Banasdan (How would you World Build it?)

[ColinD]

My campaign started on Banasdan and the Travellers are headed to the Core Worlds and Capital itself, which is why I'm excited about Singularity! When I made Banasdan I utilized Solomani Front . I ask those World Builders out there how would you handle the system and more specifically the planet? I followed the World Builder's Handbook and put Banasdan in a circumbinary orbit around the two suns. I also put it in the baseline orbit within the habitable zone.

I followed the description on wiki.travellerrpg and decided to make it, "barely habitable, so the vast majority of the planet’s population huddles in sealed arcologies or underground cities." (direct quote). But being a 50 billion population planet and the Subsector Capital it needs the trade from the surrounding systems to stay alive.

Would any of you make the planet tidal locked or slow rotation? I'm interested in your ideas.

You could have the main arcologies supplemented by a few lesser important orbital cities. How you implement an arcology or orbital city is left to the imagination , there are currently no rules or guidelines or ref briefing available, AFAIK.

"Additional Cities: Any unallocated urban population, or total urban population minus major city population, reflects the residency of medium and small-sized cities. No medium sized cities should be larger than 1% of the major city population and small cities should be no larger than 0.1% of the major city population but the Referee is otherwise free to allocate the remaining urban population as desired." WBH, pg 154

Thanks. That is a great idea!

Hmm for a population of 50,000,000
Large arcologies - 10,000,000 x 5000 (Earth has 80 cities of this size)
Medium arcologies - 1,000,000 x50,000 (Earth has 500 cities of this size)
Small arcologies - 100,000 x500,000 (Earth has 4000 cities of this size)

Imagine 5000 arcologies, each of them 10 million people! The World Builder's Handbook states,

"In some arcologies, the population density may be in the millions per square kilometre and such giant edifices often measure their population density in people per cubic kilometre instead."

If I made 1 million sophonts per cubic kilometer that would be 10 cubic kilometers.

According to Wikipedia:
Mumbai's population of 13 plus million people over 603 square kilometers and has a population density of 22,937!
Manila has a population of 1.7 million people over 38 square miles and a population density of 43,079.
Kowloon Walled City "had a population density of approximately 1,255,000 inhabitants per square kilometre (3,250,000/sq mi) in 1987"!

So these could be like the Kowloon Walled City.

Thanks! Gives me lots of ideas.

It’s not at all like Kowloon, since that figure was per square kilometre, and the arcology density you suggest for yourself is per cubic kilometre. That’s probably one to two hundred times less dense (not 1000 times less dense because Kowloon was many stories high in most places, although streets and alleyways make it more complex to calculate).

Edit: including machine and service spaces, probably much like Mumbai..

The station section of High Guard allows you to make habitats, and the POD campaign has rules for space components in buildings with a discount for them not being mobile.

Average density.

Good point! If I kept the arcologies flat they would be like the Walled City of Kowloon, but if I built up it would be less dense. JTAS 15 has an article by Ben King called "Under the Domes" that shows how a domed city on Ralhe operates.

The World Tamer's Handbook, page 33,has a chart showing population density in housing by TL.

0.05km2 per million m3 at TL-15

That is 800,000 people per square kilometer if you assume an average of 25m2 per person, as they do in the book.

I'll look that up!

I need to add that I really utilized the Trade Codes in Solomani Front for the adventure. Hi Ht Po (High Population, High Tech, Poor) and the description from the Travellerrpg "This world is always on the edge of revolution as the common citizen struggles under extremely low wages. Much dissent is present." My home game who were in the adventure and conventioneers (ran it at TravellerCon the first time I attended) enjoyed the Startown around the Downport.

Oh man I had a campaign back in 1983 or so that started on Banasdan. Lots of great stuff in the vicinity. Enjoy.

I looked over High Guard and that was good advice. I don't have POD. Any chance you remember where in POD are the rules for space components in buildings? I might go and buy it.

 

[Condottiere]

You can build high, into the sky.

You can build down, into the ground.

You could build it in line, resting supine.

The rules you are looking for are poorly written in PoD. Geir will basically be rewriting them in the Vehicle Handbook rewrite/update.

That is true.
In the interim, you could use 10K per ton for structure above ground and 2k below ground, with a 75% discount on starship components.
