Sadie Endesha

"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.

Sadie Endesha was a civilian and a resident of New Mombasa.

Biography
Sadie was born around the year 2533. Her mother, who was a passionate public defender, was killed by one of her clients when Sadie was still young. This prompted her father, Dr. 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 and upon discovering that Vergil was now infused into the Huragok, Quick to Adjust, ONI decided to let her become Vergil's handler. At some point in 2555, she was captured by United Rebel Front forces from Talitsa to lure Vergil into enemy hands before they were rescued by the remnants of Alpha-Nine.

Personality and traits
Sadie is a dedicated citizen, attempting to enlist in the UNSC defense force despite the high fatality rate. She is shown to be caring, mourning Tom Uberti even though he gave her and Mike away, nearly resulting in her death.
