The 'Air Priestess' of the Air Temple in Aeropolis. She isn't the Guardian of the crystal, but merely serves as a defender and maintainer of the magical portal to the true Air Temple, high in the sky; a job necessary when the portal is in the middle of a heavily-populated city.
She isn't originally from Aeropolis. Instead, she was born in the north somewhere, on Hadris. She spent her early years as an adventurer, travelling with Social Fox at some point. She later settled down and had a child, who she enrolled in the Royal Guard of Goznor when she was old enough. Her husband is deceased.
She doesn't allow Mardek's group to take the Air Crystal, saying that it is already well-protected.
- Gail's name contains two references to her Air-elemental nature. Her first name is a homonym for gale, a strong wind. Her last name, Quall, is also a type of wind.
