Abigayle Singh

Abigayle "Abbie" Singh was one of the last surviving members of the Free States.

Background
Abigayle Singh was a member of the Free States, the last surviving member when the Vault Dweller discovers her bunker. She entered her bunker at a young age along with her father Niraj, brother Calvin, dog Dax, along with three members of the Cohen family, including Daniel Cohen. Her mother, Geneva, was already deceased before they entered the bunker. They all would ride out the Great War in this bunker.

Many of her terminal entries located in the bunker described the difficult living conditions stuck in the bunker, especially on her mental health.

When the surface was hospitable enough, Abbie and her family left the bunker in 2079 and began to explore Appalachia along with the other members of the Free States, although they mainly stayed around the Mire region. At some point, Dax disappeared, and Abbie figured the dog was dead and blamed it on Calvin.

Her father heard a message from Raleigh Clay about survivors attempting to rebuild life at Harpers Ferry, which the Singhs and Cohens agreed to. She worked briefly with Ella Ames in the clinic at Harpers Ferry, but resigned due to social difficulties dealing with the Responders. Ella was also studying deathclaw feces due to their radiation properties and named their droppings "bone meal." With the help of Abbie, Ella was able to develop a tracker to help her find the bone meal. A paper note indicates that she was known and respected by JD Sunday and Jesus Sunday. She also knew R. Fields and expressed to them about considering going south to Watoga. Unfortunately, in 2086, Harpers Ferry was attacked by a massive Scorched outbreak and their work on rebuilding the town was lost.

To combat the Scorched, her father began to work on a system called the Scorched Detection System (SDS) which her father instructed her on once she was old enough and in case of his death. Suffering from Parkinson's, he eventually died, along with Calvin. The Cohens were killed by the Scorched.

Being one of the last surviving members of the Free States, and the only person that knew the SDS inside and out, Abbie set up a series of recordings for any survivors to finish what the Free States started. She noted that at some point, she was certain everyone that she knew was dead; she regretted all her time working on the SDS, feeling that life would have been better if everyone simply stayed in their bunkers, as it meant they would at least be alive and she would not have to deal with her crushing loneliness. She was unable to finish her work on the SDS, so she packed up a bag and went to the Top of the World to find Hank Madigan's uplink.

The Vault 76 residents pick up where she left off with the Early Warnings quest.
