The United Lexen Empire is not an empire, as such- it is a treaty, a unity of billions of nations spread throughout space. A unity, yes- but often a fragile one.
These billions of nations are not simply the spawn of one particularly ambitious species. Space is filled with many unique sapient species, each with their own fragile home ecosystem. From the folds of the giant Milky Way, to the humble Sagittarius Dwarf Galaxy and Large Magellanic Cloud, the United Lexen Empire teems with life.
But one explorer alone cannot document the immensity of the cultures and ecosystems in the ULE. So, we will largely focus our efforts on a single, relatively small area of space.
The local systems are a cluster of inhabited star systems, all contained within a sphere with a circumference of ~1000 light years, a variety of uninhabited systems among them. The closest inhabited star system not dedicated to trade is ~3000 light-years away, so the local systems form a natural group; sort of akin to an island chain separated from others by an ocean voyage. The gap of mostly uninhabited space around the local systems is known as the stellar pacific.
Inhabited in this context does not count trade planets or research outposts; nor does it count planets with inhabitants that have not been discovered by the local systems yet. There is plenty of trade and research going on in the stellar pacific, and the local systems area will likely be expanded as more sapient species are discovered and contacted in the surrounding star systems.
