Notes (2019)

Tjoneslo, I want to make this happen soon.

• Do you feel it needs to be further discussed or vetted before we do it?

The Lorenverse years span from 1115 to sometime in the 1400s. Otherwise I'm fine with this. Tjoneslo (talk) 20:48, 30 January 2019 (EST)

---

Ok. Thanks.

- Maksim-Smelchak (talk) 10:13, 31 January 2019 (EST)

Tjoneslo, please look at Master Categories Research (2019).

• Any comments or feedback?

Notes (2016)

Tjoneslo, where did the date categories on the base pages to this article come from?

- Maksim-Smelchak (talk) 08:22, 18 September 2016 (EDT)

I used the various historical eras and dates of Humaniti in Charted Space, based upon the various bits of canon. Mostly this was supposed to be used to give broad categories to the various articles, vs the more narrow designed to give more background to a campaign. First, second and third Imperiums, as well as the interstellar Wars and Long Night are all well established as eras. I made up the "Long Silence" and "Rise of the Vilani" for name. If you do a search through the Forums I think you can find the discussions around these names. Tjoneslo (talk) 15:17, 18 September 2016 (EDT)

---

It's all very good and clever, but I think we should re-standardize on what is in agent of the Imperium.

The Third Imperium article has those mapped out if I recall correctly.

- Maksim-Smelchak (talk) 00:37, 19 September 2016 (EDT)

---

Are you referring to this table or this table] ? Tjoneslo (talk) 18:06, 19 September 2016 (EDT)

---

No the overview table that I built in 2015. The historical eras table that Wayne built using Agent.

As far as I can tell, it is the same as the one in Don's timeline.

It's tough mapping out something that has not so much rhyme or structure. Don must have loved it.

- Maksim-Smelchak (talk) 19:39, 19 September 2016 (EDT)

If I'm reading this right we would have the following:

8. Years of the Interregnum (1116 - 1247)

9. Years of the Fourth Imperium (1248 - 1899)

10. Years of the Galaxiad (1900 - )

I fully support making this change. This looks great.

The other thing the division of the Years of the Third Imperium into the 10 sub-parts. I don't think we should split the Third Imperium Timeline into these sub-parts. They're too short for the Timeline, and fit better as Category:Milieus. I like the idea of borrowing some of the names for the existing era's. For example, Category: Era: Milieu 990 looks so much better as Category: Era: Solomani Crisis. Tjoneslo (talk) 21:17, 19 September 2016 (EDT)

---

At that point, I was just doing the best I could to map things out. It was original research so to speak.

I think we should open up discussion on this.

Era Notes (2007)

This proposal should allow all of us to be happy regarding articles in time and space. Please read and comment, I really do want feedback on this.

• All articles will have a "era" category to indicate when they were "written". The following are the "canon" ones, and others can be added as needed:
  • Era: Interstellar Wars => GURPS IW
  • Era: Milieu 0 => T4 era
  • Era: Milieu 990 => T20 era
  • Era: Milieu 1116 => Classic Era
  • Era: Rebellion => Late MT
  • Era: New Era => TNE
  • Era: Milieu 1250 => TNE & 1248
  • Era: Milieu 1120 => GT Timeline

AD Dates for Historical Periods

From the T4 Core Rule book, p 8:

• Vilani Era: 4700 BC - 2300 AD
• Terran Confederation: 2100 AD - 2300 AD
• Rule of Man: 2300 AD - 2750 AD
• Long Night: 2750 AD - 4550 AD

No entry for TNE/Recovery/4th Imperium.

Timeline

The broad sweep of history is divided, roughly, into 10 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.

Each of the Era may be divided into one or more "milieus", each between one and two decades long, based upon events of interest to historians.

1. Category: Years of the long silence (-300,000 to -9234)
2. Category: Years of rise of the Vilani (-9235 to -4044)
3. Category: Years of the First Imperium (-4045 to -2421)
4. Category: Years of the Interstellar wars (-2422 to -2203)
5. Category: Years of the Second Imperium (-2204 to -1776)
6. Category: Years of the Long Night (-1775 to 0)
