Traveller Version

A Timeline is a listing of significant historical events within the setting, in this case, the OTU.

  • The specific chronological periodization used varies between the term era and milieu. Sometimes mileu is pluralized the French language way as Mileux rather than with the standard Anglic method of pluralization.
  • The chronological timeline is specific to the overall sweep of Charted Space. The Technology Levels or Technological Timeline are specific to each race of sophonts.
  • The timeline here exists because of the immense work poured into the Traveller Integrated Timeline.
  • Please also see Setting.

Description (Specifications)[edit]

The broad sweep of history is divided, roughly, into TEN eras. These eras are largely based upon the rise and fall of Humaniti and their empire of the stars. While other races, particularly the other Major Races, may have a differing division of eras, the Imperial Encyclopedia uses the Humaniti-centric one.

Tracking With Real Time[edit]

From the first adventures in the Imperium, Traveller has linked the setting time in a 1:1 relationship to real time. Specifically, the OTU calendar year 1105 was created in 1979, and each day added one day to the setting as well. As a result, for example, adventures written in 1984 took place in the OTU in 1110.

This presents the ability for groups to coordinate by calendar.

An attachment of calendar date to the various milieux of the OTU can be reset to 2020 as follows:

Milieux Year to Calendar Year
Era 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 2032 2033 2034 2035

History & Background[edit]

Traveller also contains at least one official canon alternate timeline:

Alternate Timelines: Category: Years of the Imperium Eternal (1117 to Inflection with the OTU Timeline around 1450)

  • GURPS Alternate Timeline — Strephon is not assassinated, the Rebellion did not occur, and Virus was not released. Artificial intelligence still emerges with technology, and the Wave still breaks over Charted Space as usual; the timeline inflects with the OTU somewhere around 1450 Imperial.
