How does a mainworld with size R exist in a system with no gas giants?

[Agrikk]

Vanguard Reaches:

Xylus              1731 DR00315-C   Lo Na Ni          530 Ac

(Pop multiplier of 5, three belts, no jovians)

In validating the data for my extended system search web app, I noticed that the only mainworld listed as a ring,Xylus, is a system with no gas giants.

Does this mean that Xylus is a ringworld created by the ancients? My google-fu turns up nothing about a ringworld in any of the campaign settings called Xylus. Is this just a discrepancy in the sector info about the planet? A fluke?


(sorry about the slow load times for the app. my DB still needs normalization)

probably the proto-planet had an erratic orbit that too close to it's sun and ripped apart by gravity

or

the proto-planet got hit by a BIG planetoid and they went kablooey --

Since no mainworld generation system I know of can yield an R-sized "world", it's either a mistake or a deliberate choice on the part of the setting designer. IMO a ringworld is so rare that there would be no standard character for it in the UWP lexicon. My solution would be to lump ringworlds, rosettes, Dyson spheres and anything else that's truly exotic together as "X" sized worlds with an accompanying explanation.

But that would produce a belt, not a ring, right?



Also, I didn't generate the world. It appeared in the Galaxy 2.4 .SEC files for Vanguard Reaches.

Agrikk,

That's simple. It Doesn't

You're using a notoriously broken data set for your app and the result is "Garbage In, Garbage Out".

Galaxy 2.4 uses the Genii/Sunbane data set which is broken in two fundamental ways.

First, the LBB:6 Scouts sysgen system was broken with regards to astonomical science when it was originally developed.

Second, the computer program which produced the Genii/Sunbane data set didn't implement the LBB:6 sysgen correctly.

So, you have a flawed sysgen being implemented by a flawed computer program with the result being Xylus.

No GG? No problem. It's around a "normal sized" planet. Someone used Advanced Generation, and ignored that rings are uninhabitable.

.

lol -- true -- but for system creation -- a belt is created iirc -- whilst a world itself has rings

Now -- a Ringworld -- that is like a Dyson sphere or other Ancient tech created wonders, so it depends on how you wanna "interpret the R. For me -- I would think of it as 3 asteroid Belts (which can have people) vrs rings (which cannot)

Wootles!

That's a bummer. I suppose I assumed that the data had been vetted by someone, somewhere.

Oh well. I suppose Xylus will orbit a otherworld, then.

Agrikk,

Robject, an active member here, began a project doing just that.

I don't know how far he got, but it would be well worth dropping him a PM on the subject.

Good luck with your app.

[Agrikk]

I will do so. Thanks!


As far as the app, have a look:

According to CT Book 6 (Scouts, p36) when generating a satellite a roll of exactly 0 for size is treated as R. Therefore in CT non gas giants _can_ have rings, at least if they are size 6 or less because satellite size is mainworld size minus 1d6. Since non gas giant planets will have an mean average of 1 satellite [roll 1d6-3] and one sixth of the satellites orbiting planets of sizes 1 to 6 will be rings therefore one-sixth of all planets in this size range will be ringed....

The real problem with the data is the presence of a population because rings have a population of 0 (op cit p37). Thus the data is indeed bad, but not for the reasons given so far.

Also - According to the original data on the Vanguard Reaches sector (Paranoia Press 1981)
hex 1731 (Old Colonies subsector 0101) doesn't even have a planet in it, but I believe that PP's version of the sector was decannonized by a GDW dot-map so I suppose that's a moot point.

Peter,

Hence, Trin's Veil...

Hmm... the Xylus UWP show's an inhabited ring... LBB:6 doesn't allow for inhabited rings... OP is told that the reason the data is bad is that "the computer program which produced the Genii/Sunbane data set didn't implement the LBB:6 sysgen correctly."...

So, why is that reason incorrect again?

According to the original data on the Vanguard Reaches sector (Paranoia Press 1981)...

De-canonized silliness. Do you really want matter transmitters, the Com-Sentient Alliance, a winged Human Minor Race and all the rest?
