The Cyrranus System from Battlestar Galactica

[Tenacious-Techhunter]

Yeah, your starship captains shouldn’t have to care whether the package is going to Caprica or Gemenon... they just take it to the “hub”, the space station sitting at the Barycenter, and be done with it. No atmosphere to worry about an insertion, no gravity well to dig yourself out of. Just a simple deceleration and docking.

What are your thoughts if the Cyrranus System was included as part of the OTU 150,000 years later after the events depicted in the 2003 series? What is the best way to introduce this system to players? How should they come across it? Should it be part of the Third Imperium, or should it come out of some unexplored territory?

I would think even if all the humans were wiped out 150,000 years ago, its likely that some humans from the OTU would have resettled here as humans have been travelling in space for a long time. Also would the BSG timeline fit in with the OTU timeline? As far as I can tell there is no problem. There didn't appear to be any alien civilizations for the BSG fleet or the Cylons to encounter, maybe that could change 150,000 years later. What do you think?

 

[Tenacious-Techhunter]

As a purely practical matter, the only viable instance I can see for introducing players to this system is either, by being up-front about it being Battlestar Galactica subsector, or by those players simply being ignorant of Battlestar Galactica on the whole... which probably means they aren’t too into Sci Fi to begin with.

There may be excellent grounds for a crossover here, as you’ve no doubt noticed, but, as with most crossovers, neither fanbase would consider it canon... IE, part of the OTU. And never mind the legal issues involved. This is a strictly Your Traveller Universe thing... and there’s nothing wrong with that, either.

Maybe you should rephrase your question to, “How best can I mesh this with Traveller canon?”; at which point, I’m the wrong guy to answer that, because, to me, Traveller canon is part of the problem.

The one thing I can say is, armed AI-driven Robots put it firmly outside of the Imperium; maybe more like the Solomani equivalent of the Darrian Confederation?

Here's my idea of where to put it. Assume a Dyson Swarm was placed around the entire system of four stars, so the surrounding star systems can't detect it. To them it looks like a planetary nebula thrown off by a long dead red giant, that is now a white dwarf. There doesn't appear to be any habitable planets from a distance. The cloak was placed there by human-friendly mechanical cylons. As you recall from the last episode, they left the humans and the skinjobs on prehistoric Earth, the Mechanical Cylons moved on, but just in case the descendents of the humans on Earth were to build more Cylons, and repeat the destructive cycle, they brought some humans and other animals over to these 12 colonies, they brought them without technology of civilization, nor did they attempt to teach them such. Each of the 12 colonies were seeded with Earth life and humans. Tauron got some Neanderthals. As a final parting gift before moving on to another part of the Galaxy, the Cylons placed a Dyson Swarm cloak around this system so it would not be detected. However if someone were to jump into the system or misjump into the system, the Cylons figured the gig would be up, so upon that eventuality, the Dyson Swarm cloak would self destruct into a cloud of expanding dust and gases, eventually dispersing and revealing the system. I decided that District 268 of the Spinward Marches would be a good location. Someone misjumping into the system or following a "treasure map" to get there sets the whole thing up. I was thinking say for instance the PC's ship misjumps into the system and as a consequence the Jump drive is destroyed, the rest of the ship functions normally, but they cannot effect repairs until they come by some critical spare parts, fortunately this system was discovered by pirates a few years ago, the Dyson Swarm already self-destructed, but the light and radiation revealing this new system has yet to reach the nearest inhabited star system, so for the time being the pirates are keeping their secret. the pirate base has some spare parts that the PCs could use to repair their ship with, in the meantime they can travel all around the Cyrannus Star System, and do some exploring.

