Technology Level or Tech Level, commonly abbreviated TL, is a measure of technological capability and sophistication.

Please see the following AAB Library Data articles for more information:

Charted Space Technological Spectrum:

Description (Specifications)[edit]

OVERVIEW: Technology Level (abbreviated tech level or TL) is a rating. It rates the capability of typical equipment used by the average citizen on his or her world. The tech level of a star system has a significant effect on its economy and the extent of its interstellar trade. Technology can be a tremendous multiplier for economies of any size as well as a source of enormous prosperity. However, while many technologies have the capacity to bring great prosperity and economic wealth to planet, technology also has the capacity to be tremendously disruptive of local cultures, societies, and peoples. Generally, technology tends to increase the quality of life for the average sophont, but it is not a guarantee. It is very possible for a sophont on a very low-tech world to have a higher quality of life than a sophont in a high-tech star system.

IISS Chronological Periodization[edit]

Epochal Technological Periods[edit]

On a very broad level, Imperial historians, scientists, and scouts have divided contemporary and future history into technological epochs and periods. This chronological periodization also projects where future technological trends might be found as evidenced by Ancients technology and that of other Precursors:

Epochal Technological Periods Overview
Period Name


Periods (TLs) Technology (Kardashev) Scope Key Technologies General Period Remarks

(Emergent Period)

TL-0 Proto-Tech

(K= Type n>0) [Hemisphere Mastery]

Very early societies with basic "found object" tools and a planetary (world) scope. Tools, mysticism, proto-science, proto-culture, proto-art, band societies, caves, etc. Alpha Period These species have made the jump from creature to sophont. They are new to technology, and are beginning to use it to develop new societies and civilizations.
  • Some call them Stone Age.
Low Sophontic

(Foundational Period)


(K= Type 1)
[World Mastery]

Foundational technologies with planetary-systemic (intrastellar) scope. "Tools making tools or made objects." Steam engines, celestial navigation, urban sanitation, factories, interchangeable parts, ICE engine, electronics, spacecraft, fission power (nuclear), etc. Ur Period Minor Races frequently establish successful civilizations in this range, often with very capable spaceflight programs and sleeper ships.
  • Some call them Space Age.

(Interstellar Period)


(A to J)


(K= Type 2)
[Star System Mastery]

Interstellar technologies with an polystellar (intragalactic) scope. FTL, fusion power, advanced manufacturing (Makertech), advanced medicine, cloning, lethetic robotics, early nanotechnology, advanced artificial intelligence, etc. Stellar Period All of the Major Races possess interstellar technology within this range, with the current vanguard at TL-15.
  • Some call them Interstellar Age.
High Sophontic

(Ultra Period)


(K to T)


(K= Type 3) [Galaxy Mastery]

Galactic technologies with a polygalactic scope. Transgalactic FTL, antimatter power, highly advanced biotechnology, advanced nanotechnology, true artificial intelligence, etc. Galactic Period Some believe that the Kursae, despite their lack of a Jump Drive were able to achieve many of these advances.
  • Some call them Galactic Age.

(Astrodeific Period)


(U to W)


(K= Type 4) [Universe Mastery]

Astrodeific technologies with a universal scope. Planet-bending, geneering (sophont creation), nano mastery, etc. Transgalactic Period Most technological researchers believe that most of these technologies were within reach of the Ancients.
  • Some call it the Age of Space Gods.

(Bhodhisattivan Period)


(X to Z)


(K= Type 5) [Polyuniversal Mastery]

Bhodhisattivan technologies with a polytemporal, trans-dimensional scope. Chronotaxis (time travel), dimension-hopping, reality mastery, etc. Omega Period Most technological researchers believe that most of these conjectural technologies were beyond even the Ancients.
  • Some call it the Age of Elder Races.

(Post-Technological Period)

TL-34+ PTP

(K= Type 'Post-Omega') [Unimaginable]

This sort of technology is beyond imagination. This sort of technology is beyond imagination. Post-Omega Period This sort of existence is beyond imagination. Often known as the hypothetical Post-Technological Period (PTP).

Average Tech, Mastered Tech & Research Tech Levels[edit]

Average technologies in common use within the Third Imperium are very often considerably lower than the high end of (TL-15 or TL-F) Imperial technological achievement.

Each of the polities of the major races has a different average, sustainable technology level, but most systems and worlds average in the TL:10-12 range, with the most capable, higher tech worlds averaging in the TL:13-15 range.

Tech Levels 0 through 21[edit]

This TL table is a list of technological levels and short descriptions. The descriptions correlate TLs to periods in history or alternately, future technology.

Tech Levels 22 through 33[edit]

Levels above 21 are the Accelerating Tech Levels: each of them tends to be of shorter duration and each leads at an ever-accelerating pace to the next. The technologies addressed by TLs above 21 are frighteningly powerful and exceptionally susceptible to disaster. As a society progresses to each new Accelerating Tech Level, the focus shifts to a different technology.

