Zeel was born in Zebak city, where she lived during her early childhood. When she was four years old her parents tried to flee with her from the Zebak land by boat so that Zeel could live in freedom and safety, but were unfortunately killed in the attempt. Zeel was later washed-up on the Maris shore and found by the Travellers, who took her in and raised her as their own.
After hearing that Rowan is in danger and needs her Zeel flies to Rin, where she is met by Lann. Lann gives her the fourth coat which destined for her, as she is meant to accompany Rowan up the mountain. Zeel then flies to meet Rowan, Shaaran and Norris, who are surprised at her arrival. Out of fear for her life, for their quest to defeat the Ice Creepers will be dangerous and life-threatening, Rowan tries to persuade her to return to Maris, but Zeel will not be moved.
Zeel is described as being almost as tall as Marlie, with straight eyebrows and pale blue eyes. She is described as looking sterner than the rest of the Travellers, possibly due to her Zebak descendance. Her hair is long, curly, tangled and brown and threaded with flowers, feathers and ribbons. Like most Travellers Zeel's feet are brown walking on the ground barefoot. She wears loose bright silk clothes.
