Aside from this, the only other legacy left behind by the Klikiss race is the large number of Klikiss robots (apparently designed in their likeness) that were reactivated half a millennia ago by the Ildirans.
A number of Klikiss evidently survived the genocide, as they reappear (in droves) on the planet Llaro at the end of Of Fire and Night, ready to take revenge on their traitorous robots and reclaim their old worlds, now colonized by the Hansa.
