The warmaster was the leader of the Yuuzhan Vong army and fleet.
The warmaster was often addressed as the Fearsome One. All warmasters were remade in the image of Yun-Yammka, the god of war. The warmasters were second only to the Supreme Overlord.
The first warmaster was a vua'sa created by Yun-Yuuzhan instead of a Yuuzhan Vong. A Yuuzhan Vong warrior challenged and killed the beast, and thus the title was carried on by Yuuzhan Vong warriors.
At the time of the invasion of the galaxy, the warmaster of the Yuuzhan Vong was Tsavong Lah. His father, Czulkang Lah, had been warmaster before him. Most warmasters were killed in battle, but Tsavong Lah wrested the title from his father by right of combat, sparing the elder warrior's life out of familial attachment. Czulkang Lah went on to become one of the most respected teachers of warriors until falling in battle in 27 ABY.
When Tsavong Lah was killed by Jedi Knight Jaina Solo on Ebaq 9, Supreme Commander Nas Choka was escalated as the next and final warmaster of the Yuuzhan Vong. He led his forces into battle against the Galactic Alliance in the decisive Battle of Yuuzhan'tar, though ultimately surrendered to the enemy after the truce on Zonama Sekot.
