Lieutenant Bethany Durruno was a UNSC officer who served on the senior staff of the prowler UNSC Dusk in the 2550s. In 2552, she was at her post during the Battle of Earth and, under the command of Commander Richard Lash, navigated the ship to Installation 05, following the UNSC In Amber Clad who followed Solemn Penance, the CAS-class assault carrier of the High Prophet of Regret. She then navigated the ship back to Earth, to Onyx, and back home after the Battle of Onyx.
She was extremely fatigued, the constant action the Dusk had seen had taken its toll on Durruno, as it had the entire crew. She called time upon her UNSC naval career shortly afterwards.
