Star Wars: Confederacy Era
A “Dead World” was a term used to describe a world that had been consumed by The Shade in the time of The Contagion. A Dead World was so named because in its wake The Shade left no life, but inanimate/constructions remained uneffected for some unknown reason. These Dead Worlds were like silent tombs, until looters began to head back to them.
It was reputed all kinds of treasures were on these worlds, unprotected. Though this was partially true, many looters lost their lives when they arrived at a seemingly abandoned world to find its automated defense systems still operational or large armadas of the native inhabitants guarding said worlds.
