Welcome back! In today's content showcase I will be talking about what is going on in the chronologically first 2 scenarios present in Solar Nations. Unfortunately, that means no mechanical discussions so if that isn't your cup of tea I'll see you next week!
The first thing you'll notice is that there is much more 'neutral' space at this point in time, that is because the hyperdrive has only recently been introduced to the Galaxy, so larger and more centralized states are much rarer. Furthermore, population numbers are by far the lowest of any scenario, making this scenario ideal for those who want a more 4x like experience.
Built on what was originally an ordinary planetary confederation centered around the prosperous world of Cenna, the Lativerian Empire is at the height of it's power, having made use of the military innovativeness of it's Emperor to revolutionize interstellar war. While powerful, the Empire's wellbeing is increasingly reliant on that of it's Emperor, as his cult of personality degrades the institutions on which the former confederation was built. Furthermore, the Empire's explosive growth has created a huge administrative burden that, with time, will likely destroy the Empire if no action is taken.
The Solaire Worlds, due to the circumstances of their colonization over 2 thousand years ago, inherited neither the ruthless militarism of the Inner Core, nor the pioneer spirit of the Frontier, and so have a deeply isolationist culture. It is because of this that they have only now taken notice of the Empire, and even then are united only reluctantly.
The Solar Federation is ancient, older than the colonies themselves, but for the longest time has been mired in bureaucracy and petty politics. It is only recently, as the corruption and decadence of the old democratic government has lead to it's abandonment in favor of the military, that the power of the homeworld has been unleashed. Now rapidly consolidating power both in and out of the Inner Core, the "Federation" careens towards total war with the more powerful Mechanist Coalition.
That Mechanist Coalition, one of the first superregional entities to exist, is built off of the cultural similarity between worlds whose reliance on machines goes far beyond the otherwise socially acceptable. Correctly anticipating the rise of Earth, the Coalition has spent a century militarizing for the inevitable confrontation.
A lot has changed since the rise of the Lativerian Empire, and the galaxy is now in a period of extreme turmoil, as the Terran Empire, who conquered all, has partially collapsed. As the vassals of the old Empire move to fill the power vacuum, the future of the Galaxy, at least for a time, seems uncertain, as the Empire's position has stabilized in the Orion sector. While not as 4x like as the 340 scenario, this scenario is good for more dynamic and hectic gameplay as the interstellar order is in the process of being turned on it's head.
The Terran Empire has a legendary starting position, once holding sway over the whole Domain and now reduced to Orion and Perseus, it is nonetheless by far the strongest Empire at the onset of 548. Unfortunately, that dominance is waning, as the Empire's former vassals have not forgotten their oppression, and observe in tense silence the Empire's actions. Further weakened by overextension and infighting, the Empire of Man's remaining life will likely be that of total war.
Having thrown off the Empire's shackles, the 2nd Solar Federation was founded after the Inner Core had been cast into the dual extremes of bureaucratic decay and imperial eminence. Now looking for a return to moderate, democratic politics, the northern Solar Sector stands united to face the Empire in battle.
After the death of Emperor Lativerius I, his Empire fractured into multiple feuding kingdoms, each vying for the imperial throne. Then engaged in civil war, the kingdoms failed to put their differences aside to confront Earth's new Order, and as a result, paid the ultimate price. Now having thrown off the Terran boot, the 2 remaining kingdoms barely refrain from civil war, hoping to cast aside the Empire of Man for good, so that they may return to killing each other.
Finally, the Outer Galaxy is tentatively united, like many others, in opposition to the Empire of Man, but as it has only recently received FTL technology, planetary separatism is extremely high, and even against the far more powerful Empire, the Outer Rim Confederacy is in dire straits.
