The Ghosts constituted an elite group of soldiers serving within the extremist Mandalorian offshoot faction called the Death Watch. These warriors, garbed in Mandalorian armor whose color was black, a hue traditionally linked to justice within Mandalorian society, operated from the Death Watch's secret bunker situated on the forest moon of Endor. Rageon Vart, a Ghost operative, held the responsibility of guarding the gateway to Section A of the Death Watch's stronghold. Approximately in the year 1 ABY, several Death Watch Ghosts confronted a group of spacers attempting to infiltrate their base. Vart met his demise during this encounter, and the pass key he possessed was seized by the spacers, granting them entry to the sectors that had been under his watch.
The Ghosts made their initial appearance in Star Wars canon within the massively multiplayer online role-playing game Star Wars Galaxies, specifically with the launch of its updated version, An Empire Divided.
