Mist was born in Gallia, and spent her early years in this country with her family. During this time, she is entrusted to be the keeper of a bronze medallion by her father. Unbeknownst to her, she is the only beorc who can hold the medallion without going berserk due to the forces of Order and Chaos being unusually balanced in her heart. She often sings a lullaby taught to her by her mother to the Medallion, which, in actuality, is the Galdr of Release. After the death of her mother, Mist moves to Crimea with her remaining family members, where her father starts the Greil Mercenaries.
