Fellow aliens?
While no people...
Of course, "Volnotov(i)ans" also include intergrated space vessels, plasma based life forms, sentient planets, stars and clouds of inter-stellar gas, beings of higher (4th) dimensions and those that can otherwise not be described using our limited human vocabulary.
That said, I tend to imagine the "original" "Volnotov(i)ans" (who were still arguably "Human") that arrived on the homeworld of Sedamodan to look somewhat Turkic and Central-Asian in appearance.
