Shepard sector
The Shepard sector was a spatial region that was located in the Alpha or Beta Quadrant. In the 23rd century, it was considered Klingon territory.
On stardate 4326.3, Korrd was assigned the task of commanding Klingon patrol forces in this sector. During his command, Orion merchant raiders overran Klingon outposts, in what became known as the Feira incident. The Klingon High Command held Korrd responsible, and he was eventually exiled to a diplomatic position on Nimbus III. (Star Trek V: The Final Frontier, okudagram)
