Rule 4:No Piracy. No illicit sharing of copywritten material, nor links to the same.
This was always a rule but wasn't formally posted until now.
Rule 5:No Low-Effort Content.Content shared in this subreddit should be thoughtful, additive, and effortful. This includes restrictions on memes and AI-generated images, text, music, or videos.
This rule came about after a large discussion on GenAI content. You can find the whole discussion with specifically my explanation for why I chose this rule in the bottom half of this post.
Thank you all for your contributions to this subreddit.
Users are permitted to post one promotional post per week. This is not per product, but per user. If you have multiple products, consider promoting them all in a single post.
Affiliate links are not permitted. You may link directly to products or pages, but not using affiliate IDs.
All promotional/advertising posts must be flaired with the "Promotional Post" tag.
All promotions must be for Traveller-compatible products, services, or events, or those generic enough to be easily integrated into a Traveller RPG. Compatibility with any version of Traveller RPG is allowed.
These rules apply whether a product is for sale or free.
Reddit's general rules must also be followed.
Rationale: We believe that new content is the best way to keep an RPG alive, especially one that has been around as long as Traveller. One of the missions of this subreddit is to permit content creators to promote their work. We also believe that there is such a thing as too much promotion and we want to ensure that ads do not overwhelm other discussions. These rules are designed to balance these beliefs. These rules are subject to change if they don't keep that balance.
If you believe a user has violated any of these rules, you may report the post or comment (though this is not a big enough issue to require any 'ad police'). All interpretations of these rules are up to the moderators. If you don't like a product or the user promoting it, your solution is to downvote and/or block them.
I have seen great tools from many diverse creators/creators.
What I have not seen is a list of all Traveller (or closely related) tools.
Ideally, it would have the creator (reddit handle could be enough), the name (or suites of rules), What it offers (short), URLs, any docs locations, and any github entry.
Just started a community for free computer game aids (r/FreeComputerGameAids) for your favorite tabletop RPGs as a place for those who are creating tools and apps to share them and get constructive criticism on ways to improve them.
So…. I got sucked into spacer by just buying and downloading the rules. I really like it. Ive generator a few characters and yes had one die before getting out of the navy. I guess I’ve lived. I wanted to say how much I’m enjoying it. I played traveller back in the 80s and I think spacers rules while influenced on classic traveller still belie an 80s view of the future as evidenced by some of the equipment but still I’m LOVING it! I don’t know the author but he did a good job making this playable while balancing universe creation. I’m finding the rules lend themselves to solo play and I don’t know if this viewed poorly here but ChatGPT also has a character and I’m fighting letting it GM. LOL. All in the name of fun! Is anyone else here playing it?
On the outskirts of the Sonora sector, along the border with unexplored space, is the Balkath system. This distant star system is a double star with a cluster of twelve planets. None of the planets are believed to be occupied by any life forms. The station orbits the fifth planet in the system around Balkath V which is a strange world with methane seas and a toxic atmosphere. The station has been doing scientific research for the Arkoth Corporation.
Little is known about this corporation or what it actually produces....if anything at all.....It appears to be a recently formed corporation that owns research stations orbiting several planets either along the border or in unexplored space. All appear to be doing scientific research of some sort.
Recently there have been rumors about the one at Balkath V. This one has gone silent apparently. No word has been heard from the scientists there in many months. All attempts to contact the station have been ineffective.
Jack Peterson of the Arkoth Corporation is offering CR 300,000 for travelers willing to visit the station and find out exactly what is going on there. He offers a bonus of CR 100,000 if records related to the scientific research can be retrieved and brought back to him before any competitors might board the station and take them.
We're about a week away from completing our funding for the Cepheus Engine patron/salvage cards. I've finalized (I think) design of the Discovery cards (basically space treasure in the Salvage Deck).
Since we're a little less than $400 away from our second stretch goal, I added a third: 48 NPCs for your Cepheus Engine game. If we can crack the $3200 mark, I'll throw in 12 2-sided NPC cards per deck.
So if you haven't backed it yet, please consider it! I think it's a good deal for some great resources for the table. If you have backed it, tell your friends, gloat to your frenemies, trick your enemies...whatever we have to do to get some NPC cards.
Art on the Discovery card is by JE Shields. Art on the NPC cards is by the awesome Victor Merino. Weird point-crawl diagram is by me. Still not sure if I'm happy with that.
