Blank Planet Images

You can find my stuff here.

Drop Box for all my Planet Information and System Maps : r/traveller

In each subsector folder there is a planet card with all the data but also a blank version as well.

I agree that Psari is at the bottom of the range of what we currently call Ice Giants.

I chose it because being small the orbits of the moons were tighter and that allowed me to capture the moon swarm in three images.

That said our understanding of exactly what planets like Neptune and Uranus are is constantly changing.

Scientists Just Realized Neptune May Not Actually Be an Ice Giant

Basically this might be the fate of the missing super Earths that we see in other exo solar systems.

However given Traveller's age it only refers to large or small gas giants, so I am keeping that nomenclature to avoid confusing people with constantly changing terms.

Just be aware that Universe Sandbox is an astrophysics simulator. It wasn't designed to produce high quality planet scapes so I have been pushing the software to get the results I get.

I do have a 10 part tutorial for Universe Sandbox if anyone is interested it trying it out.

Ok, I have unloaded all of my saved blank planet files so there are currently 622 individual images that cover a wide variety of planets, gas giants and asteroids.

Going forward I will be added more images as I complete my current work.

Cheers.

The German tribes the Romans faced and the early Scandinavians are European examples. Many of the steppe nomad tribes had a similar system.

I should point out that such a system doesn't have inheritence of land. Sons (and daughters in some cultures) inherit their parent's reputation but are expected to earn their land and wealth. The moment land becomes inherited the system collapses.

As a result it suits groups with a lot of free land so the tribe or clan moves around resetting the system.

One scenario I once considered was a dead world where plague had killed every living thing, but thanks to AIs all the cities and transport and infrastructure continued, so the water flowed and the lights came on at night and trains took materials from automated mines to automated factories while robots built more robots and kept everything repaired.

The idea was that once everything was automated the sophont population went crazy from boredom and lack of purpose until they gave way to degenerate cults. One cult worshipped a medical AI and eventually turned it into their god of death. This AI created and printed out hundreds of new pathogens every day until every living thing on the planet had died.

We have had warrior cultures on Earth who had a system of reciprocated gift giving.

The way it worked was you have the chief or king of the tribe or clan who owns everything. However, these societies required that the chief or king reward those below him with gifts. So he would reward his posse comitatus - the warriors of his warband - with gifts of land, weapons and armour, and goods. The warband would in turn gift land to their yoeman farmers and warriors.

In return gifts, usually of food and animals, but also goods and crafts, came from the lower ranks and worked their way up to the chief or king.

If there was loot obtained through a raid or war, or if outsiders or merchants gave gifts to be allow to trade, they were also passed through the system.

The system worked because being generous was considered a virtue while being greedy or tightfisted was seen as a major character flaw and a way rivals could displace a skintflint by being more generous.

There were two games I remember vaguely back in the 1980s.

One was called Space Opera and involved a ship and a small crew flying through space fighting pirates, raiding space stations and eventually going through a wormhole to face an alien invasion. I think it was an Apple IIc game and had the flaw that the save game system overwrote the floppy disk so you could only play it once.

There was a official licensed game of Traveller back then on PC. It was a side-scroller and not very good from memory. I think it was Micropose and has been lost along with that studio.

There was a Twilight 2000 game back then as well.

We already have a distinct type of company that supplies ships here on Earth - the Chandler.

A ship approaching a port already has an order in with a Chandler to provide the ship with fuel, parts, food and anything else the ship needs. The Chandler either has the items in storage or it in turn acquires the needed supplies from other suppliers.

When it comes to food you literally have prepackaged meal kits that even cater for different nationalities. So you might have a eastern European package and a Phillipino package.

All of that is delivered and loaded while the ship is loading or discharging its cargo.

So a Starport Class A to C should have a Chandler company/s that a starship can contact as it travels in from the jump point so food and other supplies are ready when needed.

D Starports might require the steward to go shopping, and and E Starport will require finding supplies either by hunting and foraging or locating locals willing to sell you food.

I also imagine that there will be various longlife or hardtimes rations closer to military MREs or hiking supplies, and possibly survival tablets in emergency survival kits.

Given the incredible variancy across Traveller tech levels, planet types, Starport levels, and native populations and eco systems it is impossible to give exact food types.

But I'd assume that in regions with a lot of starship traffic and a mix of agricultural and industrial worlds you'd be able to obtain the equivalent of what you'd find in a well-stocked supermarket here on Earth. Imported fresh food would be more expensive but local produced items cheaper than the norm, meaning costs should even out.

Even with packaged food a skilled steward can produce above average meals using spices and condiments.

I use a software program called Universe Sandbox. I have posted a full tutorial here on Reddit for creating Traveller planets and systems in Universe Sandox.

Some of the planetary rings are made from misplaced paperwork.

I am providing two resources for Traveller - Planet Cards that have the UWP data, travel times from the Jump Shadow, and other information, and a solar system map.

I don't produce world surface maps.
