Ellimere is a princess of the Old Kingdom, and heir to its throne. Her father is King Torrigan, and her mother is the Abhorsen. Like her mother, she attended school at Wyverley College, in Ancelstierre. Ellimere enjoys playing tennis, and asks her younger brother Sameth to make her some tennis racquets in order to teach her friends in the Old Kingdom how to play. At the second binding of Orannis, Ellimere stands for Dyrim. It can be assumed she is named after her mother's good friend who died binding Kerrigor.
Though she frustrates Sameth a great deal, generally by her attempts to find him a bride amongst her friends and their younger sisters, they also care about each other deeply, and Ellimere is willing to let Sameth rest from his Abhorsen duties if he feels the need to recover. She also had a good relationship with her aunt Lirael, even if she also tried to play matchmaker with her.