 

[Tom Kalbfus]

Lets me explain a little. In the BSG series the Cylons tried to exterminate the humans in this system, they chased the BSG fleet through space as they were trying to find Earth, in the process, some Cylons developed second thoughts about exterminating the humans, and there was a Cylon civil war as well, this culminated with a Human/Cylon attack on the colony of "evil cylons" that were still committed to wiping out the human race, In particular the Model ones were after recreating the secret of Cylon uploading after the resurrection hub ship was destroyed, there was a battle to rescue Hera, a cylon-human hybrid, and the battle ended up with a truce where the humans agreed to provide the secret of Cylon resurrection that was in the collective knowledge base of the "Final Five" cylons that originally came from their version of "Earth" who's civilization was also destroyed in a conflict between skinjob cylons and their own mechanical version of the same. One of the final five murdered the wife of another final five Cylon, so he killed the other when he found out about it when they linked minds, the leader of the evil cylons then killed himself, and by coincidence the colony got nuked, it is not clear whether or how many of the evil Cylons survived, but this was the moment when Kara (Starbuck) entered to coordinates which led the Galactica to our Earth., the fleet then followed. The Humans agreed to give up technology, and they mixed with the native humans already living on Earth. Apparently there was some parallel evolution going on directed by this being known as "God" whoever he may be. Apparently humans evolved on two planets simultaneously, Kobol and our Earth. I was thinking of making Dawn World into Kobol in this case.
http://wiki.travellerrpg.com/Dawnworld_(world)
It is said that Kobol was cursed by God, this Sterility mentioned in the Wikipedia entry might be part of that curse. I think if some paleotologists did some digging around on that planet, they might discover the remains of lost cities and some fossile evidence that humans evolved here, thus Dawn World is Kobol in this version of the OTU. some archeological digging might uncover references to the twelve colonies, and dated charts might lead to its current location with computer projections on stellar drift.

In order for a single statite to block the light from one star from reaching another star, it would have to be bigger than the star it’s trying to block. Even then, that’s not blocking the reflections off the planets.

There would have to be a very practical reason, beyond merely hiding the star system, for such a network to exist. Don’t use handwaves as an excuse for why something is the way it is; justify it practically, or don’t.

"It has happened before and it will happen again," that is a saying from the Battlestar Galactica setting, basically history is a part of an endless cycle played over and over again. The Cylons did this because they suspected that someday the humans of Earth will try to build their own cylons, and the cylons they build would try to exterminate all humans, so what they Cylons did here was try to spread some humans to other planets that they know will support human life, the ones the know about are the 12 colonies, New Caprica, Kobol, Cylon Earth, and "New Earth". For some reason Humans evolved separately on New Earth, and act they attribute to God. The Cylons were trying to spread humanity, while respecting their wishes to stay primitive, out of a sense of guilt on their part for trying to exterminate humans in the first place, this was in part to atone for their past transgressions against God, or so the machines believe. So they did this, and then they left for other parts of he Galaxy, their fate is unknown.

There are however other cylons in this system that never came to this revelation, as far as they know the war against humans continues, they are in parts and pieces, most of them casualities in the war against the humans, there is all sorts of junk floating through out this system, some of that junk is pieces and parts of cylons left over from the last two wars with the humans, those if put together and reactivated, could pose a threat.

To block light from the four stars, they need be no thicker than a solar sail, and they can be placed any arbitrary distance from those stars. The Cylons evolved considerably since they last left the humans on Earth, the developed nanotechnology for instance, and they evolved into something so advanced, they would be unrecognizable to humans today, they could do a lot of things they couldn't even dream of doing when they were still fighting the humans. Establishing this system wide cloak was their last service to God in recompense for their prior attempts to wipe out the humans, after they discharged their obligation, they felt it best if they moved on and let the humans develop on their own. The statlites completely surround all four stars, and they are waiting for that ripple in gravitational energy that indicates the arrival of a starship from Jump Space, if they detect that, they self destruct, that is all their nanotech devices turn to dust and gas, a very thin layer that quickly disperses under light pressure from the four stars within.

