Mia is a Gunner from Castanica in the realm of Arborea, a world destroyed by the evil god Manahan. She used to be in service to the Valkyon Federation, and a rare breed in a world with mostly medieval technology. Mia was among those select who handle the massive arcane cannons - called Arcannons. Mia's interest in technology made her seek advancement, and with her uniquely engineered technology, she claims to be the first Cyberpunk from Arborea. She fled from Arborea and  ended up in Night City.
