The Kadok Regions, also known as Bitthævrian space, were the areas of space inhabited by the Bitthævrian race in the Wild Space, near Kalee and Huk. They never joined the Galactic Republic. The Tertiary Kadok system was in the Kadok Regions.
The Bitthævrians staged attacks against the local delegations of the Old Republic in Bitthævrian space. As Kalee was a nearby target, they also attacked that planet, leading to the Kaleesh–Bitthævrian War.
