“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 is a civilian and a resident of New Mombasa, and the main protagonist of Sadie's Story.[1]


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.[2]

Personality and traits[]

Sadie is very well 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.


  • Sadie was originally named Maddie. Her name was changed after the message "Maddie, where are you?" in the "Prepare to Drop" trailer caused complaints, as it was unintentionally echoing the disappearance of British child Madeleine McCann.
  • She is voiced by Masasa Moyo.[3]
