Prior to August 26, 2549, this engineer sent a proposal for Project MAGNES, along with the schematics for the Grappleshot, to the United Nations Space Command. She hoped it could be adopted by the UNSC and integrated into the MJOLNIR Powered Assault Armor employed by Spartans, but the proposal was rejected by the UNSC.
On August 26, 2549, the engineer built a prototype in her own lab, and begun conducting her own tests, recording each conductive transfer test with the intent to submit the logs to the UNSC for approving the project. Over the next several weeks, she conducted tests on the prototype, refining the device with each failure. She maintained a good relationship with her daughter, who she communicated with over video call.
On September 14, 2549, the prototype operated successfully during the seventy-eighth test, rapidly pulling the engineer across her lab to the wall she had fired at. The engineer was initially wincing from the impact, but she quickly broke down in joyful tears when she realized the prototype worked.
Project MAGNES would lead to the creation of the Grappleshot, which was adopted by the UNSC and implemented to the MJOLNIR Powered Assault Armor [GEN3] by May 2560. The Grappleshot would allow Spartans to acquire objects that were out of reach, or attach the grappling hook to a surface for rapid movement on the battlefield.
The engineer was portrayed by Belgian actress Lubna Azabal.
