Mogaba was a very tall and well-built man with dark skin. He and his 32 warriors joined the Black Company in Gea-Xle. He and his group were actually descendants of the Black Company’s brothers. They were living according the Company's traditions. Mogaba was the strongest and most skilled of them all. Each of his men had defeated a hundred others in order to join the march to Khatovar, which was a religious act in their eyes.
Croaker was impressed by him and described him as the best soldier he had ever seen. He became the commander of the infantry and was given one of the Black Company's legions. During the Battle of Dejagore he and his men retreated to the city and held it for months. Shadowspinner sieged him and even flooded the city. Famine and diseases were plaguing the population and Mogaba had to execute many. One of his men revealed that Mogaba was actually of the cult of Kina and was drinking the blood of his victims and eating their flesh. He had planned to become the Captain of the Black Company and follow their original and sinister mission
Once Shadowspinner was defeated Croaker entered the city to negotiate with Mogaba. He handed over the city peacefully. He even asked for a merciful death as there was a shadow implanted in him. Croaker chose to spare his life, as he sensed there was still something good left in there.
Unfortunately for the Company, Mogaba fled to the south and, seeing no other option for himself, joined with Longshadow. With the other Shadowmasters all dead, Mogaba was appointed as commander of the remaining armies of the Shadowlands. Despite their significant defeats in the north, Mogaba raised enough soldiers that he was confident in his ability to defeat Croaker and the army of Taglios in open battle. When Longshadow fell and was captured by the Company, Mogaba's allegiance again transferred, this time to Soulcatcher in her new role as Protector of all Taglios.
In Taglios, Mogaba managed an ambush using the remainder of Soulcatcher's shadows that decimated an assassination team sent to remove him, which slew the Howler. His defense of the city killed many of the Black Company's best soldiers, including the Captain, Sleepy. Eventually, Mogaba fled the city with the other high officers who had helped rule Taglios under the Protector. However, their ship was accosted by the Unknown Shadows under Tobo's control, and Mogaba finally met his grim end.
