My 3rd Imperium: History
Official 3rd Imperium History
The Traveller 3rd Imperium setting has an official history with the players starting in year 1105.
which says the 3I has been running the Spinward Marches for c. 700 years. This is too long for the feel I want.
My Alternate Timeline
In my Traveller universe I’m saying it took the 3I longer to expand, roughly an average of 50 years per sub-sector in any direction so as Vincennes in Deneb is c. 16 sub-sectors away from the core say it took c. 800 years to get to the edge of the Spinward Marches.
800: edge of Spinward Marches
900: Trin’s Veil, Rhylanor and Lunion
950: Glisten, Lanth, parts of Regina and Aramis – Jewell seeks 3I protectorate.
1000: Vilis, Regina – Jewell associate
1050: Five Sisters
In progress: building up Aramis, Vilis, Five Sisters, improving route to Five Sisters, Jewell, diplomacy District 268
So Mora has been part of the 3I for c. 250 years, Glisten c. 150, Vilis c. 100 years, Five Sisters c. 50 years – much more frontiery.
The systems in Spinward could have been colonized by
- the Ancients: humans, modified humans or others
- the Vilani
- Second Imperium
- Third Imperium
so large populations aren’t surprising. The Marches are the 3I’s frontier but they are not frontier in the sense of being undeveloped.
Also in between the big empires, alpha systems may have risen and fallen creating their own pocket empires for a time so there cab be ruins everywhere.
In the official history there have been a number of Frontier wars with the Zhodani mostly revolving around Jewell
- two in the 600s
- one in the 900s
- two more in 1080 and 1107
In my alternative time line the first three are bumped up and the second two stay the same
- the first three involved escalating skirmishes in the 950s with the Jewell cluster’s own fleet itself being the largest force
- well planned major Zhodani attack 1080
- 5th Frontier war incoming
1065: second survey
1082-1084: 4th Frontier War
1085 to 1104: a bit less impending war (but potential for salvage, lost ships, spy stuff etc)
1105: standard start, big war incoming
or even way back 800-900 when the Imperium’s border was still in Deneb.
