Editing Setting

Each of the versions of '''Traveller''' had one official setting, and others which were developed (usually by different publishers) to a lesser degree. 
* The designers set aside one [[sector]] ([[Foreven Sector]]) for no official development, so that referees could do what they wanted knowing that no future ''Official'' published product would later contradict what they had developed.

== Description (Specifications) ==
[[Traveller]] began its 1977 existence as a universal game system with high ambitions to recreate any classic science fiction [[setting]] or [[theme]]. It was intended to empower referee-gamemasters to create what are now called [[ATU]]'s or [[IMTU]]'s. Traveller's first official setting, what is now called the [[OTU]], started very modestly and grew gradually into the rich, highly detailed background that it is today.

|- valign="top"
| [[Classic Traveller|Traveller]]
| 01st Edition 
| 1977
| Primary Setting/s:
* [[Spinward Marches Sector|Spinward Marches]] 
* [[Solomani Rim Sector|The Solomani Rim]]
* [[Third Imperium]]
| Background (Campaign) Books:
* '''[[The Spinward Marches Campaign|Spinward Marches]] ([[GDW]])'''
:The [[Spinward Marches Sector]] is a frontier region bordering the [[Zhodani Consulate]], and site of the [[Frontier Wars]]. It also borders the [[Vargr|Vargr Extents]] as well as some independent factions such as [[Darrian]] Confederation, [[Sword Worlds]] and unexplored space. This setting allowed for many different types of adventures.
* '''[[The Solomani Rim]] ([[GDW]])'''
:The [[Solomani Rim Sector]] was a more developed region of space where the world of [[Terra]] is placed.
|- valign="top"
| [[MegaTraveller]]
| 02nd Edition 
| 1986
| Primary Setting/s:
* [[Diaspora Sector]]
* [[Third Imperium]]
* [[Rebellion]]
| Late in its existence '''MT''' introduced the [[Diaspora Sector]], a part of [[Imperial Space]] that lies between all of the major combatants of the '''MT''' civil war. Diaspora was introduced in the [[Hard Times]] sourcebook that described the general state of the [[Empire]] and gave rules to simulate the 11 years of war between [[1117]] and the then current setting of [[1128]]. It also described Promise and the surrounding worlds in detail.
|- valign="top"
| [[Traveller: The New Era]]
| 03rd Edition 
| 1992
| Primary Setting/s:
* [[Reformation Coalition]] 
* [[Fourth Imperium]]
| '''TNE''' starts in [[1200]] with an [[Empire]] in ruins. Set close to the [[Hard Times|Hard Time]] setting (Promise actually features heavily in the Storyline) the region was a badly damaged war-zone even before the [[Final War]]. The space close to the basic setting ([[Reformation Coalition]]) is well detailed and good maps exist.
|- valign="top"
| [[T4]]: [[Marc Miller's Traveller]]
| 04th Edition 
| 1996
| Primary Setting/s:
* [[Core Sector]]
* [[Milieu 0]] 
* [[Sylean Federation]]
| '''Traveller 4th edition''' (also refered to as '''T4''') establishes [[Milieu 0]] where the [[Core Sector]] is used as its setting. Set around the time of the founding of the [[Third Imperium]] ([[0]] to [[200]]), the setting focused on the [[Sylean Federation]] and its attempts to conquer or absorb the worlds around it. Given the depths of the [[Long Night]], the setting included the classic [[wikipedia:4X|4X]] (explore, expand, exploit, exterminate) gaming style in an RPG.
|- valign="top"
| [[GURPS Traveller]]  
| 05th edition 
| 1998
| Primary Setting:
* [[OTU|General OTU]]
| Set in an "alternate" [[Traveller Universe]] in which [[Strephon|Emperor Strephon]] was ''not'' assassinated, thus the [[Rebellion]] and subsequent [[Final War]] never happened, '''G:T''' added a lot of material to the classic [[sectors]] of the [[Traveller Universe]] while advancing the [[timeline]] about 15-20 years from the [[Classic Traveller]] set. 

