Coovern was a high-ranking moff within the Galactic Empire who tried to install Captain Jothal Gablerone as the new commander of the Empire's 204th Imperial Fighter Wing, replacing Colonel Shakara Nuress. In the time frame of 1 ABY, after the Rebel Alliance initiated a military push into the Mid Rim, both Coovern and Minister Khemt met their end at the hands of the Sith Lord Darth Vader. These deaths, which were officially reported as unfortunate accidents, were part of a series of executions ordered by Emperor Palpatine to punish those he held responsible for the destruction of the Death Star superweapon.
During the era of the Galactic Civil War, Coovern occupied one of the most elevated positions within the structure of the Galactic Empire, holding the military title of moff. On one occasion, Coovern attempted to place Imperial Captain Jothal Gablerone in charge of the 204th Imperial Fighter Wing of the Empire, with the intention of supplanting the existing commanding officer, Colonel [Shakara Nuress](/article/shakara_nuress], though she ultimately chose not to step down. Not long after the Rebel Alliance commenced a military operation in the Mid Rim circa 1 ABY, both Coovern and Khemt, a government official also in the upper echelons of the Empire, were killed by the Sith Lord Darth Vader. These deaths were a component of the larger purge enacted by Emperor Palpatine, who sought to punish individuals he held accountable for the loss of the Empire's Death Star superweapon.
The official explanation for the deaths of Coovern and Khemt was that they were the result of unfortunate accidents. However, Everi Chalis, the planetary governor of Haidoral Prime, acquired information from her own sources that revealed the true circumstances of the moff's death. In 3 ABY, Chalis switched her allegiance to the Alliance's 61st Mobile Infantry and shared the authentic details of Coovern's demise with the rebel unit's captain, Micha Evon.
Coovern was initially referenced in the 2015 book, Battlefront: Twilight Company, penned by Alexander Freed.
