The Gg (pronounced /gek/? or "Geg") were known only by the now-extinct Burvixese, who communicated with the Gg via long-range HyperWave broadcasts. It was the Gg who warned the Burvixese of the approach of the hostile Kohr-Ah, as well as the accurate conjecture that the Kohr-Ah used HyperWave transmissions to locate their prey.

Since the Gg were loath to engage in visual transmissions, their appearance is likely to remain an eternal mystery, as their world was incinerated by the Kohr-Ah in 2142 with no known survivors.
