Arin was born the youngest of a prosperous family, but as the youngest of seven she didn't have a good future within the family. Instead, she dedicated herself to public service, entering the Nubian Special Materials Courier Corps as soon as she was old enough. Also known as the Sado-Masochist's Club, the job carried with it an extreme risk of interception. Arin was intercepted a total of eight times: with three instances of torture, and the last occurrance including a rape.
