One thing I always want to see when I play in a game or run a game is a single place that I can say is home for the characters. Somewhere that the players can set down some roots and have a home, have some regular contacts they meet with, and a chance to shape their own environment. To that end, I was wondering if I can interest everyone in building a habitat that can be used for exactly this purpose.
I suggest we build Extropia. Sunward won't have it included and I don't want to wait until the Outer Rim book. Extropia would be perfect for this kind of project based on the nature of the habitat. I might have a great idea for an NPC that runs a security company, but someone else might too. In Extropia, both could and should exist as competition for each other. The habitat is as large as some of the largest cities on Earth today so has tons of room for our creations. Heck, depending on how we approach this, we might be able to just slip in everything we design into whatever they come out with for Extropia in the Outer Rim book!
I've been thinking a little bit about NPC design and it seems to me a standardized statblock will have to be worked out. Perhaps filled out PDF character sheets? It'd certainly cover everything but I wonder if it might be too much information for ease of game play. I was toying with the idea of each NPC having a Solarchive entry that players could search for when looking up the NPCS. Also, I really like the idea of including an entry on each character for "Their price". Extropia is all about buying, selling, and contracts, so this could be what they want most, something they'd be willing to do just about anything to get.
Anyone want in on this project?

Building Extropia

- The remaining asteroid is counterspun (not necessarily to the same speed, it can be heavier) and the Cole bubble is connected to it with a rigid axis. As Psyfer points out, this requires some impressive engineering: there will be significant torques on the axis and it needs to connect two counterrotating objects. It also provides a nice transport system.
- The Cole bubble is not connected to the asteroid but spun along its long axis. Leaving aside the minor adjustments needed to keep it spinning along that axis, its angular momentum vector will need to make a 360 rotation every six hours as it rotates around the total centre of mass. This will lead to tumbling: the habitat will not stay oriented in the same direction relative to the asteroid. Making Extropia torus-shaped or disk-like just fixes the instability of the long axis, the tumbling is due to having two different rotations combined. On the plus side, this does not require any complicated engineering and I think the tumbling will not have a major effect on the internal pseudogravity (the six hour rotation is pretty slow; I get a centripetal force of about ~0.0008 G at the far end). On the minus side it will be trickier to go from the asteroid to the bubble, and the light reflection solution gets messy.
- Extropia is surrounded by counter-rotating weights (or high gravity habitats, industries, reserve stores or whatnots) linked to it by cables and attached to belts around its circumference. This keeps the total angular momentum to zero, and the cylinder will nicely point at Nysa without doing any tumbling. As it rotates there are various torques on the rotating bands, but they can be distributed over pretty large areas. On the plus side this keeps the asteroid and Cole bubble plus allows some nice connections along the long axis. These weights could actually be used as flywheels for massive energy storage. On the minus side we get some extra infrastructure that could potentially (but very unlikely) go wrong.
- Extropia could be a bolo habitat rather than a true Cole bubble: take the converted half of Nysa and turn it into a cylindrical box connected to Nysa through a bundle of cables. The centrifugal force provides gravity when the distance is right, it is easy to engineer and one could put a bus/elevator on the cabling. But this limits the area quite a lot and contradicts the book.
- Turn part of Nysa into a Cole bubble but not all of it, rotate the whole shebang along the long axis. This is pretty unappealing but makes the low to microgravity beehive an integral part of the habitat.
My own choice would likely be option 2, separate rotation. Yes, the habitat will be tumbling but that is just a problem for navigators (who are all enhanced anyway; to an AGI who has grown up in a symplectic manifold or a space dolphin it is all obvious). From the inside everything is fine, especially since the optics anyway will have to massage the sunlight to earth-like intensity and colour. Option 3 is not bad either, and outsiders might well overlook what those weird spars and cables are for. Of course, a critic could say that we could just as well decide that it is either a beehive or a bubble, but the extropian thing to do is to have one's cake, eat it, replicate it and upload it!+1 r-Rep , +1 @-rep
