Arcana's past is unknown. She was eventually found by Bailey before she even started her Mecha Racing Training. Arcana liked being with Bailey and stayed with her - despite her father, Conner Sterling, wanting Bailey to have a different Slug as her starter Slug to train with. Thankfully, Adam was able to get their father to understand and let Bailey keep Arcana. Arcana has been with Bailey since she started training and even was with Bailey when she found Vira - who Arcana became best friends with.
Once Bailey hit thirteen, Arcana went with her and Vira as she started the Mecha Races. Two years later, when Bailey was fifteen, and won a race, she was approached by Dr. Thaddius Blakk, who tried to recruited Bailey into his team due to her great racing skills. Bailey was quickly saved by the Shane Gang who took her to their hideout. There, Bailey, Vira, and Arcana were told about Dr. Blakk and his Ghouls and both quickly joined the team, after letting Piper know.
Arcana was going to be named Araña which was Spanish for "spider".
