The Yuuzhan Vong were religious zealots, who viewed mechanical technology as blasphemy. A typical Yuuzhan Vong resembled a Human in form, though they were taller and heavier than the average Human and had less hair on their heads.
The Yuuzhan Vong and their Chazrach slaves were among the few alien species known to originate outside the galaxy (the only known others being the Silentium and the Abominor). The Yuuzhan Vong-” Children of Yun-Yuuzhan“, also called the Chosen Race, known to the Chiss and Ferroans as the Far Outsiders, and sometimes incorrectly abbreviated to Vong (which implied that one was disowned by their family and their gods)-were a sentient species that nearly destroyed the New Republic, and were responsible for the deaths of nearly 365 trillion sentient beings during their invasion of the galaxy.
