Aed Nneahrmem Highest Imperium
• Great Wars
1,780,765,323 PIE

The Empire of Aed Nneahrmem was a vast interstellar political power, which held control over a span of hundreds of light years, before its collapse in 565,578,734,253 PIE. Lasting nearly a billion years, the colossal edifice collapsed over the Twilight Period, a time-frame lasting hundreds of millions of years.


Technology and Economics

Aed Nneahrmem possessed sophisticated medical technology, extending the human lifespan to approximately 30,000,000 years; by eliminating both infectious and chronic disease, whilst nullifying certain portions of the human genetic code through epigenetics, the society reduced the chance of an individual's death to a constant of 23 billionths per year. The roughly simultaneous advent of antimatter-driven rocketry, combined with space-based systems which were essentially immortal (requiring virtually no maintenance for the duration of a trip), opened the door for extensive systems of interstellar trade and commerce. During the Empire, investors engaged in long-range economic activity extending for millions of years. An average ship had a capacity of 25 kilometers per second of velocity, and most took hundreds of thousands of years to reach other star systems.

A typical interstellar spacefaring vessel did not require active maintenance, as, following the initial acceleration phase, no onboard systems were running (thus, cruising vessels were essentially inoperative "meteors" during a journey). This was in stark contrast to planetary systems, like fusion power facilities and antimatter generators, that were actively running and thus required continual maintenance, needing human technicians and a supply of raw materials. Due to the vast time scale of investments, capital costs posed only a tiny percentage of overall infrastructure costs (aside from interstellar trade, which required large time scales), with maintenance and operations posing the majority of the cost. Drawing antimatter from parallel universes in accordance with advanced theoretical physics, antiproton production saw a cost of 10,000 Edai per kWh, mostly due to the costs of operating the antimatter facilities; this was the primary cost of running the antimatter-catalyzed fission-fusion drives, which required on average 2 micrograms of antimatter for an interstellar voyage.
