Chapter 29 Civilization Tiers

Civilizations are scaled into few tiers:

Civilization tiers are from Halo ranking, you can skip them if you want but it's advised to read them. 

Tier 7: Pre-Industrial

.Societies tend to be small and scattered, driven by subsistence farming, foraging, or hunter-gathering needs. Technology is limited to simple hand made tools, weapons, or agrarian implements and methods, but a very broad understanding of planetary and solar mechanics is not uncommon.

Tier 6: Industrial

Tier 6 is the outset for massive urbanization. Agrarian societies can remain stable in the pre-industrial stage, but Tier 6 population strain and mechanized food production invariably create political and economic pressures very few can balance. Moving past this usually promises advancement. Some societies improve environmental and medical understanding concurrently with mechanical and transport advancement. Those that do not are frequently doomed.

stood on this level from the late 18th to the mid-20th century. This level is also where the were before joining the Covenant.

Tier 5: Atomic Age

Tier 5 species usually begin focusing on clean energy production. The occasional belligerent species will use atomic energy for weapons, often resulting in mass extinctions. In-atmosphere craft are a hallmark, often leading to manned space flight, albeit in a short-scale.

Humanity entered this age in 1945.

Tier 4: Space Age

This is age where species made their first space-flight capable craft. Humanity reached this stage in 1957, when first artificial satellite was launched. This tier is reserved for species with very slow ftl , where years were needed to reach their destination.

T'au's were at this tier when they encountered Humanity at first time.

Tier 3: Space-Faring

Race's with this tier have reached or surpassed FTL . Laser weaponry.

Most civilizations are at this tier. Such as Turian Hierarchy , Martian Union, Saralian Republic, T'au Empire. To be certain some of these race's are barely meeting requirements for this tier, such as Martian Union.

Tier 2: Interstellar

Race's from this tier are by for surpassing level of FTL from Tier 3. Have capabilities to create planet destroying weapons. Having exceedingly accurate Slipspace drive(In Sangheili case).

And manipulation of clean energy.

Tier 2 Civilizations currently are : Covenant (They are using Warp Drive in this fanfic, a very similar drive to Slipspace) ,Sangheili Empire and lastly Human Empire.

Human Empire could be called a peak of this Tier because of few key factors : A fastest FTL Driver in current known Galaxy, Q-Bomb. And other "Unknown Factors"

Tier 1: World Builder

The species has the ability to manipulate gravitational forces, create A.I with full sentience , fabricate super dense materials ,the ability to create life and ability to create worlds.

Species that were in this tier were : Forerunners , Prehistoric San'shyuum and Ancient Humanity.

*Current galaxy doesn't know about the existence of Forerunners, Ancient Humanity and San'shyuum , this level is only theorized . The only one's who know about the existence of the Forerunners are Humans, T'au's and Sangheili for now*

Tier 0: Transsentient

Not much is known about tier. This tier of civilization should be capable of travelling from one galaxy to another.
