Gillian is an orphan from the Grand Valley orphanage. She was transferred to the Goldy Pond hunting ground as potential prey, where she witnessed the death of her beloved sister by the hands of the Poachers. Determined for vengeance, Gillian joined the Goldy Pond Resistance, where she ended up in charge of the provisions.

Gillian is a high-spirited and outgoing teenage girl, which thus made her stood out from the rest of the members of the Goldy Pond Resistance, whom are mostly serious in nature. This was evident when she and Sandy are the liveliest among the team members when [Violet](https://anilist.co/character/126490/Violet) introduced them to [Emma](https://anilist.co/character/121725/Emma).
