Backstory
Anyanka 'Anya Jenkins' was born as Aud in the 9th century in Sjornjost, a small Scandinavian village. Aud grew up raising rabbits and became an outsider in her community, which dismissed her as "odd", because of her strange mannerisms and out-of-the-ordinary ideas (such as not wanting to sell the rabbits she had been breeding, but instead giving them to people in the village as gifts). She eventually falls in love with the boorish Olaf, a Viking warrior who enjoys hunting trolls and drinking at the bar. In 880, a furious Aud discovers that Olaf has cheated on her with a bar matron named Rannveig, and takes her revenge on him by using magic to transform him into a troll. Aud had previously used magic against her past lovers as well, casting spells to create boils on the penis, for example, but this act of vengeance against Olaf attracts the attention of the demon D'Hoffryn, who offers to transform her into a vengeance demon for scorned women. D'Hoffryn gives Aud the new name Anyanka, Patron Saint Of The Women Scorned, and a pendant which gives her the power to grant wishes.  Around 1199, Anyanka goes to the Koskov valleys above the Urals to curse an unfaithful man. She witnesses a sorcerer's Ascension into pure demon form. The death and carnage -- only a few people survive -- shock even her. Around 1580, Anyanka meets (and dates) Dracula, and later is in Salem, Massachusetts, during the witch trials of 1692.  In the 19th century, Anyanka becomes a close friend and fierce competitor of the vengeance demon known as Halfrek, whose specialty is avenging wronged children. They spend time together during the Crimean War. Anyanka impresses "Hallie" with a granted wish in Saint Petersburg, Russia, that sparks a revolution in 1905. In 1914, Anyanka travels to Chicago, Illinois, to exact vengeance on a man named Stewart Burns, turning him into a demon and sending him to a hell dimension to be tortured for all eternity.
