The United Earth Directorate Defense Corridor Alpha, otherwise known as the UED Koprulu Corridor, is a UED controlled corridor. It was established after UED Admiral Borealis Norsoutha, commander of the UED expeditionary fleet, established a corridor in the Koprulu Sector, an act that would give the UED a place. It is composed of Abaddon, the Tarsonis system, The Baker's Dozen, and Zenn. It is currently under the sovereign authority of the United Earth Directorate and guarded by UED expeditionary forces.
