Sapphire Scales

Sapphire Scales is a rare and incurable disease which causes sapphire-like stones to grow on the victim's skin.

Description
Saphhire Scales cause the victim's skin to grow sapphire-like stones, accelerated by exposure to natural light, whether sunlight or moonlight. It eventually leads to the victim's death. Although the growth of the stones can be stalled by avoiding light, the disease will eventually spread regardless, resulting in death within a few years. There is no known cure.

History
Ginny contracted the disease during her slavery in Mary Geoise. Because of this, she was released and returned to Sorbet Kingdom. However, due to prolonged exposure to sunlight during her trip back, she passed away soon after arriving.

Ginny's daughter Bonny later started developing the symptoms of the disease and was forced to stay indoors during her childhood. When Bonney was five years old, a doctor estimated that she had at best five years left to live. However, Bonney has currently exceeded this estimate by two years and no longer shows the symptoms of the disease.
