 This leads to the sectors in between to be grouped together in (generally) sets of three, termed 'octants', as three sectors are one eighth of the rim of the galaxy, and which are sometimes inaccurately referred to as 'sectors' themselves.The Storm Zone is unoccupied, as even bases cannot exist there due to the severity of the storms, and ships cannot penetrate the Radiation Zone.The Core of the galaxy has never been explored.
