The Wraiths were an elite soldier squad in the extremist Mandalorian offshoot called the Death Watch. These Wraiths, who wore silver-white Mandalorian armor, operated from the Death Watch's hidden bunker situated on Endor's forest moon. Fenri Dalso, a Death Watch Wraith, was responsible for guarding the alum mines entrance at the base, while his comrade, Klin Nif, another Wraith, controlled entry to Section B of the Death Watch's bunker. In approximately 1 ABY, a number of Wraiths confronted several spacers attempting to infiltrate the base. During this intrusion, both Dalso and Nif were killed, and the spacers seized their pass keys to enter the areas they had previously controlled.
The Wraiths made their initial appearance in Star Wars canon within Star Wars Galaxies, the massively multiplayer online role-playing game, starting with the An Empire Divided update.
