Elisabeth Bray

Doctor Elisabeth "Elsie" Bray was a member of House Bray. She worked for her family's corporation as a starship and weapons engineer, but disappeared in the years before the Collapse.

Biography
At the age of thirteen, Elsie built a Sparrow with the help of her adopted sister Ana for reasons she could not remember. This Sparrow would later become a production model, as the G-335 Anseris Overdrive.

Elsie designed at least two starships for Clovis Bray: the Eon Trespass and the Shadow Trespass. She completed work on the Eon Trespass three years before her disappearance, and attended the naming ceremony of the Shadow Trespass, which she designed with panels that helped it avoid detection by other ship's sensors.

Along with her sister Willa as well as Ana, Elsie worked at the BrayTech Futurescape in the Hellas Basin on Mars. Although she primarily worked in weapons research and development, she assisted other BrayTech scientists working on the Sn0-armor project. After discovering Ana was working on a prototype line of scout rifles, Elsie looked over her work and was pleased by the progress her sister was making. She returned the rifle to Ana and told her that only she could finish the design.

Elsie's work with weapons led her to to discover that the test nodes used for gauging weapon effectiveness in field conditions could be easily configured for use as a locking mechanism that could be easily hidden in many places. She would later make use of her discovery to protect a project of hers inspired by a friend researching the Vex on Venus with the Ishtar Collective, which made use of a Vex Core to simulate alternate timelines for the purpose using the information gained to alter the original timeline. This project developed into the Worldline Zero sword, which allowed Elsie to see visions of the future. The concept of the weapon itself also piqued the interest of Willa, much to the horror of Elsie, who was concerned about the potential dangers should others obtain it. Elsie wiped the traces of her research, and hid the sword in a storage cache within the Core Terminus locked using the test nodes. She disappeared three days later, after leaving a message apologizing to Ana and asking that the Worldline Zero be used to "make things right."

Rebirth as an Exo
In the Mysterious Logbook, it is revealed that Elsie had fatal prion insomnia. She inherited this disease from her father, Clovis Bray II, who had developed this condition as a result of the genetic modifications done to him by his father, Clovis Bray I

Although initially reluctant, Elsie eventually uploaded herself into an Exo body, both to save herself and to reduce the risk of her own corruption by the Vex. She subsequently came to the rescue of her grandfather when he was being tortured by a copy of Maya Sundaresh, who had subverted the elder Bray's automated surgeon during a multi-organ transplant.

Later, Elsie sent a message to her grandfather, in which she claimed to have constructed a paracausal weapon capable of utterly destroying the Vex around 2082 Volantis. Believing that this would compromise future Exo development and foreclose the future of humanity, Clovis I confronted his granddaughter and killed her in a fit of rage. However, he kept a backup of her initial upload scan, and reloaded her into a new exobody.
