Lian Devereaux

"I can do everything you can. And more elegantly."

- Lian Devereaux to Vasily Beloi.

Sergeant Lian Devereaux is a UNSC Marine and an Orbital Drop Shock Trooper of the 10th Shock Troops Battalion. She is trained as a pilot. In January 2553, she was assigned to Kilo-Five, a highly covert intelligence unit under the command of Captain Serin Osman.

Post-war
In January 2553, she and two other ODSTs, Staff Sergeant Malcolm Geffen and Corporal Vasily Beloi, were hand-picked by the Office of Naval Intelligence to serve under Captain Serin Osman in a covert operations team known as Kilo-Five. They were tasked with sowing a war among the Sangheili to destabilize their homeworld. Devereaux was assigned as Kilo-Five's pilot, providing planetside transportation on the modified Pelican dropship she nicknamed "Tart-Cart", as they operated from the.

Devereaux went along with the rest of Kilo-Five as they traveled to New Llanelli for their first arms exchange with the Servants of the Abiding Truth. Devereaux stayed with the ship as Sangheili insurgent Avu Med 'Telcam was given tagged weapons and Tom Muir was extracted. Later she opened contact with Mike Spenser, who had been hiding on Reynes since the glassing of the planet and was going to be picked up next. During the extraction on Reynes, Devereaux became worried about Kig-Yar inspecting the Tart-Cart, but the team killed them after a quick fight. The team's next task was to save the who was damaged but near Venezia, a colony under Insurrectionist rule. However, the team witnessed the ship's destruction at the hands of Venezia.

Venezian movement
While Mal and Vaz infiltrated the Venezian militia, Naomi and Devereaux traveled to Anchor 10 with the Pelican Tart-Cart to retrieve a new dropship to Kilo-Five, having it immediately upgraded with the same capabilities as Tart-Cart by the Huragok Requires Adjustment. During the trip, however, Mal and Vaz were captured by the Insurrectionists on Venezia and Naomi and Devereaux were immediately tasked with the rescue mission. Devereaux piloted the Tart-Cart, while Naomi went after Mal with the Bogof.

Pious Inquisitor
Meanwhile, Kilo-Five managed to track down Pious Inquisitor, which had been boarded by a Kig-Yar pirate crew attempting to commandeer the ship for themselves. The mission was eventually a success and Kilo-Five was granted shore leave on Cascade. Devereaux went to a concert with Evan Phillips, the two having grown fond of one another during their time with Kilo-Five.

Trivia
Based on her accent, Malcolm Geffen surmised she was from northeast Canada. This combined with her surname suggests French-Canadian descent. Her appearance indicates Asian ancestry, further proven by Black-Box listening to her swear in Cantonese while working on the Tart-Cart.
