Early Life
Because of the one child law, Aurora Blake was forced to keep her second pregnancy a secret. Octavia was born outside of a medical center and without a doctor. A seven year old Bellamy Blake was the only help Aurora had at the scene of the child's birth. After the child was born, Aurora told Bellamy to name her. Bellamy named her Octavia after Emperor Augustus' sister. Aurora told Bellamy that Octavia was his responsibility.

As Octavia grew so did her curiosity of the outside world. Octavia wished to leave her home, but was unable to do so being an unregistered child. When the Ark performed surprise inspections Octavia was forced to hide under the floor.

When Octavia was fifteen, Bellamy found a way for Octavia to see the outside world. The Ark was holding a masquerade dance in honor of Unity Day. However, while at the dance, a solar flare occurs and the guard shows up demanding everyone take off their masks and show their ID chips. Bellamy tries to get his sister out, but is caught by Commander Shumway, whom asks who Octavia is. Bellamy begs Commander Sumway to let her go, but he refuses stating Bellamy is not a guardsman yet. Octavia is arrested and taken to lockup. Bellamy loses his rank as a cadet in the guard and is given a new position as a sanitation worker.

One year later, Commander Shumway comes to Bellamy and tells him that 100 prisoners are being sent to the ground. Among them is his sister. He offers to get Bellamy onto the ship to be with his sister, provided he kills the Chancellor.
