It’s the symbol our ancient sisters used to carve on their doors and dye into banners millennia ago when they moved to a new village. It was our way of letting the inhabitants know who we were and what we were there to do. When people saw our sign, they declared a time of great feasting and celebrated for a fortnight. They welcomed us with gifts of their finest food, wine, and men. They held tournaments to compete to bed us. It is not a clover at all, but a vow. You see how these two leaves make a sideways figure eight, like a horizontal Möbius strip? They are two S’s, one right side up, one upside down, ends meeting. The third leaf and stem is an upright P. The first S is for See, the second for Serve, the P for Protect. The shamrock itself is the symbol of Eire, the great Ireland. The Möbius strip is our pledge of guardianship eternal. We are the sidhe-seers and we watch over Mankind. We protect them from the Old Ones. We stand between this world and all the others.”
SIFTING: Fae method of travel. The higher ranking, most powerful Fae are able to translocate from place to place at the speed of thought. Once they could travel through time as well as place, but Aoibheal stripped that power from them for repeated offenses.
SINSAR DUBH: Originally designed as an ensorcelled tome, it was intended to be the inert repository or dumping ground for all the Unseelie King’s arcane knowledge of a flawed, toxic Song of Making. It was with this knowledge he created the Unseelie Court and castes. The book contains an enormous amount of dangerous magic that can create and destroy worlds. Like the king, its power is nearly limitless. Unfortunately, as with all Fae things, the Book, drenched with magic, changed and evolved until it achieved full sentience. No longer a mere book, it is a homicidal, psychopathic, starved, and power-hungry being. Like the rest of the imperfect Unseelie, it wants to finish or perfect itself, to attain that which it perceives it lacks. In this case, the perfect host body. When the king realized the Book had become sentient, he created a prison for it, and made the sidhe-seers — some say by tampering with their bloodline, lending a bit of his own — to guard it and keep it from ever escaping. The king realized that rather than eradicating the dangerous magic, he’d only managed to create a copy of it. Much like the king, the Sinsar Dubh found a way to create a copy of itself, and planted it inside an unborn fetus, MacKayla Lane. There are currently two Sinsar Dubhs: one that Cruce absorbed (or became possessed by) and the copy inside MacKayla Lane that she refuses to open. As long as she never voluntarily seeks or takes a single spell from it, it can’t take her over and she won’t be possessed. If, however, she uses it for any reason, she will be obliterated by the psychopathic villain trapped inside it, forever silenced. With the long-starved and imprisoned Sinsar Dubh free, life for humans will become Hell on Earth. Unfortunately, the Book is highly charismatic, brilliant, and seductive and has observed humanity long enough to exploit human weaknesses like a maestro.
