Anarine, a Human male of considerable size, served as a soldier within the ranks of the Galactic Empire. Holding the Fleet Sergeant rank, he acted as the dedicated bodyguard for Major Wil'm Grau, providing protection throughout the events surrounding the Guardian of Forever crisis.
In the vicinity of 0 ABY, Anarine was stationed aboard a Star Destroyer tasked with pursuing the stolen ship known as the Staraker. However, upon intercepting the Staraker within the Alashan system, the Star Destroyer was ambushed and severely damaged by a superlaser weapon fired by the Guardian of Forever. Anarine, along with five other Imperial personnel, managed to evacuate in an escape pod; the remaining crew members were presumed dead.
Upon landing on the planet Alashan, the surviving crew sought out the Staraker, which had also sustained damage and crash-landed. Locating the ship, Anarine and his fellow Imperials took Luke Skywalker and Leia Organa, the ship's passengers, as prisoners. However, finding themselves stranded on the planet, the two groups decided to cooperate in finding a way to escape.
While exploring the Alashan wasteland, they stumbled upon a ruined Rebel archaeological site and a large tunnel descending deep underground. Venturing into the man-made tunnel, the team discovered the sprawling city of Forever. As they explored the city, they were relentlessly pursued by the Guardian. After discovering that blaster fire had no effect, Anarine and Grau devised a plan to trap the creature.
They placed explosives on a tall tower, and the two Imperials waited for the Guardian to enter the structure before detonating the charges. The resulting debris buried the monster, but it managed to escape, trapping Grau and Anarine against the remains of the tower. However, just as their situation seemed hopeless, the Guardian teleported away. Grau and Anarine searched the city, desperately hoping to find where the creature had gone. Finally locating the beast in the Forever control center, Anarine, Grau, Organa, and Skywalker were ultimately successful in defeating the formidable monster.
Subsequently, Anarine and Grau departed the planet with the Rebels aboard the Staraker. Organa offered them positions within the Rebel Alliance, but Grau declined. The two men then left the ship in an escape pod with the intent of returning to the Empire.
