Belderone and Kulthis both had Stenax colonies. The reason the Stenaxes colonized these planets is unknown. They remained isolated from the other inhabitants, on Belderone settling a previously uninhabited continent. Thankfully, they did not participate in the Stenax Massacres. After the defeat of Waru and the destruction of the star Crseih, the New Republic sought to relocate the homeless Firrerreos, whose homeworld had been desolated by the Galactic Empire. The Firrerreos had been placed in suspended animation in slaveship by the Empire. Flint persuaded the Belderonians to accept the Firrerreos on Belderone. However, rivalry between the two peoples arose. The Yuuzhan Vong used this rivalry to their own ends, setting the Firrerreo and Belderonians against each other. Belderone, weakened by internal conflict, was then easily conquered by the Yuuzhan Vong, who enslaved the Belderonians and rendered the Firrerreo all but extinct.