 

[Tenacious-Techhunter]

They need to be no thicker than a perfect solar sail... which doesn’t exist. There will always be stray gamma radiation leaking through your physical shields which will have the same energy signature as that which comes from a star. And, again, no matter how thin they are, they each have to be larger than the star itself... and there needs to be one for every adjacent star from which that star could conceivably be perceived.

That’s a whole lot of pointless right there. Try something that makes sense.

It doesn't have to block all the radiation, just disguise it to look like something else, in this case a planetary nebula.

Such as this one for instance, the light of the stars is spread out to make it look like a planetary nebula.

The whole thing could be built at orbit 18 so it would surround all 4 stars. Seems like a lot of work? They are basically Von Neumann machines, they build enough copies of themselves out of surrounding material, and they had thousands of years to do it.

 

[Tom Kalbfus]

I am open to alternative suggestions, hiding the entire system and then revealing it is just one idea. A system with 12 garden worlds is rather unique, its existence would affect the geopolitical situation of any subsector its placed in, its hard to imagine this system as a backwater if it was known about for a long period of time, however if it is at the very edge of known space, pirates are unlikely to put a base there, there need a base that is close enough to civilization so they can conduct their piracy. Pirates aren't Daniel Boone or Davy Crockett, they like luxury and convenience just like everyone else, they like to steal those things! Being out in the wilderness where their is no one to steal from is not their "cup of tea!"

 

[Tenacious-Techhunter]

The light coming from the star would still have spectrum lines that blatantly identify it as a star undergoing multi-stage fusion rather than merely some glowing hydrogen gas.

Rather than rely on lack of detection, make it about accessibility. Make it so that the system can only be reached through some multi-jump J-3 path through apparently empty space, except that there are some hidden fuel resources on those routes (extrasolar bodies with fuel to crack).

You mean like put it in a rift?

Here is part of the Rift, the Empty Void subsector, officially it has only one star system, there is a Naval Base on Lasher, a planet with a population of 600, all of them Navy, this system is a Navy supply depot, there is a fueling station, where navy ships refuel, and also a civilian starport, Class B where refined fuel is also available, the Starport is in orbit around Lasher, very few people spend much time on the planet's surface due to its insidious atmosphere, but this is where the fuel is mined, brought up to the space station, and then refined, primarily for the Navy Base, but the surplus is refined and sold for a profit, the Navy contractor is running a fueling operation on the side in addition to supplying for the Navy. There is a small shipyard capable of constructing non-starships of up to 800 tons, and there is a repair facility as well.

If you count the hexes, you will see that Cyrannus is a Jump-6 away, very few starships are capable of making a jump-6, but he Navy crew manning the base have recently made a discovery of a quadruple star system deep within the rift, it was discovered by a Navy crewman, who was also an amateur astronomer in his spare time. After measuring the trigonometric parallax, he determined that the star system was within the rift and about 6 parsecs away.

 

[Tenacious-Techhunter]

The quadruple star system would be pretty obvious from even further away. From that range, they can probably detect planets by using techniques evolved from planet hunting methods used today. But yeah; some undetected rock with fuel on it at one of the Jump-3 points in-between would make things work out.

The pirates know it, the Navy does not!
The pirates operate through Rill

This is also a Jump-6 away from Cyrannus, but in the adjacent subsector to the right of the Empty Void. 60% of the population of this planet is Chirpers, tech level is External Combustion, basically steam power. A typical method of personal transportation is on horse back or a horse drawn carriage, aside from the steam locomotive, and steamship on the water. The industrial pattern is similar to the late 19th century Earth, sometime around the 1870s. One clue is horses aren't native to this planet, some humans have brought them in from another location (That would be Caprica) The horses appear wild and needed to be broken in, but have proved to be quite useful to the people on this planet. The Pirates know of two dwarf planets (Size 1) that can get a ship there in 2 Jump-2s, How they came by this information is a mystery.

 

[Rikki Tikki Traveller]

The rift could be empty, or it could be a cold hydrogen cloud. A star system buried within a gas cloud would not be detectable. There ARE gas clouds that are dozens of parsecs across, the spiral arms are filled with them. No need for any artificial masking, just a lot of dust.

