Sadie was born into a litter of 6 at Seal Back Bay north of Teekon. She was raised into the crew, taught how to scavenge and plunder at a young age. She was never given special treatment as a child, she didn't even know who her father was because her mother was raped blindly.

Sadie grew older and worked in the crew as a medic and plunderer. Her mother died when she was yearling due to birth issues, along with her litter. Sadie learned that day that life would never be the same, and she swore vengeance on the males who caused her mother's death. Sadie continued her hard work, though she was often abused during her work and treated like garbage. Sadie was forced into motherhood once, though all her children died due to the overwork of them in training.

It was then when she snapped. That very night, she snuck into the captain's quarters and killed him. It was a thrill to end his life, to know she gave her mother, her siblings, and her own children peace. With that, Sadie became the new leader of the Seal Back Bay. She reigned for the remaining two years before leaving, finding out that her crew was planning a mutiny. She managed to outroot a few beforehand, picking them off one by one before leaving in the middle of the night.

That's when she found Teekon. From there, she worked her tail off in finding a home. She found refuge in the Bonechewers, though seeing that it left, she left too. She had returned to Seal Back Bay, seeing that it was empty. She remained there for several months, though returned to the Teekon in search for a new life beyond the death place of her family.
