Universe Classification is what the Alliance uses to refer to the many universes found in the multiverse, these classifications help to identify them all.
Void Universes[]
As the name describes, these universes have been devoid of life entirely, either though a brutal conflict of some kind or simple entering its' final stages of Entropy, often described as a "Cold place with no light in it, a utter void", despite this (or because of it) these universes have became the sites of many operations, ranging from Prisons and Weapons testing to more illegal operations from groups that otherwise want to remain unknown
Home Universes[]
The name used to describe the 875 thousand universes that had a majority of its population of Pure Combines/Kilominitics, and what made up of the "Homeworlds" of the Empire of the Combine Race during its reign. After the First war, it became an unstable region filled with numerous successor states as well as many Combine Remnant groups being active and heavily supported by the population, but, by the time of the formation of the Multiversial Federation, it have become a stable region once more.
Ancient Universes[]
The name used to describe the 595 thousand universes that was controlled by the Second Human Empire and the Third Human Republic/United Federation of Species, these universes are the remains of the Human, Forerunner and Prothean Interuniversial Empires, however the Ottsels are not included namely because of the fact that their Interuniversial Empire is still alive and active (albeit weaken severally and shattered in more ways than one).
"The Remains"[]
Also known as "The Ruins" and "The Shattered" is the name used to refer to all the other universes that do not fall under the previously mentioned universe classification, these universes are called this because of the fact that these universes and their civilizations are living (metaphorically) in the ruins of the Ancients. These universes also have their own classifications to themselves as their exist a variety of universes within the Remains, but ultimately are found in either one of three universes
- Utopian: Universes that fall under this are often regarded as being either idealistic or near perfect with little to no real problems or hardships faced by any of its' people outside of natural disasters. However, these sorts of universes, like their dystopian counterparts, are tiny percentage of the entire Known Multiverse, with only 2% of universes found falling under this category
- Adiaphorousian: Universes that fall under this are neither overwhelmingly positive or overwhelmingly negative, in essence, a universe that is simply in the middle as their exist in these universe positive and negative aspects to them that range from environmental to sentient behavior, though they too have a range that points them more towards the Utopian scale to the Dystopian but still fall under of being considered either one. By far the most common type of universe in the Known Multiverse making up 96% of all universes found, a overwhelming majority.
- Dystopian: Universes that fall under this are considered some of the worse universes to either be found in or born into, as their exist all manner of horrific and depressing aspects to it, with so many problems and hardships (and horrors) face by the people of these universes that it is surprising that any species, or life in general, managed to survive the horrors in these universes. Thankfully, like their more idealistic kin, the utopian universes, dystopian universes are equally a tiny percentage of the entire Known Multiverse as only 2% of universes found falling under this category.
