Ringworld (CT type)

Leenitakot in the Hinterlands

The Ancients also created a ringworld in the Leenitakot system of the Hinterworlds. Even their approach to building a ringworld puzzles the experts. It circles a dim MI V star at less than 30 million kilometers. The ringworld is a narrow band less than 100,000 kilometers wide, and the construction looks unfinished, without soils, atmosphere, or any provision for life to live on its inner surface. And even so, this small ringworld has an inner surface area equal to 25,000 Terras.

Not terribly useful. Nor interesting other than as color.

not life as we know it, anyway. maybe it's a home for ghosts. visit it, bring back a few ....

That's how I felt too, but the whole "The Ringworld is Unstable!" argument suggests something is active there to keep it properly spaced.

I was wondering if anyone found something to do with the ring game wise.

I suppose it could be mined for super-alloys. Provided it can be mined at all, that is.

Well, the thing is that the ringworld's fine for thousands of years, maybe even tens of thousands. And with both induction current and gravitics, the ringworld can easily be self correcting in ways that Niven's could not (since Niven doesn't use gravitics in his universe). But given that it still needs scrith to work structurally...

If I were going to use it, it's not an incomplete ringworld. It's a star jumper. It takes a few decades to charge, then jumps the star. They'd land on it, just in time to wind up in the destination pocket universe. But the controlling droyne had to go hide for a few dozen centuries because his grandfather was pissed off at him. He gets back, sends the commands, and poof - the whole inner system enters Jump Space.
 
Just my two Imperial credit's worth but I suspect The Ancients did very little on a whim and any unfinished projects are just part and parcel of a much larger as-yet understood master plan.

Sooooo... its a huge flat bare metal ribbon 100,000 kilometers wide and 30 million time Pi Kilometers long? With high walls on each edge? That is a huge chunk of real estate.

How much material is in system? Kuiper belt objects or cometary material, or really anything else in system? Sounds like a great 'fixer upper'.

Actually, 60 million x Π km long.

It depends on just how "incomplete" the ring actually is.

As Aramis pointed out, you would need some sort of "super-material" (like Larry Niven's Scrith) for construction of any part of the ring's primary structures. Neutronium might suffice, but even at TL15/16 I doubt the Imperium has the technology to produce such material in vast quantity (otherwise they would be using it for other applications - and that would be a setting-changing innovation).

If the actual ring structure and walls are complete, however, you might be able to do something with the interior surface as a long-term mutli-generational "terraforming" project (perhaps in a few "compartmentalized" areas).
 
0The ringworld is the first stage in pinching off the star into its own pocket universe to power a starship.

The fact that it is still stable 300,000 years after it was constructed suggests there is something maintaining it, probably residing in a small pocket universe of its own or hidden in jump space.

Now THAT'S an adventure! Just not a very long one.;)
 
You only need super-materials (scrith) if you're attempting to use spin gravity.

If instead you're using gravitics, it can spin at natural orbital velocity, with natural free-fall/microgravity, and gravitics for the local gravity. Or if sufficiently thick, its own gravitation.
 
I wouldn't know what to do with that thing as a referee.

Oh. I guess it could be a hunt for something important there. It wasn't finished, but there's something fantastic there. But it's impossible to find unless you have the exact coordinates and know how to make it visible.

Assume it's a TL27 construction (T5 p.509) somewhere in Orbit 1 (6 million km, plus or minus a million or so). At this stage, technical size doesn't matter. It's a stellar-scale object. I figure the solar system is cleared out, raw material to refine into scrith for construction.

I would think that the ringworld wasn't completed because the builders (ancients, presumably) were exterminated before they could complete it.


In my thinking, once you're above a certain tonnage (maybe 1,000,000 tons), or above a certain population (maybe 10,000), you've crossed over from a ship to an event, such as a world or installation, where measurements are no longer about tons. The Loeskalth Planetoid ship is in this category. Of course, so are jump-capable worlds that the ancients apparently had.

The MgT version of Secret of the Ancients retcons the Ancient war somewhat...

an artefact like this could be a trap, an intelligence test to find useful agents, or a shorter adventure than Twilight's Peak as you say =)

Is there ANYTHING MgT DOESN'T retcon? I'm serious, I really want to know. But maybe it shouldn't be posted lest Matt realize that he overlooked something...:rolleyes:
 
Oh ho! Really? Then I'm now twice as determined to stick with CT, and not support Mongoose. There's nothing worse than a lowdown, retconning...retconner.

That depends entirely on whether the stuff he retcons is good or bad. There's nothing worse than a publisher who regurgitates self-contradictory nonsense without fixing it. ;)

I suppose that strictly speaking I ought to be outraged by the fact that MgT retconned the old Secret of the Ancients, but I must confess that my outrage is somewhat reduced by the fact that the old SotA was essentially a bland and boring railroad trip to a vacation at Grandfather's Place.

Back to the ring. This thing could have multiple civilizations living on it and never know the others existed. (Lower tech)

Next time your PCs run afoul of the law, community service hauling dirt, at cost, for 6 months?:devil:
