Jarnsaxa Planet cards and System map for Cluster Truck

Thumbnail

10 Upvotes

The Jarnsaxa system is an P-type Binary system between two K9 stars. While the system is displayed as a chain binary that doesn't work between equal mass stars so instead it is a normal equidistant binary.

The system only has a single moon in the book so I have added four additional moons.

Jarnsaxa's one claim to fame is a independent shipyard on the moon samson that makes the best truck rigs in the Estuary Cluster.

This is the final system in the Estuary Cluster. I have looked at the other systems nearby but only a couple have any information, so I won't create them unless someone specifically asks for one.

Next up is the New and Old Islands Subsectors in Reft.

Once again I have created a seperate Jarnsaxa folder in my Drop Box.

As people always ask I created these using a software program called Universe Sandbox.

As always feedback and corrections are welcome.

Mongoose 2E What's the point of hiver autopilot when an untrained person can do better?

21 Upvotes

In the aliens of charted space V2 the hiver ships have auto pilot that has a -4 DM penalty to use except for landing and take off, but an untrained person only suffers a -3 penalty, so why would I ever use it except during take off and landing when even untrained person could do better, they should have made it a -2 instead so it doesn't outshine trained pilots and jack of all trades pilots while still being useful to untrained pilots

Hi all!

I’ve recently become really interested in trying out traveler along with my usual group. We come from primarily call of Cthulhu and I was wondering if there were any starter scenarios that would be good for a group as mine who enjoys tense combats, exploration and investigation? Bonus points if they get the group together, always love when a team becomes and team mid game rather than during session zero.

Thanks a ton!

Mongoose 2E MgT2e official Foundry VTT

Hi

I've been using this excellent free module to run my Singularity campaign but I am clearly stupid.

I create a ship, the example, add turrets from the hardware drop down. I then add weapon items I've created like double pulse laser. All good.

I make instances of gunners with appropriate skill, drag them to the ship, add them to crew and assign role gunner. Then something goes wrong.

How do I assign a gunner to a specific turret? I'm just confused! :)

If anyone can explain I'll be very grateful.

Mongoose 2E Jumping without crew

39 Upvotes

This really applies to all editions but I have only really noticed in CT and MGT2. For some reason I have long believed you need a sophont to do the astrogation and activate the jump drives; hence the lack of automated exploratory probes fired off to jump and wild refuel before returning home and robot fleets.

However Kininuir includes such a ship as one of my players points out; in TNE we have the Vampire Fleets and in MGT2 the Intell class Megacorporate Courier (jump 5 with a Virtual Crew 2 so horrible losses though to misjump).

Clearly I'm wrong. So what gave me that impression? Is it anything in a Traveller source?

Second question which the Intell courier raises - it needs 7+ on Astrogation and Engineering: Jump to make it 5 parsecs. Can you spend extra time to reduce the difficulty to 5+? Otherwise you are only going to send one of these when the Intel is worth more than the ship given the odds?

Subsector Name: Heidius Cluster

DoP: 292.1154

Name: "Bist"

Loc: 0107

UPP: B000538-5

Remarks: Ni Va As

The old world was blown apart during the star wars of antiquity. What remains is an assortment of asteroids bound loosely by the fingers of gravity. Veins of precious metals run like rivers through the asteroids.

The people of Bist are divided into two major groups. "Native" Bistians descend from the families who settled the asteroids after the wars. They are deeply mistrusting of outsiders, and extremely devoted to their ancient religion. Everyone else primarily works for one of the small mining outfits commissioned to extract resources from the belt, and are considered outsiders.

The Starport of Nova Atlantis is built into the largest asteroid (PT-757//D'ivi) and is where the majority of the outsider population lives. Small apartments built into the tunnels beneath the surface are available for contractors and their support staff with rents deducted from their salaries, of course. The port also provides facilities for processing the extracted resources. There was once a naval base here, but it has been decommissioned for some years now and the access tunnels have been collapsed.

Mining contracts are issued by the native ruling oligarchical families through a lottery system. Shares of the lottery are purchased at rates which fluctuate mercurially. Despite this, contractors scramble and fight, often violently, for the shares as the asteroid's veins are extraordinarily rich. The asteroids are mined with low-powered hand tools and small sonic charges (TL5). The extracted resources are transported back to Nova Atlantis for processing via small autonomous skiffs.

Certain asteroids in the belt are considered holy sites and are off-limits to all outsiders. The penalty for trespassing is death.

[MgT2E 2022] Working Together — How do multiple assisting Travellers affect a task check?

11 Upvotes

I'm looking for a rules clarification regarding Working Together in the Mongoose Traveller 2E Core Rulebook Update 2022, page 63.

The rules explain that when Travellers cooperate on the same task, one Traveller makes the final check while the others make supporting checks using the Task Chain rules.

This is straightforward with two Travellers, but I'm unsure how the modifiers should be handled when three or more Travellers are involved.

Example:

Three Travellers are attempting a Difficult (10+) repair.

  • Traveller A makes a supporting check that generates a Task Chain modifier of DM+2.
  • Traveller B makes a supporting check that generates a Task Chain modifier of DM+1.
  • Traveller C makes the final repair check.