Looking at law levels in the MgT2e book and wondering if law levels are cumulative. Like if cloth is banned at level 4 is it still banned at level 6 and so on.
The Alta system is an S-type Binary system between a small M6 Red Dwarf and a tiny M9 Red Dwarf. Note that the second star wasn't given a size but I made it a M9 to match the map in the book.
The M9 Red Dwarf has no planets or belts so it doesn't have a seperate solar system.
The issue with a M6 Red Dwarf is that it puts out little heat so Atla had to be in really close to the star to remain unfrozen.
Atla is listed as having a weird biology with a corrosive atmosphere and life?forms that sits somewhere between bacteria and fungus but with geochemistry mixed in.
Processing this material produces substances that are corrosion resistant and a good sealant, which is why the planet is inhabited.
Once again I have created a seperate Ulfrun folder in my Drop Box.
Hey Traveller fam, I just found out about Traveller and I wanted to make a thing to help refs manage campaigns. It's sorta a combination of a lot of various Traveller tools out there in the wild, have been kicking it around for a few weeks, still lots of work to go, but wanted to share with a larger Traveller community and ask you to break it ;) check it out at traveller.voyage
The Ulfrun system is an S-type Binary system with two seperate solar systems Alpha and Beta.
The stars orbit with a 0.2 light year seperation making them effectively two seperate systems from the POV of Jumping. In system travel between the two is impossible.
Thought for Referees running a Cluster Truck campaign.
The Ulfrun Beta solar system is almost devoid of sophonts - a few thousand belters work the inner belt.
If you are running a more Firefly style campaign where the attempted annexation leads to armed conflict Ulfrun Beta is the perfect place for rebels to run to. While it has little water outside of ice on one moon it has gas giants for fuel and plenty of asteroids and moons to hide on.
It is also in the center of the Estuary Cluster with access to the two major systems of Estuary and Eyrgiafa.
Note that I have gone over the 20 image limit so the remaining two moons can be found in the Drop Box.
Once again I have created a seperate Ulfrun folder in my Drop Box.
What do a mechanic's tools look like in your Traveller universe? If a mechanic from 2026 saw them, would he recognize them? Hammers and knives from a thousand years ago are very similar to modern incarnations, and the ones from ten or twenty thousand years ago are still basically recognizable. Which tools we use today are so fundamental that their designs will be basically the same in a few thousand years? Hammers, obviously. But also I think the wrench. We're always going to need to fasten things together.
AIRTIGHT is a Traveller setting idea I came up with about a hundred years ago in 1998 or so. This was when I was lapping up sci-fi like Outland, 2010: The Year We Make Contact and Silent Running. These days we have more content like The Expanse, The Martian, Europa Report and of course the world is a little more busy with the recent release of The Expanse RPG, the excellent work being done with StarCluster.
Its available under the TAS so if you're interested in doing some co-development, get in touch or pop along to the development forum on the RPGPUB (or join my Discord). Always happy to talk geek.
AIRTIGHT starts with the idea that we've expanded into the solar system but for the most part we are alone. The first adventure, 12K of ICE, explores the first discovery of life within the solar system. The second, Perihelion, inspired by Oamuamua, explores an ancient wanderer which enters our solar system before exiting again for thousands of years.
A third and fourth adventure (Small Mercy and Deeper Dark) will be released before the end of the year will investigate the consequences of using space as a wild west for medical research and the discovery of a megastructure on the very edge of the solar system, in trans-neptunian space. We will be releasing more about Airtight, including a setting guide, as we build out this world.
You can of course get our Classic Traveller PWYW stuff for absolutely nothing. Our sales go to funding art.
I've created some new weapons for Traveller. I'm assuming in a universe as big as Charted Space, there must be weapons that are extremely badly designed, so I've made a few shoddily designed weapons.
They're all wildly overpriced, have critical design flaws, and genuinely alarming safety issues. I designed them for a Mongoose 2E game, but they should work in any game.
I'm thinking about adding a house rule called 'Talents' to my Traveller campaign, inspired by the Boon system in Mongoose Traveller 2e and T5's Arcane Tasks.
Every Talent either gives you a Boon in a very specific area, something like an extra-specialized ability, or lets you do something exceptional that the normal rules don't allow.
The idea is to give my players coming from D&D some of that character customization and signature-ability fun they enjoy, without turning Traveller into D&D or losing its grounded, skill-based sci-fi feel.
Any advice or suggestions?
EDIT: Apparently there are already rules for what I want in Cepheus Deluxe (Traits). I'll go pick that up and give it a look. Glad I posted this, so I could find out.