ALSO, that would mean that the Cyrranus system would have VERY FEW if any visible stars... so without a lot of stars in the sky, why would they look for other worlds - they are unaware of how big the outside universe really is until contact is made somehow. Maybe they can see a couple dozen stars, so they know there are other systems, but who cares? THEN they flee the Cylon tyranny and jump to one of these distant stars, which is near the edge of the nebula and suddenly they see the galaxy for the first time - A Sky Full of Stars...

As I said before the current inhabitants of the Cyrannus system are primitive, to them the stars are just lights in the sky, and there are three other stars that are easily visible to them Helios Beta, Gamma, and Delta for the Capricans. The Pirates on the other hand are interlopers, they bring their own starships, and have basically found a treasure house to plunder. They can't eat gold of course, so they have to sell the Caprican gold somewhere for credits. They have also brought over some shaggy feral horses over to Rill, Genetic analysis traces those horses to a species that became extinct in North America at around 11,500 BC, they look like normal shaggy ponies, but a genetic analysis reveals this. The Cylons have been gone from this system for a long time, except for the parts and pieces of them that the pirates may find. I think the discovery of the Cyrannus System could seriously change the balance of power in the Empty void. the pirates could try to develop the system using the gold plundered from the Caprican vaults under Caprica City. The thing about gold is it does not corrode, it has no moving parts or electronics and can easily last 155,000 years, the geological changes to the planet, and continental drift have been relatively insignificant over that time. Basically there are a lot of primitive stone aged tribesmen and the Pirates, and except for Gemenon, and those three other stars seen in the sky, this setting replicates Earth in the Pleistocene, there are woolly mammoths, saber-toothed tigers, giant sloths and other prehistoric creatures from that time period. the pirates have however introduced change. For instance they have employed the stone aged tribes men in their various endeavors, some of them have learned to speak read and write, more advanced weaponry, such as bows and arrows have made their way from tribe to tribe, and of course stolen pirate's laser pistols upon occasion.

This is the map, as you can see, there are analogs for every continent on Earth except for Australia. the Continent Caprica City is on is an analog for North America, it is on the eastern coast of that continent. the Cylons, when they were here have noticed this similarity, so they planted North American Earth life over here, as it existed about 155,000 years ago. The evolutionary changes that occurred on Caprica were not much, and the humans here have not developed civilization, until after the arrival of the Pirates, in some places the local tech level has been increased to 1, there is some iron smithing going on, the pirates have found it necessary to teach them some things in order to make use of their labor.

I think you are neglecting the definition of the word “Obvious” here. The Navy will certainly know that there is both a quadruple star system, and a bunch of planets there. You have to make it an inconvenience for them to consider exploring the place. Probably a function of orders and refueling. Maybe their ships are too big to survive on whatever crackable hydrogen the Pirates found as a stepping stone to the planet... or maybe their ships are just too big to make the necessary jumps. At which point, they probably called upon the IISS, which is how the players might have gotten this job.

That doesn’t really fix the gamma radiation, though, or the neutron radiation.

I think as far as the Navy is concerned, they have a base to run and only 600 people to run it, the entire population of the planet is Navy Personel, some of them when off duty also run the Starport. There is no government or law level there because it is all navy, they pretty much all live on the space station/navy base/starport, a few make excusions to the planet's surface, but it is a pretty nasty planet, it damages vaccsuits so they don't go down their often. Some one of the base personel discovered the quadruple star system by accident, they new it was there for a while, and then determined its range, he previously thought it was a lot further away. Fortunately a new fighter pilot, a woman named "Kara Thrace" took the information to the nearest scout base, and from there the PCs were contacted about a possible mission. When the navy crewman did a background check on the fighter pilot, there was no record of her having been in the Navy or having been assigned to that base.

