- Early colonization: First colony ships launched from Earth. The colony fleet that would eventually land in the Nashtari star cluster is one of several sponsored by the United States and former British Commonwealth powers. Former Eastern Bloc nations and several influential Asian countries launch their own colonial expeditions at roughly the same time. Planet Luminaire in the Beta Aquilae system colonized by North American and Eastern Asian settlers.
- Discovery of the drug called Valkyr on one of the earliest colonies, one of the few to arrive at their destination before the invention of the FTL drives. Causes the unlocking of previously unknown human potential but at a significant physical and psychological cost
- Worldwide Hegemony: Well after the departure of the colony ships, but while the fleets are still en route, the beginnings of the Empire begin to emerge. The catalyst for the formation of the Empire is the invention of a practical FTL drive by an ideologue scientist named Victor Prokofiev; Prokofiev envisions a grand destiny for the human race among the stars, one far beyond the scope of the original colonial expeditions. A coalition of nations join together to better exploit this new technology and carry humanity across the galaxy; they begin to fall under the sway of corruption and internal infighting on matters unrelated to their star-spanning ambitions.
- Empire Established: Military leaders stage a coup using the warships developed to conquer the cosmos; the Empire is born. Imperial vessels move out to colonize inhabitable worlds, starting with the ones targeted by the earlier colony ships. In many cases, the FTL-equipped Imperial ships arrive at their destinations before the massively slower colony fleets.

Empire ultimately victorious but many colonists escape into the void with their own FTL equipped ships. Konige civilization founded, and frequently wages war with the Empire. Empire always victorious, but Konige never destroyed due to factions within the Empire wanting to preserve and study the Awesome. The Konige also make good boogeymen for maintaining military control.