I first played megatraveler the dos game back in like 1991 not even ten years old at the time.
Traveler always seemed interesting because it came about in the 80's and because it had janes like vehicles. I feel like computer games then were more interesting because they had hard rules and were unforgiving.
Looking at the audiobook offerings...audible has one version read by a typical professional reader but apparently marc miller himself recorded a version where he narrates the story.
I generally prefer listening to audiobooks narrated by the author because their flow is more natural because they themselves wrote every word.
Why is this? How to obtain the marc miller audiobook of traveler? Are there any other traveler books on audiobook.
Let's hear your explosive decompression stories. Here's mine from our last session.
The captain was in an office on a station that was tearing itself apart. He was already on the floor, already hurt, and the man standing over him had a gun and was asking him, fairly politely, to stay down. Then the far wall peeled back like a can lid. All the air went at once, and they started to go with it.
I told him he had less than three seconds of air and asked what he did. He answered in one breath: the desk is bolted down, so grab the leg of it, mag boots on, helmet on, brace.
Upside, he's alive and he isn't going out the hole. Downside, the other guy's boots clamped down too, his helmet snapped shut, and he never dropped the gun. So now it's two men magnetized to the floor of an office with no wall, in vacuum, picking the argument back up where they'd left it.
We're a Stars Without Number game, but vacc suits and sudden hull breaches feel about as Traveller as it gets, so I figure you all have better ones. What's yours? A breach in the middle of a firefight, or a suit with a hole in it nobody caught in time?
If you want to hear how the office went, it's an episode of our show called An Acceptable Loss.
I've been playing and GM'ing for several years but it's mostly fantasy games (D&D, Pathfindrer, etc.) but now I want to run soome Traveller. I've got the Mongoose Publishing version, read it, love it so far!
Can someone recommend a good starting scenario for 3-4 players? I appreciate it.

She is famous, rich, and frail; she is also considered something closer to 'property' than a person at Shangri-La and von Braun. Currently legally declared dead, and on the run from her Disney handlers and 'talent agent', pretends to be an Entertainment Anthroform of herself in public to evade detection. Extreme empathy, low impulse control, and severe rejection-triggered social anxiety are all inherited from her genemod profile.

A smooth-talking know-it-all who runs his mouth off more than is good for him. Absolutely otaku-obsessed with Yulan but trying desperately to 'play it cool' (and constantly failing). Helped Marianne kill a Disney exec, fake Yulan's death, stage an "accident", and flee to the Morpho. Hired by Vance when he bought the Morpho.
“Yulie” was originally a research-assistant agent trained by Geoff; he’s not sure if it (she?) has reached moratorium threshold yet, and doesn’t want to find out. Yulie was sculpted to emulate the behavior and personality profile of Yulan Blossom’s various stage performances, a fact which Yulie and Yulan both find slightly awkward. Yulie spends a good deal of time watching Yulan and adjusting her own behavior (both to better emulate her, and to better distinguish herself from her); whenever the crew needs a ‘body double’ for Yulan, Yulie will load into a Yulan anthroform and perform a diversion.
Since signing onto the Morpho, Geoff has also loaded Yulie with extensive engineering and maintenance skills, allowing her to perform zero-G repairs on the ship when required.
Bodies
When loaded into one of Geoff’s or the ship’s robots, Yulie’s effective physical characteristics are:
Entertainment Anthroform
END -2 / STR -2 / AGI +3
Light Security Drone
END +2 / STR +0 / AGI +4
Heavy Labor Drone
END +6 / STR +6 / AGI -1
Geoff’s workstation can run Yulie at full capacity while controlling one robot body; to control more, Geoff needs to spend around 10 Flops per body per minute (and they need to be close enough to a data center that transmission lag doesn’t degrade Yulie’s performance). Yulie can operate both heavy labor drones simultaneously for tandem operations, but doing so reduces each of their AGI, PER, and INT to -3.

A listener recently asked how I’d approach street-level law enforcement or private-investigator adventures in the Core Sector. So, I made my answer and episode of the podcast.
Signals from the Core Episode 18: Law & Order in the Core
I cover tools and advice for putting an investigation campaign together, from choosing an agency to establishing the investigators’ authority and building cases with multiple leads, plus tips for developing recurring witnesses, informants, and suspects.
Give it a listen, and let me know if you’ve run these kind of adventures in your Traveller games.
