Murgen was the Black Company's Standard-bearer and also spent some time as their Annalist. This was a very important title. Standard-bearers often became Lieutenants and even Captains. They were also responsible for guarding a powerful magic weapon, as in reality the Company standard was held by an ancient lance. Murgen also had the ability to leave his body and walk freely in spirit form.
He was first mentioned in The Books of the South, although he had served some time with the Company during their campaign in the North. He was described as a tall and quiet man. He was very introspective and spoke rarely. He had served for a while in The Lady's army before joining the Black Company after their rebellion against their employer. He was among the few survivors of the Battle of the Barrowland. At that time he was 28 years old and was the youngest among them.
The Battle of the Barrowland was the last military campaign of the Black Company in the Northern lands. Having lost the entire squad, Croaker decided to move South and seek their origins. Murgen joined him and started his training for an Annalist.
Their march to the South was prevented by the Shadowmasters and their armies. The Black Company was hired to defeat them and Murgen fought in several battles. At first the Company was winning. They defeated several of their armies and even managed to eliminate one of their leaders. At the Battle of Dejagore Murgen pierced the Shadowmaster Moonshadow with the lance holding the standard, thus ending the sorcerer's life.
The death of Moonshadow was not enough and due to unforeseen circumstances the Black Company lost the battle. Croaker was mortally wounded and Murgen tried in vain to assume command of the army. Their forces were split in two. Some of the Company survivors and Murgen retreated behind the city walls, while Lady and the others managed to retreat far away. The surviving soldiers in Dejagore were besieged by Shadowspinner for several months. The conditions were very harsh and the mortality rate was high. Mogaba, the highest ranking officer, was the official leader of the Company and the city. His ruthless methods, which involved executions and terror were supported by the Nar recruits from Gea-Xle. Murgen, who lead the veterans opposed his actions.
During the siege Murgen fell in love with Ky Sahra. She was a beautiful Nyueng Bao woman. She had green eyes, which was uncommon for her people. Murgen saved her family and she became his wife. After the siege ended, they went to Taglios with the rest of the Black Company. Croaker resigned as an Annalist and Murgen officially succeeded him. He was also given Croaker's room. About a week later the Stranglers attacked the palace with the intention to kill the Captain of the Black Company. Sahra was supposedly killed during the attack and Murgen was completely devastated.
Murgen and the Company continued their war with the Shadowmasters, now represented by their last remaining member – Longshadow. After a long campaign the sorcerer was defeated and captured by the Company at Overlook. Longsadow was protecting a gate to the Plain of Glittering Stone, which Croaker decided to explore. Murgen's standard allowed the group to enter the Plain, but their expedition was not successful. They fell into a trap, devised by Soulcatcher. Murgen and many of the Company's members were frozen in a stasis field and left beneath the Plain.
During his imprisonment he manifested his spirit walking ability again. He discovered his wife was actually alive. Sahra also felt his presence and realized he was imprisoned and in need of help. She and Sleepy led the remains of the Company against the armies of Soulcatcher and Mogaba for years, eventually freeing Murgen and the rest of the Captured. He was finally reunited with his wife Sahra and his son Tobo, but did not have much time to enjoy this reunion. He died during a failed attempt to capture Mogaba in the palace of Taglios.