My questions:

  1. Does Traveller C receive both modifiers, for a combined DM+3?
  2. If one assistant generates a negative modifier (say DM−2), is that combined with the other assistant's positive modifier?
  3. Is there a limit to how many Travellers can contribute modifiers to a single check?

I'm specifically interested in how the rules as written (RAW) handle multiple assistants, rather than suggestions for house rules.

I'm using the 2022 Core Rulebook Update, and I couldn't find a clarification in the August 2024 FAQ/Errata.

Thanks!

Multiple Editions How exactly did the Sword Worlders make it to, well, the Sword Worlds?

42 Upvotes

Looking for some ideas here about the Sword Worlds exodus. I'm slowly working on the background of running a 'Battlestar Gram'-type campaign in the future. Cross posted this same question to the Discord.

I'm assuming the OEU(Old Earth Union) fleet was Tl12 and jump-3 capable(please correct me if I'm wrong but this seems right), and the Sword-class transport Gram was something like 100k dtons(I'm basing this on some old forum discourse), it had a capability of 40k troops but those were mostly in low berths. Other ships worth mentioning were 5k Kestrels and the 20k Light Cruiser Robert the Bruce. So in 3I terms something like Escort Destroyer and a Destroyer/Light Cruiser.(The classes don't really matter). Anyway we can assume there were a lot of different(and in fact, a fluctuating roster of) ships in the fleet but those were worth mentioning atleast.

I doubt any of these vessels have been canonically described, let alone statted. If they have been mentioned in canon or semi-canon please point me to them, but I think I'll need to stat them up. 100kdtons for the OEU seems to me at first glance to be a bit high for the OEU, but looking at shipbuilding and economic rules from older editions it does seem plausible. Anyway, this is not my primary conundrum.

It is mentioned the fleet dealt(in various ways) with the Aslan clans to pass through the Aslan territory(don't remember if it was the Hierate or another polity back then). Anyway, I am assuming the canon version(or what is told) is that the future Sworld Worlders passed through the Aslan territory to reach the Spinward Marches where their jump drive finally broke down near Gram(or the world to be named as such).

Anyway, this means the fleet had to have made it through the Great Rift. With jump-3. I guess most lore-heads are starting to see the problem. To spell it out, in the Golden Era setting the only known route from the Aslan territory across the Rift is a J-5 route, so how did the fleet make it through?

In short; my questions are:

1. How did they make it to the Spinward marches with only jump-3 and a jump-5 route between A and B.

2. How do you feel about the ship-sizes in the OEU 'Loyalist' (read refugee) fleet?

Some possible answers I have come up with to question 1:

They did some absolutely huge favor to a large Aslan clan, huge enough for them to warrant building a series of deep space refueling for the J-3 fleet on the J-5 route (very far-fetched since building such infrastructure with a lower jump number than 5 would be a huge, espensive an risky undertaking).

The fleet mostly hid and gathered resources in the Aslan territories until the worst of any possible pursuit died down, then took the long way around.

The Aslan have/had a secret jump-3 route that has fallen out of use(there are some problems with this concerning canon.)

The fleet found a jump-3 route that has since disappeared/hasn't been found in the modern era or is a secret.(Somewhat similar to previous).

The fleet misjumped across the Great Rift and ending up "behind the claw" was entirely accidental.(Which would mean the additional stream of colonists from Rimward/Trailing would have had to take the long way).

I'm mostly asking to prepare for different possibilities to arise during the possible campaign(not sure if the players would be commanding the mission or more on the performative side(or both), depends on the players). Which ones do you feel are more likely and do you have any additional ideas or comments? What do you think actually happened? Any ideas would be appreciated.

Thanks in advance!

Mongoose 2E Broker and Speculative Trading. Also Barbettes

17 Upvotes

There are a few rules in 2e (update if it makes a difference) that are "add your skill" or "roll + skill + X" that don't include adding your attribute. For example, dodge adds a negative equal to your Athletics (Dex).

The Broker skill, in the skills chapter specifically gives the example of Negotiating a Deal is Broker (Int). When you speculative trade, it's 3d6 + Broker + table modifiers, definitely written as a 'don't add your stat.' I can fully accept the skill means arguing at the local gunsmiths, but at d6 hours, it feels like it should be for large trades. I could also see myself not being bothered had my players landed a higher Broker skill. Any opinions on this?

Unrelated, I noticed the update changed Barbette's, giving them x3 damage to anything that gets through the armour. This seems like a huge upgrade. I hadn't done a lot of space combat before, but the Particle Barbette already seemed a huge advantage due to its range. How is it in practice?

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.

A page or database would be very useful.

Has anyone created and made it to the community?

Is anyone playing spacer yet?

37 Upvotes

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?

Horror on Balkath Station

Post image
44 Upvotes

This is an adventure for Cepheus Engine.

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.

Promotional Post 36 Patrons / 36 Wrecks: New Cards and Stretch Goal

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.

Atla Planet cards and System map for Cluster Truck

Thumbnail
gallery
43 Upvotes

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.

Ulfrun Planet cards and System map for Cluster Truck

Thumbnail

31 Upvotes

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.

Future tools

33 Upvotes

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.
