- “You can't just give up — throw away your life!”— Sadie to Jonas, after realizing he isn't trying to get out of the city.
- Main article: Sadie's Story
Sadie was born in the year 2533. Her mother died at a young age, which prompted her father, Daniel Endesha, to write a sub-program called "Vergil" into New Mombasa's urban infrastructure AI, the Superintendent, to watch over and protect her. She was clearly irritated by Vergil's "over-protective urges," but she also adored him; she was reduced to tears when she was forced to leave Vergil behind to evacuate New Mombasa, telling Vergil that he was all she had left of her recently deceased father. She and Mike Branley traversed the war-torn New Mombasa during the Covenant invasion of Earth. They managed to escape alive with the help of Vergil. During this trip, she and Mike grew closer together, which hints that a relationship may have formed between them after they escaped the city.
After the war ONI decided to let her be the handler of Quick to Adjust, the Huragok that had combined with Vergil. Sometime during 2555, she was captured by the United Rebel Front in order to lure Vergil into their hands. She was later rescued by Alpha-Nine.
Personality and traitsEdit
