Cailean-378

Cailean-378, formerly known as Cailean Macchruim, was a SPARTAN-II Class II supersoldier assigned to Aureolin Team, led by Javier-152. Requisitioned by the Office of Naval Intelligence immediately after augmentations, Cailean and Aureolin were deployed on top-tier black operations, including activities such as putting down rebel groups, tracking and eliminating Covenant Special Forces teams, and even neutralizing rogue ONI cells. During the, they defended ONI assets and evacuated key personnel to ONI prowlers in orbit meant to transport them to a secret location. During the evacuations, Cailean was forced to leave hundreds of civilians behind to save several dropships containing ONI personnel. This event weighed heavily on his conscience, and even after the war he felt guilt for his actions, which was eroding his faith in ONI and the UNSC. In 2557, it boiled over, after bad intelligence on a mission to destroy a rebel supply depot led to the destruction of a camp for the families of the rebels, and the deaths of dozens of innocent men, women, and children. This caused Cailean to fake his death during the evacuation, escaping to a nearby space port, where he stole a small freighter and escaped the planet. After managing to remove the UNSC neural interface, he became switched between several odd jobs, including being a mercenary, a Black Market supplier, a security guard, and even an agent of the dreaded Syndicate for a short while. Eventually he found a job arming civilian freighters with small auto-cannons to protect against pirate raids, and it was during this time period that he first encountered the freelancer freighter captain Gavin Dunn.