Finding rogue planets in interstellar space is a lot harder than finding planets orbiting another star, the pirates had help from a "fallen angel", or the pirate leader had to be precise. In other words their are higher powers in the Universe, one of them chose to intervene for the pirates, whatever his agenda might be, who could say. There are certain "angels" or "ghosts" that have been known to haunt the Cyrranus system from time to time, usually they appear to one particular person, and no one else sees them, usually they are dismissed by other people as hallucinations, but whatever it was that contacted that pirate leader, he knew something, such as the locations of those two rogue planets for refueling stops. Some other pirates have had from time to time a vision of a blonde lady who called herself "Six", sometimes her agenda goes against the other one she called "the fallen one!" Of course the other pirates can't prove a thing, they see no one. Some theorize that it must be one of the Ancients taken human form, others dismiss it as madness.

Look what I found! Would anyone like to convert this to Mongoose Traveller? I don't know if there are rules for it.

The 15.5 Megaton Battlestar Galactica

--------------------------------------------------------------------------------

I have the Battlestar Galactica Role Playing Game, but I just couldn't resist converting it to Traveller T20. The first thing to note, is that this Battlestar is much more futuristic than the one from the New Television Series and RPG, part of this could be helped as T20 doesn't have stats for railguns, so I substituted Pulse Lasers instead for the point defense system. It turns out My Battlestar Galactica has 7,750 pulse lasers all over its outer hull, this is for shooting down those Cylon Raiders which I'll detail later. I've looked at the dimensions for the Battlestar Galactica from the RPG: 4,593 * 1,725 * 739 feet. I've divided each dimension by three multiplied them together to get cubic meters and divided that number by 14 to get displacement tons and I rounded up to get the figure of 15.5 Megatons of displacement, this is a huge ship. For the Viper, I just threw in the Standard 15-ton Fighter from the Traveller Handbook, unaltered. Substituting for the Raptors, I threw in the Imperial Scout/Courier which serves the same function in the Traveller Universe. The Galactica has two landing bays, each one has approximately 550,000.0 tons of displacement and their are two. The stats for the Galactica in the RPG lists 80 Vipers for its one functional landing bay, the other one was converted to a museum. For this Traveller scenario, I assume that both landing bays are functional and so I have doubled the number of fighters to 160. (80 per landing bay) Each landing bay also carries 12 scout/couriers and 12 shuttles for a total of 24 and 24 on both combined. The landing bays also has a launch tube for every fighter and hangar space for all spacecraft with plenty of room to spare.

The Galactica also hold room for 10,500 people, so I have included 6,000 staterooms.

Turns out the landing bays are quite cavernous, plenty of spare room. That's the way they look in the TV series as well. I suppose alot of that space is so individual spaceships can maneuver around inside the landing bays (which are enclosed)
When the landing bay doors are closed, the entire landing bay can be pressurized and crew can work on the individual spaceships in a shirt sleeve environment. The hangar space is located below deck which are accessible by cargo elevators which can lower entire spaceships to their below deck hangar space. The landing deck is also large enough to receive some smaller capital ships such as Colonial One, although, it would tend to occupy the landing deck and prevent further spaceships from landing there. The launch tubes are below deck and vipers can still be launched, they just can't land until the landing deck space is cleared.

So what do you think of my work here?
I suppose the price in Cubits (which are equivalent to credits) is a rather academic exercise. No one in any campaign is going to buy a Battlestar, and in this campaign there are only two in existance. (Galactica and Pegasus.)

Well its descriptive anyway, this is the sort of Battlestar the pirates might wish to build, it uses standard shuttles, Scout/Couriers, and fighters, they would need the Cylons to build it, perhaps there is an old warhulk drifting around in the system that wasn't too badly damaged by the Cylon attack, they would then have to retrofit it with 3rd Imperium subordinate craft that they would buy second hand from various planetary navies, they would have to sell a lot of gold, in a number of different planetary systems. This would raise a lot of "red flags" with Imperial Intelligence I think.
