The Third Imperium


The Third Imperium is the greatest interstellar empire in the history of Charted Space. Its Emperors have reigned for a thousand years, building a utopian society based upon the pillars of duty, honour, free trade and a powerful navy that protects its worlds and enforces its laws.

Despite all of its grand achievements, the Imperium has a dark side. It has committed genocide on its own worlds. Its leaders have assassinated and murdered each other in battle to obtain the throne. A civil war nearly tore it apart, ending the dream of its visionary first Emperor. Yet with all the Imperium has been through, it has somehow endured. The Third Imperium is at a crossroads, and choices made now will determine whether it survives or crumbles.

Into this realm enters a bold group of Travellers, seeking fame, fortune and adventure in the hallowed Core sector, the ancient centre of human civilisation, where dreams are made and broken. This book contains everything  Travellers and Referees need to travel and adventure in the heart of the Third Imperium, including:

  • A huge poster map of the Core sector.
  • Detailed descriptions of the people, society, military forces and power brokers of the Third Imperium.
  • The complete history of the Third Imperium as it has never been told before.
  • The Core sector, the heart of the Imperium, including playable human and alien races and world descriptions for all 16 subsectors.
  • New starships, vehicles, weapons, armour and gear for use in Core sector campaigns or anywhere else in the Third Imperium.

The galaxy is rich with opportunity, nowhere more so than at the heart of the Third Imperium. Travellers need only be bold enough to claim their share of the fortune.

Is ok, and not a bad place to start new players (hey, they're near the Imperial Capital...). Its not 'safe and boring', and you can introduce political adventures (and the players might even get to meet the Emperor...). 2 new things to consider tho.
1. Personal energy shields. Not a big thing, any ref worth their salt probably introduced them into his game already.
2. Hydrogen collecters. TL12 and already over a thousand years old. and cheap.
Nice going, Matt. Just make them expensive as hell and it should be fine.

Is this the default setting for Traveller?

The Classic Traveller "Default Setting" historically has been "The Spinward Marches" - Look at "Behind the Claw". It's on the edge of the Imperium, a bit wild & dangerous. The core worlds are a bit more "developed" so the trade routes are more established & pirates are more under control - i.e. not such a good place for a high stakes Firefly style campaign but there are campaigns that can work here

No new careers, but it does include new playable species.

I haven't purchased anything here in ages, because they all say "watermarked PDF," like this title. BUT, it also says "poster-sized map." So is this (and perhaps others) download only, or is it a hardcopy? Would make a lot of difference.

You get the PDFs of both!

All “watermarked PDF” means is that your account name and order number are superimposed onto the bottom-left corner of the pages in the document, in very small print. It gets in the way of absolutely nothing and after awhile you don’t even notice it anymore.

I despise watermarks on my pdfs and use editing software to remove them. Watermarks don’t stop people intent on piracy; instead, they’re an eyesore for legitimate customers.

I really wish publishers would stop adding books with watermarks on dtrpg, just as the music industry realised drm hurt paying customers, not the pirates, and stopped with the drm.

Difference being that DRM sometimes actually interfered with paid customers accessing their products, and a DTRPG watermark is at worst a minor irritation to whiny dingleberries.

I'd disagree, the watermark puts a (small & discrete) barrier in the way of just anybody buying the book then immediately torrenting it. Therefore there will be more legitimate sales because it's less likely to end up on a torrent site - not 100% torrent proof, just less likely.

On to music DRM - the classic Sony rootkit actually installed a backdoor on the paying customer's computer - the bootleg was superior to the official CD.

All the watermark does is identify the purchaser so it acts as a deterrent to torrenters - after all, if I was writing a watermarking routine it wouldn't just be putting the watermark visibly in the PDF, but also encoded elsewhere in the document.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
