Kha'ak Sector 926
This is the location of the shattered remains of the Kha'ak's homeworld, which was accidentally destroyed by the TF/CPU ships #efaa and #deff, when they made Black Hole Sun's star go nova. The star unleashed a gamma-ray burst, which hit the planet a few years later, and broke it. The Kha'ak's Hive Queen lives in orbit of this dead place.
Until the final mission of Operation Final Fury, the sector only has ships. Once that mission starts, there are two Kha'ak Stations, protected by Guardians. There's also a giant spherical cage that surrounds the sector.
Kha'ak Sector 926 does not have any asteroids, and the Kha'ak Homeworld's remains are not mineable either.
