Gunvor was the adopted daughter of Ramiel of Geirsa and one of the Twelve Luminaries. She was born in Saurjar. Her mother died when she was only a toddler, and her real father is unknown. There is speculation that her father might have been Lucter, but this is not sure.
Gunvor was raised by Ramiel and trained by him alongside his students. Being a senior student, she sometimes assisted her adoptive father in teaching his students, one of whom was Luminary Niall, whom later matched up with her in combat skills and became her regular training partner and friend.
