Sla Tsun held membership within Domain Tsun and also held the title of one of six Yuuzhan Vong Supreme Commanders. He was in command of a flotilla dispatched to assault Zonama Sekot throughout the Battle of Yuuzhan'tar. He received orders from Warmaster Nas Choka, along with Supreme Commander Tivvik, to pilot their respective mataloks directly into Zonama Sekot. The question of Sla Tsun's survival following the battle remains unanswered.
