zooming in with diaspora anabasis

One of the ways I design, as I’ve discussed before, it to create my objective from scratch and analyze the way I get there in order to find a way to mechanize it so you can do it too. We’re currently developing the sequel to DiasporaDiaspora Anabasis — and I am at a place where I need to do this again.

We have cluster creation and character creation pretty much solved now. But in developing my prep notes for a session of play I find I want to know more about each system. In the original we hand-waved this, but I’d really like maps showing the worlds in a system in order to make them more real, more huge, and to avoid the common pitfall of conflating world and system. Also, with the happy fame of The Expanse i think there is even more energy in the community for these stories, the stories that take place during travel inside a solar system. This also makes lower technologies as rich to spin yarns about as higher technologies. It opens up the scope of the game.

So let’s start with a map.

The Antoine system.

Before starting this map I have some information of course. From the core conceit of the game I have the slipknot, the point from which high technology vessels can jump to other systems in the cluster. That’s the shape above the star.

The cluster!

From the cluster generation I have statistics for the system. I know that it’s a rich system, with multiple inhabitable worlds, one of which is a garden planet. A place naturally lush with life and air and water. I also know that the inhabitants support an industry capable of using the slipknot.


From character generation I have more information. I know that there are prison worlds because more than one character escaped from prison here. I know that the system protects its technology, refusing to give it to other systems. I know that it is deeply colonial, seeing itself as the patron and protector of the other systems which it believes cannot survive on their own due to their lesser industries and at the same time believes cannot be trusted to wield the power of that technology themselves. It’s a familiar place, no?

This, of course, is why games must always be political: any story worth telling is political. Humans talking about things make politics. Humans imagining things make politics. But I digress.

So if you hoped I would talk now about the new mechanism for system generation you’re going to be disappointed: I have no idea just yet. I drew the sun and a line and put some worlds on it. One is the garden world of Antoine and there’s a gas giant because systems probably have gas giants. And then I wanted some distinction and some wonder.

Antoine is a garden world and the original colony in the system. It is has vast burgeoning oceans and cities that reach into the sky. Its industry, pollution, and crime are exported to other worlds. While there are hints of revolution here, it is quickly exported to the Beregons or, worse, Lens. Hush is its moon which houses several habitats despite being airless.

Here’s a pivot point of course: I want wonder, so that needs to get baked in. In this system I put the prison worlds of Beregon in. Two planets orbiting each other closely as they orbit the sun. This is well north of improbable as a natural event and that’s a good vein to mine for wonder: how the hell did that happen? That’s a point to mechanize. Perhaps a set of oracles for wonderous improbable things.

Beregon alpha and beta are mutually orbiting planetoids. They have pressure but limited air and resources sufficient to create and sustain habitation. They are primarily inhabited by industry, work forces, and prisons. The configuration of these two worlds is not explained by astrophysics: they are probably an artificial construction though there is no evidence of a prior culture here.

I also decided that with this level of technology large space stations would be viable. So I put some in. And that there would be a station to defend and manage the slipknot. And there’s another point for mechanization: a list of things that are normal at each technology. Still wonderous as technology advances, but normal for the technology. Certainly an orbital that houses half a billion people is wonderous to us, however mundane it is for the locals.

Arkady is a radioactive wasteland many times its expected density as it is composed mostly of heavy metals. It is hypothesized that it was ejected from a nearby super-super-nova and captured in the Arkady system. A massive industrial orbital, Lens, is used as a shielded base of operations for mining and it houses half a billion miners and administrators. In high orbit is an electromagnetic deceleration tunnel for pushing unpowered or low fuel masses to inner orbits. It is predominantly used for mining shipments to inner worlds.

Elminster station is the slipknot station for the system. It is highly militarized and provides all layover, maintenance, and r-mass functions for both civilian and military spacecraft. It does not police slipknot transitions unless the ship lacks an approved and up-to-date beacon.

So what I’m leveraging here is the idea that many things wonderous would be normal at high levels of technology and that that normalcy is itself wonderous. Playing in a world where a wonder is mundane creates an emotion in the player that’s fun even if it’s not an emotion in the character. And yet there is still room for wonder in the characters as well by imagining technology or celestial happenstance that would be baffling and awe-inspiring to the characters. Two wonders are available to me!

I also know from the cluster and character generation that there are many inhabited worlds here. One thing we might want is to have habitable moons of the gas giant. Which means we need to wonder why they are there? So:

Corazon is a hot jupiter gas giant, swirling with radioactive gases, a failed star. It has more than seventy moons but only four are of interest. Matchbox is an ice ball well within the region of Corazon’s gravity and radiation to cause intense activity and liquid water volcanoes. Peril is just a rock, albeit a very battered one, and holds not substantial colonies. Ash is a nearly human-normal temperature and holds enough pressure to make colonization cost effective. It houses several breakaway religious sects and political rebels and maintains a navy sufficient to dissuade Antoine from changing that balance of power. Oka is similar but has a somewhat harsher, colder environment and much richer mineral resources.

So here’s another point to mechanize: why do people live where it’s difficult to live? Perhaps a list of possible reasons, another set of oracles, to choose from or get random information from. Because there is always the fact of the astrography and then the rationale for being any place in it. Or not being there.

Buzzard is a long way away and under explored. Even with current technology at Antoine, it would take more than a year to travel there and there is no reason to believe it’s worth doing.

And then I sprinkled it with another idea I had not inspired by anything in either the rules text or the generation text: I figured that if you were at the point where you were heavily exploiting an entire solar system, you’d also be thinking about ways to make that cheaper. So I added the Decels — vast electromagnetic railgun structures for moving in and out of heavy traffic but distant orbits. Because sometimes you’re not in a hurry, you just want to constantly move a lot of material. And since one of the worlds was lacking distinction, I put it there.

Lepzig is a rocky and metallic frozen world with substantial resources and a naval installation intended to keep a reserve force available to counter Ash or Oka aggression. It is generally considered to be punishment duty. Its two moons, Shepherd and Wallace, are also heavily militarized but they have no resources to speak of and are better considered bases than habitations. Regular traffic from Leipzig is required for them to be maintained. In high orbit is an electromagnetic deceleration tunnel for pushing unpowered or low fuel masses to inner orbits.

So now all that’s left is to mechanize this in a way that’s fun and reproducible, so you can get at least what I get when I play.


Thanks to patrons for the pressure and the energy.
