Gillian

Gillian is a woman who lives on Windfall Island in.

Biography
Gillian works at Windfall's Cafe Bar. Her initial impression of Zunari, who runs the stall below her cafe, is that he is a braggart and she complains of being tired of constantly hearing about his incredible treasure. When she learns that he has gifted his treasure to a strange boy for no apparent reason, her opinion of him completely changes and she calls him a "great person."

The Fishman near Rock Spire Isle mentions that he and Gillian used to stare at the Windfall Lighthouse together.
