Family line and all of that good stuff
Azazel
Was one of the chief Grigori, and a powerful fallen angel. Aaron, as atonement, 'shall cast lots' on two goats 'one for the Lord, and the other for the scapegoat' (Azazel). The name of Azazel (as supernatural power) means "goat-god". In Islamic demonology, Azazel was cast out of heaven for refusing to worship Adam and lusting for mortal women; he was soon thereafter stripped of his name and renamed to "Iblis", which means "despair". Azazel seeks to have a very powerful offspring, fused with human and demon blood, for the sake of power. But while he seeks to have offspring powerful enough to where he can annex through them, he wants a son. Unfortunately, it is said that he has been cursed by one of his own or another angel to have nothing but female Nephilim. As a result, no matter how hard he tries, all the women he impregnates bare daughters. He does not marry them, but takes them by force. Children of the fallen angel Azazel are gifted in the ability of prophecy, his "thorn curse", weaponry, teleportation, healing, and speed. He attacks women typically of noble or royal blood.
Anima, unfortunately, has not been told how she was conceived by her mother. Her mother wanted her to live a normal, happy life and did what she could to raise Anima loved, so she never told her daughter that she was raped by her father and her conception was the result of that. There is taint in Anima that may be from Azazel himself, because of her lack of rejection and embrace for her demonic power. She has nothing but curiosity for her father and what anyone knows about him. Unlike most Nephilim, Anima does not directly scorn the Grigori. Her affinity for weapons of her powers showcase that Anima can almost replicate her father's unnatural abilities.
Regina/ Gwenhwyfar
One of many of Anima's half-sisters. Regina is different because Regina happens to be one Anima hopes to find; she knows her to be the "Ovate of the Witch's Maw", nothing more. She doesn't know she's related to her, by any means. Regina, on the other hand, seems to be the opposite of Anima so far. Regina violently rejects her demonic heritage, avoids all conflict, and loathes any connection to her father. She is also misplaced Welsh royalty, the future wife of King Arthur. Anima seems to have more control than her sister, rarely goes on violent outbursts, unlike Regina, who frequently suffers from her unstable hunger. While she has solid control, Anima doesn't seem to be sound of mind like her older sister.
Fedelm Noíchride
Yep, one of many half-sisters. Fedelm is a very prominent seer as well as Druid in Ireland. She received weapons training in Alba (Scotland) as well as foreseeing the fall of Queen Medb. Fedelm was once the strongest of her kind, able to control her demonic powers as well as see into the future, making her both feared, respected, and especially resented by her own kind. Anima doesn't know of her existence, but Fedelm knows of her. Fedelm's fall resulted into her eating the flesh of her husband and finally being subdued by having her long hair cut. Anima's hair is ridiculously long, hinting at her strength, much like Fedelm's long, long hair. After her fall, Fedelm went into a quiet seclusion, still practicing to anyone. Fedelm's resistance to a violent uprising resulted in Regina's consultation and her being manipulated. When Regina vanished (actually being hauled off into the Otherworld) Fedelm was sought out and subdued. When Fedelm fell, the provocateurs of the uprising sought out Anima in terms to be her replacement. Unlike her sisters, Fedelm is warm, friendly, and even a bit of a smothering mother hen. Fedelm's powers are the weakest of the three, despite being the eldest.
