Kenneth Donnelly: Normandy Engineer

Kenneth Donnelly was a human engineer from Scotland who served in the Systems Alliance and later aboard the frigate Normandy SR-2. A skilled but headstrong technician, he ran the engine room alongside his closest friend, Gabriella Daniels, and crossed from Alliance service into the ranks of Cerberus and back again over the course of the war against the Reapers.

An engineer of the Alliance#

Donnelly graduated from a technical academy in the same class as Gabriella Daniels, and the two served together aboard the Systems Alliance vessel SSV Perugia at the Battle of the Citadel. In the aftermath, when the Alliance moved to discredit the existence of the Reapers, Donnelly openly voiced his support for the warnings given by Commander Shepard, an outspokenness that came close to insubordination. He escaped court martial only because his skill as an engineer made him too valuable to lose, and that same combination of talent and candor brought him to the attention of the Illusive Man.

Service aboard the Normandy SR-2#

Donnelly was recruited into the Cerberus crew assembled to investigate and stop the Collectors, taking up a post in the engine room of the rebuilt Normandy SR-2. Daniels arranged to be included in the same contract, certain that he would struggle without her, and the two worked side by side managing the ship's drive systems. Unlike many of the Cerberus personnel aboard, both seemed almost wholly unaware of the organization's more ruthless activities, and Donnelly said plainly that he had joined for the chance to strike back at the Collectors rather than out of any allegiance to its cause.

When the Collectors boarded and seized the Normandy, Donnelly was among the crew taken captive, and whether he survived the ordeal depended on how quickly Shepard turned to their rescue. Provided he lived, he was detained along with the rest of the crew when the Alliance later impounded the ship.

The war against the Reapers#

With the Reapers' invasion underway, Donnelly could be cleared to return to work in the Normandy's engine room through Shepard's authority. Chief Engineer Adams regarded him as gifted and dedicated, if frustrating in his disregard for the chain of command, and was glad to have him back on the team all the same. He and Daniels, if she too had survived, resumed their old duties on the engineering deck through the final campaign. His fate beyond the war, like much of the conflict's outcome, turned on the decisions Shepard made in its closing days.