All advancing technological levels are Accelerating Tech Levels to one degree or another. Many scientists within Charted Space argue that the concept will apply most significantly to the TL:19-27 Ultra Period or higher. Others argue for any level above TL-22.

The Singularity (TL-34+)[edit]

When the society moves beyond TL-33, it reaches the Singularity. Some think of it occurring within the TL:31-33 technological epoch. Noone really knows, or if they do know, they aren't telling. The technologies focused on for the past thirty-three TLs are strong indicators of the fate awaiting the culture. A focus on more warlike technologies points the society towards destruction, while a focus on peaceful engineering disciplines tends to point the society towards survival. A balance of the various technologies available may result in ascension to a post-technological existence.

History & Background (Dossier)[edit]

The Third Imperium's most advanced technologies in common use are (TL-15) technologies. Some cutting-edge worlds have achieved an unsustainable, theoretical (TL-16) rating, but are not yet in wide usage. The Darrians or Daryen are a prominent example of such a society with access to TL-16 technologies.

Technological Epochs[edit]

The scientists of Charted Space have, more or less, agreed upon a vision of the future outlined below. Who knows if the future of Charted Space will resemble these projections?

Technological Epochs
TLs Hierarchical
Epoch Hallmark Sophontic Period Smelchakian Period Key Indicators Remarks
TL-Negative Pre-Sophontic Period Pre-Sophontic Period Pre-Sophontic Pre-Sophontic Period Pre-Historic Period (PHP) The Rise of Life. Creatures. Pre-technology lifeforms.

The ability to visit other universes changes society profoundly. Entirely different astronomical environments engenders new viewpoints.
TL:31-33 Omni Tech Epoch Pocket Universe Epoch Trans-Sophontic Epoch Omnipotential Period
(Omega Period)
Chronotaxis & Transuniversalism. The ability to create and manipulate pocket universes infinitely expands available resources and turns all but the most adventurous inward. Time travel heralds the Singularity. Technological existence is forever transformed. Multiple possible existences motivates sophonts to seek existence beyond technology.
TL-34+ The Singularity PTP Post-Sophontic (Post-Omega Period) The Singularity & PTP. Society reaches a critical point in its development. Beyond imagination. Beyond technology. Beyond any previous definition of life.

Technological Metrics[edit]

The Technology Levels of the Third Imperium are measured in the range TL:0-15 (0-F), with TL-1 representing extreme primitive levels (hunter/gatherers), and TL-15 the height of Imperial technology.

Chronological Periodization[edit]

In proper IISS parlance, the following terms are used. Historians and journalists often use them in a more figurative or extended sense.

Smelchakian Chronological Periodization
Chrono-term TLs Remarks Example/s
Age 1 Synonymous with a TL or a passing paradigm and society. Zeitgeist.
  • There is no set chronological span of time for this technological evaluation.
(Age of Nomadism → Age of Farm & Village → Age of Town & Market)
Epoch 3 The typical longevity of a mature society before it undergoes paradigmatic change through revolution and societal evolution.
  • An epoch almost always is composed of three ages.
  • There is no set chronological span of time for this technological evaluation.
(Agricultural Epoch → Industrial Epoch → Information Epoch → Interstellar Epoch)
Period 9 Part of the development of a maturing civilization.
  • In late periods, less than 9 TLs may be involved due to a quicker pace of knowledge acquisition.
  • Typically 9 TLs although some periods may encompass fewer, but a longer chronological span with less technological advancement.
  • This typically encompasses three epochs.
  • There is no set chronological span of time for this technological evaluation.
(Foundational Period → Interstellar Period → Ultra Period)
Era 28 to 30+ The typical lifespan of a mature, technological civilization.
  • Typically 30 TLs although some eras may encompass fewer or more TLs depending on the civilization and their rate of technological advancement.
  • This typically encompasses three periods and a transition epoch.
  • There is no set chronological span of time for this technological evaluation.
(Sophontic Era → Trans-Sophontic Era → Technological Singularity)
Eon 31 to 33+ The typical lifespan of several mature and advanced technology civilizations.
  • Typically 33 TLs although some eons may encompass fewer or more TLs depending on the civilization and the Singularity.
  • This typically encompasses one era and a transition epoch.
  • There is no set chronological span of time for this technological evaluation.
[Pre-Sophontic (Creature Existence) → Sophontic (Technological Civilizations) → (Technological Singularity) → Post-Sophontic]

Paradigm & Period[edit]

Each period represents a loose set of standards and cultural mores for a civilization. More than one period ahead represents a severe change of societal possibilities that significantly less advanced societies would probably think of as "magic" or the "work of the gods."

  • One period ahead represents the dreams or near-technology science fiction of a preceding people, what one might call a paradigmatic shift. Significantly more advanced societies will often appear exceedingly strange or difficult to comprehend to peoples with lesser technologies.
  • Higher technology societies and civilizations will very often find lesser technology peoples to be backward and primitive.
  • Please see Detextualized Paradigmatic Problem and Clarkian Postulates for related ideas.
