Near the end of the Great Galactic War between the Sith Empire and the Galactic Republic, the Sith Lord Darth Azamin—a member of the Empire's ruling Dark Council—was assassinated by a strike team of Jedi. The operation was actually arranged by the Sith Lord Darth Decimus with the help of the Dark Councilor Vowrawn, and with his death Darth Azamin was replaced as head of the Sphere of Military Strategy by Decimus.
Darth Azamin was a member of the reconstituted Sith Empire's ruling Dark Council during the later years of the Great Galactic War with the Galactic Republic, and Azamin served as head of the Sphere of Military Strategy. However, Azamin's fellow Dark Councilor Vowrawn—a cunning political savant who had been on the Council since the beginning of the war—struck a deal with the Sith Lord Darth Decimus sometime before the end of the war in 3653 BBY In exchange for the elite Armageddon Battalion as his personal military force, Vowrawn arranged for the Jedi Order to learn the location of Azamin's personal stronghold and when the Dark Councilor would be weakest.
Taking the bait, the Jedi dispatched a strike team to Azamin's fortress, and the strike team managed to kill the Dark Councilor within the stronghold. However, the starship that the Jedi used to escape the fortress was sabotaged by Decimus and Vowrawn's agents, causing it to explode and kill the entire strike team.
In the wake of Azamin's death, Darth Decimus was elevated to the Dark Council with the support Vowrawn, and Decimus assumed Azamin's seat at the head of the Sphere of Military Strategy. In that position, Decimus carefully planned an Imperial invasion of the Republic planet of Corellia—a plan that he was put into action when war broke out after the decade of tenuous peace following the Great Galactic War.
Behind the scenes
The death of Darth Azamin was first described in the Codex entry for Darth Decimus in Star Wars: The Old Republic, a massively multiplayer online role-playing game released by LucasArts and BioWare. It was later expanded on in the game's 2012 reference guide Star Wars: The Old Republic Encyclopedia, which detailed Darth Vowrawn's role in the assassination and also identified Decimus—and thereby his predecessor Azamin—as the head of the Sphere of Military Strategy.