Three of the most relevant GURPS Traveller books are:
* '''[[GURPS Traveller: Behind the Claw]]'''
:[[Spinward Marches Sector|Spinward Marches]] where the {Imperium}, [[Zhodani]], [[Vargr]] and more alien races interact.
* '''[[GURPS Traveller: Rim of Fire]]'''
:[[Solomani Rim Sector|Solomani Rim]] and its war-torn past.
* '''[[GURPS Traveller: Sword Worlds]]'''
:[[Sword Worlds Confederation]] and its history.
|- valign="top"
| [[GURPS Traveller: Interstellar Wars]]
| 06th Edition 
| 2002
| Primary Setting/s:
* [[Interstellar Wars]]
* [[Ziru Sirka]]
* [[Terran Confederation]] 
| '''GURPS Traveller: Interstellar Wars''' covers the 200 years of war, peace, and overwhelming change as the ancient [[Vilani Imperium]] falls to the upstart [[Solomani|Terrans]]. In this time of conflict, the opportunities for adventure are more exciting than ever before! Forge new trade routes within the {Imperium} itself. Defend the homeworld from invaders during the [[Siege of Terra]]. Make first contact with alien races. Help guide the [[Terran Confederation]] in its expansion from a single planet to a [[sector]]-spanning [[empire]].
|- valign="top"
| [[T20|Traveller D20]]
| 07th Edition 
| 2006
| Primary Setting/s:
* [[Domain of Gateway|Gateway Domain]]
| '''T20''' introduced the [[Domain of Gateway|Gateway Domain]], one of the backyards of the [[Empire]]. A mix between {Imperial} worlds and various [[client state]]s this is closer in basic feeling to the [[Spinward Marches Sector|Spinward Marches]] while lacking the "big guys and old grudges" that are a common theme there. 

Set in the [[900s]] (about 150 years before [[Classic Traveller]]) it has a lower [[technology level]]. Add in that the [[Solomani Rim War]] is close enough by to draw away troops and attract Raiders and the result is a rather gritty and dirty universe along the lines of '''Babylon 5''' rather than the relatively clean [[Spinward Marches Sector|Spinward Marches]].
|- valign="top"
| [[Traveller Hero]] 
| 09th Edition 
| 2006
| Primary Setting/s:
* [[OTU|General OTU]]
| Traveller Hero does not have a milieu of its own but instead covers several previous milieus including [[Milieu 0]], [[T20|milieu 1000]], [[Classic Traveller|milieu 1116]], [[MegaTraveller|the Rebellion]] and [[The New Era]].
|- valign="top"
| [[Mongoose Traveller]]
| 10th Edition
| 2008
| Primary Setting/s:
* [[Spinward Marches Sector|Spinward Marches]]
* [[Foreven Sector]]
| Mongoose Traveller returns to the "Classic" era and location, i.e., 1105 and the [[Spinward Marches Sector|Spinward Marches]]. Although the Basic Rule Book has little setting background, the first supplement released was [[Mongoose Traveller: Spinward Marches|The Spinward Marches]] by [[Martin Dougherty]].

Mongoose has also announced that the [[Foreven Sector]] will be the third party development area. Because of the ''Traveller'' license, third party publishers who wish to write Traveller materials will need to either publish through the Mongoose imprints or write their material to fit in the [[Foreven Sector]].
|- valign="top"
| [[T5|Traveller5]]
| 11th edition 
| 2013
| Primary Setting/s:
* [[Galaxiad]]
| The Galaxiad, set in 1900 in [[Charted Space]] and beyond.

== History & Background (Dossier) ==
'''Traveller Version Terminology:''' Over the years, GDW employees as well as the associated Traveller community developed a number of terms and codes to signify what sort of Traveller universe they preferred. 

These terms and codes include:
* '''[[OTU]]:''' ''"Official Traveller Universe."'' Traveller as published. due to the number of alternate timelines now available, this term now tends to refer to the original [[Third Imperium]] setting from the years ([[1100]] to [[1117]]). 
** Please see '''[[Setting]]''' and '''[[OTU]]''' for more information.
 
* '''IMTU:''' ''"In My Traveller Universe"''. A reference to the particular customized game setting/rule mechanics used by any particular Traveller fan/player. 
** '''ATU:''' Alternate Traveller Universe.
** '''IYTU:''' In Your Traveller Universe.
** Please see the pages for '''[[Traveller Mailing List]]''', and '''[[Traveller Mailing List/FAQ]]''' for more information.

* '''Traveller Geek Code:''' There is a special code for a player's '''IMTU''' (''In My Traveller Universe'') called the "Traveller Geek Code". It's a way of describing how your own Traveller universe is constructed (...and how it might vary from the 'official' [[OTU]] universe). 
** Please see External Link '''[http://eaglestone.pocketempires.com/imtu.html Traveller IMTU Geek Code]''' for more information.
