'Does a state that falls mean that it has failed? Did the Greater Solar Union fail, simply because it did not survive? It's difficult to say that, when so much of what the galaxy would be is because of them. Without it, life would not have spread as far as it did, nor would it have evolved in such strange ways. Void Islands would be barren, Kinde non-existent. Did it fail? Perhaps it's better to understand the Greater Solar Union not as a failed state, but as a state that laid the groundwork for what would come next. And perhaps that's the greatest lesson we can learn from them.'
Greater Solar Union
Known to those that lived within it simply as the 'Solar Union', the Greater Solar Union refers to a major state within the Vetrarsaer galaxy that existed roughly between -5200 PTE until the Technopocalypse. It emerged from the Voidsea Advent as a federation of worlds that would work together towards common cause, with the capital world being the home of the Kin Kinde, Verdrasil. It is considered a predecessor to the current day Cosmic Union.
The G.S.U was arguably the absolute dominant superpower of the Vetrarsaer before it's collapse - A a key reason why the Vetrarsaer would become so full of life. OIfficially, it's territory encompassed a majority of the Vetrarsaer galaxy, though in practice, it may have been more akin to a patch-work of major bodies across an immense Voidsea. Still, the sheer size of the G.S.U is immense dwarfing any other Faction of it's time. Across it's territory lay wonders, including the terraformation of hundreds of worlds, the seeding of life, and the creation of countless Kinde - Roles they took to with an almost religious reverence. The consequences of this have also, albeit indirectly, factored into why the Sky River Cluster Gyre, and by extension, the Sky Shore, are also teeming with life, due to the Confluence scattering thousands of Void Islands across the Voidsea. Many of these worlds contained life seeded there by the G.S.U, which they spread out across the distant stars.
