At time plus two minutes (to use human time measurements), Ghad-auf-Getag, Supreme Commander of Nidu Military and uncle to the previously presumptive but now merely potential heir to the throne Hubu-auf-Getag, found his head being yanked backward to expose his throat. For the two minutes previous, Ghad-auf-Getag had sole administrative control of the Nidu military, without oversight from the Nidu Fehen—because there was none. Ghad-auf-Getag had not used those two minutes particularly well; for their entire span he been squatting above a Nidu toilet trough, expelling the remains of the previous day's lunch.
This left him particularly vulnerable to attack when his two bodyguards entered his lavatory and drew their knives—ceremonial knives Ghad-auf-Getag had presented both a year previously as a token often Nidu years (roughly fifteen Earth years) of loyal and devoted service. Both bodyguards had been promised colonial regional governorships by Narf-win-Getag; both had decided that Narf-win-Getag's offer beat a nice knife. One of those knives was stuck in Ghad-auf-Getag's throat; a few seconds later the second cut him from waist to mid-chest.
Ghad-auf-Getag's bodyguards were brutally efficient in dispatching their master; by t-plus three minutes and thirty seconds all of Ghad-auf-Getag's brain activity had ceased, triggering the implant he like all high-level government officials carried in his body to transmit the fact of his death to the Nidu computer network.
With the death of Ghad-auf-Getag, the administrative powers he controlled were instantaneously and automatically portioned off to his immediate subordinates, the chiefs of staff of the respective arms of the Nidu military—except for the control of Nidu's Glar-classs destroyers, which Ghad-auf-Getag and the previous Fehen Wej-auf-Getag believed was too important to be left to a mere chief of staff. Ghad-auf-Getag kept control of the Glar destroyers himself and cut them out of the chain of command. And so, when he collapsed to the tiles of his lavatory, bled out, control of the Glar destroyers devolved directly to their individual commanders.
Six of whom Narf-win-Getag had been able to buy.
At t-plus five minutes—and in a truly remarkable bit of synchronization—both the the Lud-Cho-Getag and the Jubb-Gah-Getag, the two Glar destroyers UNE Defense had been tracking from the start, emerged in Earth space in an unauthorized and unscheduled appearance and immediately warmed up their weapons. UNE Defense commanders had been briefed on the possibility of the appearance of the two cruisers and the further possibility—probability—that they would not be stopping by for a friendly spot of tea. What they were not told to expect was that the two ships would appear in Earth space within thirty seconds of each other, a bit of coordination that was an unheard-of feat of planning and power distribution to n-space engines, considering that the ships had come from entirely different limbs of known space, and were known to have entered n-space at nearly exactly the same time. The appearance of both simultaneously gave Earth defense planners no time to counter.
Bob Pope was awakened from a dead sleep by his new temporary assistant Thomas Gervis; he in turn woke up President Webster. Webster held off attacking the destroyers, partly to keep from losing UNE Defense ships unnecessarily but also because until he heard otherwise Nidu was still an ally. The unbidden and unscheduled arrival of the destroyers was not enough to breach treaties. If the UNE moved to attack it would be the aggressor and the breaker of treaties. There was nothing to do but wait.
The commanders of the Lud and the Jubb were both bought off years before with their choice of planetary colony governorships. The captain of the Lud picked Hynn, one of the newer colonies, rich in natural resources and anecdotally believed to be the home of some of the most attractive Nidu females in the entire nation; a perennially popular Nidu folk tune that expressed a belief to that effect had a close cousin in Earth's equally perennially popular folk tune "California Girls." The captain of the Jubb had lost two dearly beloved siblings in the uprisings on Chagfun; he chose that colony to rule and was already constructing intricate revenge fantasies against its entire population.
Narf-win-Getag had had no problem convincing Ghad-auf-Getag and Hubu-auf-Getag to dispatch the Lud and the Jubb to Earth space; the two had already been convinced by the apparent assassination of Lars-win-Getag that the Earth government was acting against their (and therefore Nidu's) best interests and the further unfolding of events suggested it would have to be dealt with as soon as possible after the coronation ceremony. What had been far more difficult had been to convince the two to do what was coming up next.
At t-plus 12 minutes four Glar destroyers (with two future colonial governors, one future Supreme Commander of Nidu Military, and one future very, very rich retired captain among them) popped into existence over Nidu itself, joining the two Glar destroyers already on station in Nidu orbit. All four arrived within 20 seconds of each other—a feat one order of magnitude more impressive than the synchronized arrival at Earth—two each in positions flanking the two Glar cruisers already in orbit.
This had been Narf-win-Getag's improvisational masterstroke, and like many masterful improvisations, it was based on years of backstory. Narf-win-Getag knew that two of the Glar captains could not be purchased—they were nephews of Ghad-auf-Getag and cousins of Hubu-auf-Getag. Rather than buy them, he bought those around them, not to assassinate the cousins but to implicate them in a deep and subtle conspiracy against Hubu-auf-Getag that would come to light at a time of Narf-win-Getag's choosing.
At the appropriate moment (which eventually turned out to be just after the UNE began the search that would turn up Robin Baker) a trusted and apparently unimpeachable third party—who, in a refreshing change of pace for Narf-win-Getag was not bought but blackmailed—would come forward and present evidence that the cousins meant to prevent the coronation and use their destroyers to force a coup. This third party would then suggest recalling the four remaining Glar cruisers as a preventative measure.
The third party: Chaa-auf-Getag, brother of Ghad-auf-Getag, uncle to Hubu-auf-Getag, and father to the Glar destroyer captains in question. Who really ought to have known that a fetish for xenosexuality—the desire to have sex with sentient races not your own—would one day catch up with him in a culture as caste-ridden and implicitly racist and xenophobic as the Nidu.
No matter how shamed Chaa-auf-Getag would be if his alien-fucking ways were discovered, there would be no way he'd countenance the actual murder of his own children. Which is why Narf-win-Getag never bothered to explain to him what would happen at t-plus 15 minutes, when the four destroyers opened fire on the destroyers captained by his sons.
The two destroyers were of course entirely unprepared for the attack—and yet survived the first barrage, heavily damaged but largely intact, a testament to their Hamgp makers' superior shipbuilding skills. But even advanced Hamgp craftsmanship couldn't survive the impact of a Nidu planet cracker bomb, one of which hit each of the stricken destroyers as the sole weapons in a second wave of attack. The destroyers each disintegrated in the wake of a shaped blast designed to rip into the skin of a living world, leaving nothing but metallic vapor and a pair of explosive jets expanding conically away from the planet of Nidu.
It would have killed Chaa-auf-Getag to know he had been used to condemn his sons to death. So it was just as well that at t-plus six minutes, Chaa-auf-Getag's trusted personal servant of nearly two decades stuck a large-gauge shotgun into Chaa-auf-Getag's exceptionally surprised face and calmly pulled the trigger. This was another instance where Narf-win-Getag didn't have to make a payout or promise; the personal servant, a Nidu of extreme conservative personal inclinations, saw it as an opportunity to express his opinion about Chaa-auf-Getag's need to stick his penile array into places, people, and species it ought not have been. Having expressed the opinion, the personal servant then turned the shotgun on himself; his personal inclinations being conservative as they were, it was the only option that would suffice for a disloyal servant.
