Orphan of mysterious origins, Connie took her in as a child and taught her all she knew about airships, she has been with her since.
Her past is mostly unknown, but her overall appearance and capabilities makes it clear that she's a member of the heavily persecuted Pucelle specie.
Her excellent eyesight and her astounding ability in messing with machines make her an irreplaceable member of the Urmensch's crew.

She's actually princess Shela Rom, descendant princess tied by blood to the first emperor.
