[Source] The Perkell sector was a sector located in the galaxy's Mid Rim that contained the planet Gromas. After the Carrion Spike, the personal corvette of Moff Wilhuff Tarkin, was stolen by a rebel cell and used to attack the Imperial space station Galidraan Station, a Imperial depot on Gromas was considered as one of only two potential refueling stations the corvette could visit. The corvette did not travel into the Perkell sector however, instead refueling at the planet Phindar in the Mandalore sector.
