- "There haven't been any Yuuzhan Vong fleets in orbit since the original conquest, though sometimes Vong fleet elements, mostly coralskippers and their transports, transit the Ylesia system on their way to somewhere else. What we have instead is the Peace Brigade military itself."
- ―Kyp Durron
In 26 ABY, during the Yuuzhan Vong War between the New Republic and the Yuuzhan Vong species, the Yuuzhan Vong conquered the planet Ylesia. It was soon given to the Peace Brigade as their headquarters.
