Official Traveller Universe

The Official Traveller Universe (OTU) is comprised of materials published by licensees, although these may be decanonized or overwritten by later materials. The following section is presented in roughly chronological order to illustrate the evolution of the OTU data corpus over time.

Ongoing review and development of the OTU is being coordinated by the Traveller5 Sector Survey (T5SS), an effort driven by Marc Miller to stabilize, correct, and control the UWPs of the OTU so that there's a solid canon base of data for future reference. Feedback should be directed to: Citizens of the Imperium: T5SS Semi-Official Thread

Sectors of the Third Imperium

Old Expanses sector designed by Jim Cunningham and Gordon Sheridan. Portions of Old Expanses sector originally appeared in High Passage Magazine.

(Sectors marked with * do not contain worlds of the Third Imperium.)

Ten subsectors of Trojan Reach sector were further detailed by Mike Jackson and appeared in Third Imperium fanzine.

Several sectors were further detailed in issues of The Travellers' Digest published by DGP, by James Holden and other authors. These include: Deneb (James Holden, Mike Mikesh, and Nancy Parker, #1, #2, #19), Corridor (James Holden, Phillip Athans, Mike Mikesh, and David Riddell, #3, #18), Vland (Nancy Parker and J. Andrew Keith, #4, #5), Lishun (#6, #7), Core (#8, #9, #10), Massilia (Nancy Parker and Robert Parker, #11), Old Expanses (Nancy Parker and Robert Parker, #12), Magyar (#14), Daibei (#15), Reaver's Deep (#16), Dark Nebula (#17), Ealiyasiyw (James Holden, #18), Riftspan Reaches (James Holden, #19), Trojan Reach (James Holden, Mike Jackson, and Clay Bush, #20), Reft (James Holden, John Meyers, and Michael R.

The unofficial "History of the Imperium Working Group" (HIWG) comprised of Traveller fans including authors such as Michael R. Mikesh, David Burden and Leighton Piper, added additional data such as world and subsector names.

In Review

The following sectors are in the process of update and review by the T5SS; additional feedback is appreciated:

Spinward Sectors

The Beyond and Vanguard Reaches sectors were designed by Donald P. Rapp and Chuck Kallenbach II respectively, and featured in two approved sector supplements of the same names published by Paranoia Press. They can be found in the Traveller Apocrypha II collection. Revisions have been made by Chuck Kallenbach II, Don McKinney, and Wayne H Underkoffler.

In the Far Frontiers sector, Jungleblut subsector of was designed by J. Andrew Keith for Trail of the Sky Raiders (FASA). Alsas subsector was designed by Bill Fawcett, and published in "Privateer" (Gameplay, April 1983). The remaining rimward subsectors were designed by Dale L. Kemper for FASA, and published in Ares Magazine, Special Edition #2 (TSR), and The Traveller Chronicle #2, #3, and #4 (Sword of the Knight Publications). The coreward eight subsectors were designed by Jim Kundert, originally published in The Traveller Chronicle #5, #6 and #8. Trail of the Sky Raiders and The Traveller Chronicle issues are available through Far Future Enterprise's "GDW" store at DriveThru RPG.

Canopus, Aldebaran, Neworld and Langere sectors were designed by Randy Dorman, based on references in Alien Module 6: Solomani (GDW), Imperial Lines #2 (GDW), MegaTraveller Referee's Manual (GDW), MegaTraveller Alien: Solomani and Aslan (DGP), JTAS Online (SJGames), and Alien Module 5: Solomani (Mongoose).

World placed by Marc Miller: Caesillian (Agent of the Imperium), Pliabriebl (private communication).

Referee's Preserve

Foreven sector has been set aside as a "referee's preserve," with no further official development to be done within the sector. Stellar positions were developed by Greg Videll and Mike Mikesh for the GDW newsletter Imperial Lines. See FFE Foreven Sector Reserve.

Note that only the details in FFE's document are used on the map. Additional details from Imperial Lines such as the borders of the Mnemosyne Principality and Avalar Consulate and the worlds Hollis and Raschev are now considered apocryphal, to allow for maximum creativity by other authors.

Many publishers and creative individuals have developed their own version of Foreven. Here are a few:

Apocryphal Data

The Judges Guild published four approved sector supplements "Approved For Use With Traveller" by GDW, comprising what was called the Gateway Quadrant: Ley Sector, Maranatha-Alkahest, Glimmerdrift Reaches and Crucis Margin. While the names and locations of three of the sectors were retained for the OTU, most of the data was replaced by later publications. The Judges Guild versions of these sectors can be found on the Traveller Apocrypha II collection by Far Future Enterprises, as well as on the map, located far away from charted space: Ley (Judges Guild), Glimmerdrift Reaches (Judges Guild), Crucis Margin (Judges Guild), Maranatha-Alkahest

Chuck Kallenbach II's 1991 updates of the Paranoia Press sectors — which differ from the 1981 editions and the T5SS updates — are present on the map, located far away from charted space: The Beyond (Paranoia Press 1991) and Vanguard Reaches (Paranoia Press 1991).
