The Kilji Illumine government's Illumine Kilhorde battle fleet long-range triad transmitter located on Colonal Station Chaf while they conquered several nations to the south and southeast of the Ascendancy to communicate with its leader, Generalirius Nakirre. Through the transmitter, Nakirre received reports of victory from his field commanders; however, one day the reports ceased, leading him to fear that his generals had foolishly extended their conquests to Colonial Station Chaf, which would have suspended the long-range triad transmitter's operation. In fact, however, the Kilhorde had been destroyed by the Paataatus Hiveborn government, which deemed the fleet's operations near their borders unacceptable and sent a Paataatus attack fleet to end them.
