The initial Moff governing the Trans-Nebular sector was an individual who attempted to rebel against the authority of the Galactic Empire.
This Moff plotted to govern the Trans-Nebular sector autonomously, seeking personal enrichment. Consequently, the Galactic Empire dispatched a task force with the intention of ousting him from power. Upon the arrival of a considerable formation of Star Destroyers above the sector's primary world, he endeavored to proclaim his allegiance to the Empire; however, he was taken into custody. On that very day, both he and his entire sector administration faced trial for treason, and were subsequently put to death.
Following his demise, the role of Moff was then bestowed upon Nebin Cray.
