The Silentium's creators were an extra-galactic species of sentient star-shaped organics who created the sentient droid species known as the Silentium. They were possibly one of the native species of the Yuuzhan Vong galaxy.
Their name, homeworld and history have been long lost, with their creations being their only legacy. At an unknown time, the species was wiped out by a radiation storm from a nearby supernova, though their droid creations "lived" on.
- The war between the Silentium and the Abominor is strongly implied to be the root cause of the technophobia of the Yuuzhan Vong, according to Dan Wallace's endnotes for The New Essential Guide to Droids.
- While traveling underneath the largest pyramid on Rafa V, Lando Calrissian and Vuffi Raa saw historic wall pictorials which indicated a little of the ancient history of the Sharu, and suggested they were created by a starfish-shaped precursor race. Thus there is implication that Vuffi Raa's progenitors may have been the makers of the Sharu. This also indicates that they were not only present in the unknown regions but as well in the galaxy.
