James was recruited from his first position aboard a corvette after graduation at the top of his class in slip space and normal space navigation. Less than a year later the ship was heavily damaged in a minor engagement with the Covenant. After seeing that the corvette's repairs would take several months James took a position of the Prowler Dawns Shadow where he served until its destruction. The crew were able to evacuate the ship and regroup on the systems habitable planet.
They survived for a month avoiding covenant search parties from the planets outpost until a squad of ODSTs were sent in to take out the outpost and search for any surviving crew of the Dawns Shadow. At the end of the week long operation that ended with the disabling of the outposts communication systems. The group of survivors and ODST were picked up by a Pelcan dispatched from a Prowler waiting in orbit. There were only eight of the sixteen crew members who made it off the planet.
He was made the Captain of the Prowler Aurora's flame after taking command and holding the crew together. He did not fail to achieve a single objective since taking command although his ship has needed major repairs many times and he and the crew were almost lost in one of the final battles of the Covenant war. After the war he made many runs into covenant territory to either plant or retrieve ONI spies. After the discovering the Ark fragment Captain Terence was given command of both Aurora's flame and Guinie's smoke another Oni prowler to set up a research base on it.
