Appearance and Character
Leoni is described as having dark brown skin, long black hair, which she wears in twists, and brown eyes. She wears topaz and amethyst gems in her hair, which symbolize her mother and Aditi Hilli. She is a very happy and bubbly girl, which contrasts with Adrik's sullen attitude. She is also very daring and quick on her feet, as she assists Nina in blowing up the factory run by Jarl Brum. At the end of King of Scars, the citizens declare Leoni and Adrik the new saints, where she is given the name 'Sankta Leoni of the Waters'.
When Leoni was a child, she accidentally ingested contaminated water. Jesper Fahey's mother, Aditi Hilli, saved Leoni's life by drawing the poison out of Leoni and into herself. This resulted in the death of Jesper's mother, which made Leoni decide to devote her life to helping other people.
