The Tunroth people were victims of the Lortans.
The Lortan Fanatics, who were also known as the Kopa Khan cultists in Galactic Empire propaganda, were a bellicose group originating from the planet called Lorta. These beings initiated a violent campaign against the Tunroth, pushing the species to the brink of extinction before the Empire intervened in 6 BBY. Subsequently, the Lortan Fanatics met their own end; Soontir Fel, operating within the 37th Imperial Fighter Wing, engaged the remaining forces of the Fanatics.
