The Alliance is a loose federation of 13 different local governments, administering 26 major populated planets across 17 star systems, as well as numerous minor colonies all located within its borders. It is a relatively young entity, formed approximately 400 years ago as a mutual defense pact between the three founding systems in response to aggression from the neighboring Venuma Coalition, which eventually developed into a full government. While most galactic nations have mixes of different cultures within their borders, the Alliance is unique on the galactic stage in that it has no core dominant culture, with many planets being so different from each other that a casual observer might not believe they belong to the same nation.

Member states are mostly autonomous, but Alliance-wide policy is created and disseminated by a political body known as the Core Conference (or “the Core”), which is formed by legislators appointed by the individual member governments according to population. Up-and-coming politicians regularly argue that the weak associations between the members, with no strong central authority, is a recipe for disaster down the line, but the last 4 centuries have seen little conflict from within. The ease of relocation between planets and changes of citizenship for those who are not content where they are, combined with the difficulty of rigid administration across interstellar space without strong force, has left this camp as one of the Alliance's most minor parties.

All members contribute to the common defense of the Alliance's borders by providing ships and crews for the combined Fleets. For most of the Alliance's history, member states have provided their own fleet ships of indigenous design and the crews to man them. Most Alliance crews were not integrated between planets, with most spacers - at least, those not working at the Fleet Command level - spending their entire careers serving with only people from their home world or system. The challenge of managing the repairs, shipyard schedules, modernization plans, and parts inventories for the slew of different ships left many a Depot commander burnt out after only a year and strained Fleet Logistics continuously.

It was only in the last 150 years that Alliance Navy Fleet Command undertook a standardization initiative and commissioned the design of a set of warship hulls across all of the core ship classes to reduce these logistics challenges. These new hulls have steadily replaced the older mixed designs as they reached the end of their useful lives. While it is still not uncommon to see unique designs about the Fleet, they are becoming rarer.
