The Silentium's creators were an extra-galactic species of sentient star-shaped organics who created the sentient droid species known as the Silentium to resemble their form, in much the same way that humanoid sentients created bipedal droids. Their name, homeworld and history have been long lost, with their creations being their only legacy. The species were known to have been advanced. At an unknown time, the species was wiped out by a radiation storm from a nearby supernova, though their droid creations "lived" on.
