The Crucible

Finally, Nitro commenced his attack on the Confederacy. To the surprise of his enemies, he unveiled the HK-101 a so-called 'successor' to HK-51. Nitro had also founded House Abyssus and sired two children with his wife Styxia: Arkana and Korvo. Systematic warfare occurred throughout the galaxy, with a thousand worlds drowned in the blood of soldiers on both sides. To the surprise of Orono and his House, Arkana and Korvo entered Dras Edoc'sil eager to defect. Orono sensed the truth in their words, as neither had the dark taint of Nitro's doctrine. They struck a deal; if they helped kill their parents and end the war before it shattered the galaxy, they would be welcomed as an ally of the Zoiji Confederacy. Many years later their parents were defeated. Styxia was slain by her own daughter, slashed through the skull. Nitro, after a lengthy battle only his children and House Zoiji working together could win; reverted to the corpse he truly was. Their bodies were devoured by corpses of the vengeful fallen summoned by Koschei and the power of countless souls bequeathed to their children. They were even given a choice of a bride and groom from the Zoiji family, and a royal name all their own, bought in the blood of patricide...
