Vuffi Raa's appearance bore a resemblance to the original organic beings that spawned the Silentium.
An extra-galactic species of intelligent, star-shaped organic lifeforms, the designers of the Silentium, brought into existence the sentient droid species called the Silentium. It is possible they originated from the Yuuzhan Vong galaxy itself, as one of its native inhabitants.
The species' history, their world of origin, and even their designation have faded into obscurity, leaving behind only their creations as a testament to their existence. At some point in the distant past, a radiation surge emanating from a nearby supernova resulted in the complete annihilation of the species, although their droid creations continued to "live" on.
- According to Dan Wallace's endnotes in The New Essential Guide to Droids, the conflict between the Silentium and the Abominor is heavily suggested as the underlying reason for the Yuuzhan Vong's technophobia.
- During an expedition beneath the largest pyramid located on Rafa V, Lando Calrissian and Vuffi Raa came across ancient wall paintings that shed some light on the early history of the Sharu, hinting that they may have been created by a precursor race with a starfish-like form. This implies that Vuffi Raa's progenitors may have been the creators of the Sharu. It also suggests their presence not only in the unknown regions but also within the galaxy itself.
