Maal Lah was a Yuuzhan Vong Warrior of the male sex, and he was a crèche-brother to the Warmaster known as Tsavong Lah. During the conflict known as the Yuuzhan Vong War, he held the rank of Commander.
Belonging to the Warrior caste, Maal Lah was a male Yuuzhan Vong. As a member of Domain Lah and the crèche-brother of Tsavong Lah, who was a Warmaster, Maal Lah served as a Commander of one of the Yuuzhan Vong fleets deployed during the Battle of Coruscant. Although he typically preferred aggressive attacks, the strength of the opposing forces required him to moderate his tactics. Following the successful conquest, Maal Lah was escalated to the position of Supreme Commander, becoming one of Tsavong Lah's key tactical advisors during the Battles of Borleias. After he found out about the failure of Wyrpuuk Cha, Maal became convinced that Garm Bel Iblis was the mastermind behind the battle's coordination. Later, Maal Lah was dispatched to Ylesia, where he faced the challenging task of bringing the forces of the Peace Brigade under control. He was present during the New Republic's Raid on Ylesia, where his leg suffered irreparable damage. Despite the intense pain, he stated that the Shapers would provide him with a replacement leg, if the gods favored him. Tragically, he met his death when he was crushed by falling debris from a nearby structure.
