|“||I was a dreamer born into the Court of Nightmares.||”|
–Morrigan, A Court of Mist and Fury
Mor is a High Fae born in the Hewn City, in Court of Nightmares of the Night Court. While she was growing up, she was strong and powerful and her family could feel that she was stronger than most in the family. She grew up fearing to be sold by her family, as High Faes value female virgins.
Several days after her seventeenth birthday, she bled for the first time. Her power awakened, making even the mountain of the Court of Nightmares tremble. This was considered by her family as a bargaining gift, making Mor more desirable for powers and her virginity.
When Mor was sold into marriage to Eris Vanserra, the eldest son of the High Lord of the Autumn Court, Rhysand took her to an Illyrian camp where he was stationed. Once there, she willingly lost her virginity to Cassian, in order to escape her arranged marriage to Eris.
On the night when Rhysand, his mother, and Azriel left the camp, Cassian and Mor made love. When Rhysand heard, he fought with Cassian.
When Mor returned to the Court of Nightmares, Eris heard what she did with an Illyrian warrior. He told her that she had no value to him. Mor's family tortured her. She was dumped in the Autumn Court with a note nailed to her belly stating that she was Eris's problem. Azriel rescued her and brought her to Rhysand.
Some time in the war between humans and fairies, Mor allied with the humans and helped the Mortal Queens forge the Treaty.
When Rhysand became the High Lord of the Night Court, she was appointed his third-in-command and overseer of the Court of Nightmares and the Court of Dreams, running both the Hewn City and Velaris. She is also a member of Rhysand's Inner Circle.
Mor is described as beautiful, with a curvy body, brown eyes, and golden hair. She also has tan skin and smells like citrus and cinnamon.
Her abilities are not described in detail in the book, yet it mentions that she can winnow. However, she mentions that her power is Truth, and she is seen healing Azriel at the end of A Court of Mist and Fury.
It is mentioned that Azriel fell in love with Mor the moment he saw her strutting into the Illyrian war camp over five hundred years ago. Mor confesses to Feyre that the reason their relationship has remained stationary is because Mor prefers females over males. Therefore, she is not interested in Azriel romantically and loves him like a brother. However, she chooses to withhold such information from Azriel, as she is afraid of what the Inner Circle would think of her and still experiences self-hatred for who she is.
After losing her virginity to Cassian, they have not been together ever since. However, they remain good friends.
After admitting to Feyre that she prefers females, over males, she confessed that there was once a woman she had truly loved. Andromache was a Mortal Queen whom Mor had had a secret relationship with in the past. Thinking that Andromache had a duty to carry out her bloodline, Mor left her after the last battle. When she wanted to return to Andromache, the Wall was established. For three years, she fought to cross it, to go and be with her lover but when she finally did, Andromache was married to a man, had an infant child, and another on the way. Mor turned away and never came back. Andromache gave birth to a total of five children and died in her bed, old and safe. Mor recognized her descendant in the eyes of the golden Mortal Queen, when she met the young woman many years later.
Mor has had no serious relationships since Andromache. She took both male and female lovers, though she was implied to have been disgusted sleeping with males. The females were kept secret, but her relationships with males were for everyone to see since she wanted Azriel to know that she wasn't interested. Still, Azriel never seemed to stop loving Mor from afar.
Mor is the first member of the Inner Circle who Feyre meets—with the exception of Rhysand himself—and is kind and welcoming to her, though Feyre is initially hesitant to return the sentiment. The two grow closer later on and become good friends. This eventually leads to Feyre being the first person Mor comes out to as lesbian.
