Freya Mikaelson (Elder Futhark: ᚠᚱᛖᛃᚨ ᛗᛁᚲᚨᛖᛚᛋᛟᚾ) is a powerful witch and also a main character on The Originals. Introduced as a recurring character in the second season, she is the firstborn child of Mikael and Esther, the elder sister of Finn, Elijah, Kol, Rebekah, and Henrik, the maternal older half-sister of Niklaus Mikaelson and the paternal aunt of Hope Mikaelson.
Esther told Mikael that Freya had died of the plague while he was off hunting, when in fact her aunt Dahlia took her as payment for performing a fertility spell using Dark Magic that would allow Esther to have children. Dahlia allowed Freya to live planning to use her to brand a new form of power which she would absorb from the powerful Freya, casting a spell on her that causes her to hibernate for a hundred years to preserve her youth and to only age for a year upon awakening which is also presumably what Dahlia has done to preserve herself as well. Freya escaped from under Dahlia's wing and fled from her powerful aunt.
Centuries later, desperate to find out more about her family, she traveled to New Orleans in 1914 where she attended a Christmas party thrown by her siblings. Attending as her brother, Kol's date, she was witness to Klaus's cruelty when he staked Kol in front of the entire party. Freya then puts herself in a glass coffin in the Dowager Fauline Cottage where she then repeated her hibernation cycle until present day December 31, 2012.
Entering a deep sleep that lasted a century, she awoke 100 years later where she discovered that her sister, Rebekah, had been imprisoned in the Asylum in the body of a young witch. Posing as an inmate, she witnessed Rebekah's confrontations with the Kindred and Cassie's betrayal. Using her magic, Freya saved Rebekah from the Kindred and broke the spell on the Asylum, freeing herself and Rebekah.
When Freya reunites with her brother Finn, he informs her of Hope's life, which inspires Freya (who wishes to take revenge against Dahlia for the deaths of her lover and son) so she can kill her as Dahlia would come for her niece, so she affiliates herself with her siblings. In the end of hard long magical struggle (resulting in the death of both her parents), Freya and her younger siblings finally managed to defeat Dahlia, with Freya's finally winning her younger brothers trusts (especially Niklaus), and moving into their house as Hope's caretaker and an official Mikaelson sibling.
After a few months of peace in the supernatural community in NOLA, troubles started again with the arrival of Lucien Castle, Klaus' first progeny, and his warnings of war between the sirelines, and so, Freya's enormous magical powers were needed again to protect her family from harm.
After the completion of the prophecy foretelling the downfall of her family, it seemed as though the entire family is going to die. She was poisoned, her brothers bitten by Marcel, and Rebekah hexed. Seeing no other choice in saving her family, Freya used Klaus as an anchor to a spell similar to the one Dahlia had cast on her to keep her breathing for a thousand years. Freya also created a Chambre de Chasse as she wanted her family to be together as they wait for Hayley to find cures for all of them.
Freya is a member of the Mikaelson Family and an unnamed Witch Family.
