Estelle was born in rural Rolent as the biological daughter of Cassius Bright and Rena Bright on 8-7-1186. When Estelle was 6, her mother was killed in the bombing of Rolent during the Hundred Days War, as she protected her in Rolent's clock tower. It was this traumatizing event that inspired Estelle to chose the path of a Bracer, to behold her mother's bravery and courageous like her mother.
Five years before the events of The Legend of Heroes: Trails in the Sky, when Estelle was 11, her father came home late with a wounded boy in his hands. The boy spoke nothing of his past, and Estelle and Cassius decide to adopt him.
The Legend of Heroes: Trails in the Sky
In present time, Estelle and Joshua were tutored by Scherazard Harvey and her father to becoming Bracers. Their initiation test is to search the Rolent Sewers and bring back the contents of a chest. The two succeed, and take various other tests about learning the tools of the trade (also effectively providing a tutorial for the player). Once they become Junior Bracers, Aina Holden reveals that two local boys went into the dangerous Esmelas Tower, and Joshua and Estelle move to rescue them. Once they do, Cassius intervenes, saving the four children.
Estelle is less than satisfied that she needed her father's help for the mission, but Joshua cheers her up. Later that night, Cassius reveals that must leave for some business in the Erebonian Empire, and when he leaves, Estelle and Joshua will take over the jobs he left for them in his absence.

Estelle, Joshua, and Renne reappear in the Crossbell State per Kevin's request to help fighting one of three Aion robots that guard Crossbell City from the intruders.
