Imperial Interdicted Space was a region in the Elrood sector that surrounded the Derilyn and Berea systems, and stretched towards the Torina system. The area was granted its name after the planet Derilyn was placed under martial law by the Galactic Empire and the region was regularly patrolled by Imperial starships. Access to Imperial Interdicted Space was restricted and civilian vessels were permitted to pass through the region only if they had been granted a Derilyn Travel Waiver by the Imperial Navy.
