The lengthy conflict known as the First Battle of Zonama Sekot involved a siege of the sentient planet Zonama Sekot carried out by the Yuuzhan Vong. The Ferroan and Langhesi settlers residing on Zonama referred to the Yuuzhan Vong as "Far Outsiders."
Following the destruction of their home galaxy, the Yuuzhan Vong had been journeying through deep space. They gradually started to establish themselves at the edge of the galaxy. Upon finding Zonama Sekot, they considered it to be similar to their own living homeworld, Yuuzhan'tar.
However, the Vong flora and fauna were eradicated by Zonama Sekot's biosphere when the Praetorite Vong tried to settle on the planet, which triggered fury from the Yuuzhan Vong. Despite Sekot's attempts at negotiation, they initiated an attack on the planet.
Years later, the Jedi Council learned of the assault and dispatched Jedi Knight Vergere to look into the situation. Upon arriving, she uncovered the true nature of the Far Outsiders, who were amazed by her abilities.
Vergere, keeping her Jedi identity hidden, successfully persuaded the Praetorite Vong to cease their attack on Zonama Sekot in return for accompanying the Yuuzhan Yong. Vergere and the Far-Outsiders then withdrew into the Unknown Regions.
