Halo: Ghosts of Onyx begins in the year 2531 with a raid on an Insurrectionist base by the SPARTAN-II Blue Team. Their objective was to recover the stolen FERNIS nuclear warheads, but they were captured by rebel General Howard Graves; a former UNSC marine who defected to the insurrectionists. However, Spartan Kurt-051 manages to escape from the team before they are captured and helps the rest of the blue team escape capture by the insurrectionists. A month after the raid, the Blue Team is assigned to investigate a broken Shaw-Fujikawa Translight engine. Kurt is sent ahead to explore it, but as he gets closer to the engine, his equipment begins to malfunction. Eventually, the thruster he is using malfunctions and Kurt is sent spiraling into space with no communications. Kurt is then recovered by ONI and wakes up a month later to be briefed on the SPARTAN-III program by Vice Admiral Margaret Orlenda Parangosky, Rear Admiral Ned Rich, Captain Aaron G. Gibson, and Colonel James Ackerson aboard the Point of Never return of the UNSC. . Kurt is then promoted to lieutenant, junior rank and sent to Onyx to reduce 497 volunteers to 300 trainees. Kurt tests the candidates' desire for revenge against the alien behemoth that destroyed their homes and families by having them perform a midnight high-altitude jump from Pelican spacecraft. Any child who did not jump would have lost the ability to be a Spartan, and any child who jumped would have retained that ability. Even with advanced training and semi-powerful infiltration armor (SPI), all 300 Spartans would die in Operation: PROMETHEUS. Kurt returns to the Point of No Return to be informed of Alpha Company's success and to begin Beta Company's training. Kurt discovers that all of Alpha Company was wiped out during Operation: PROMETHEUS to... middle of paper... the Spartans. The Sangheili advance with Kig-Yar energy gauntlets while their brethren fire plasma rifles and needles overhead. They are eliminated by grenades, rocket launchers and rifles. The Sangheili attack again, but this time with Mgalekgolo's support. They manage to kill Holly-G003 and seriously hit Kurt. As the Covenant harass the Spartans, Kurt orders everyone to go through the Slipspace portal and enter the warehouse. Kurt stays behind to make sure Mendez, Halsey, and the Spartans make it safely through. Kurt sacrifices himself to deny the Covenant the Forerunner technologies by detonating two FERNIS nuclear warheads, causing a chain reaction within Onyx that results in the planet's destruction. Doctor Halsey, CPO Mendez, and the Blue and Saber teams are then trapped inside a Micro Dyson Sphere and attempt to find the Forerunner's stash of technology..
