Traveller

Wow...it's been a while since I've posted here.

Let's get back to speaking or talking (Ha!) about role playing games. One of my favorite games is
one of the first sci-fi role playing games Traveller. I still have my old Traveller Book. In Traveller, the referee can run a variety of sci-fi campgains, from military to trading, even espionage or exploration. I think this is one of the benefits of the game. It's rules allow for different styles of games. The referee can make their own setting or use the established one. It's been around since 1977. The name Traveller refers to the game but it has a variety of rules. From GURPS to Mongoose Traveller, which itself is based on the old Classic Traveller rules. The creator Marc Miller currently publishes a version called Traveller 5 abbreviated as T5. It's called Traveller 5, because it's the fifth incarnation of the rule set that Miller has been involved with.

One of the things that Traveller fans have done over the years is called the Traveller Landgrab. It's where fans take one of the published worlds for the system and put their own spin on the world. There's hundreds of worlds most of them found at the great site, Traveller Map. The site that used to house my 2006 Landgrab entry is down but it can still be found: here I wanted to repost it here. Orginally I posted it to the Traveller Mailing List. I picked the world Lahti, which was published in the book Gateway to Destiny, which is one of my favorite Traveller Books. Anyways, here's my old entry:

HISTORY - Solomani colonists settled Lahti during the ending years of the

Rule of Man. Lahti retained starflight during the Long Night and sent ships

to surrounding worlds. Those worlds however remained independent as the

years went by. Hiver Federation contacts in the early years of the distant

Third Imperium helped keep Lahti?s technology level at the highest for this

part of the subsector. A few Vilani settlers traveled to the planet in later

years as word of the governmental view traveled across known space. Now the

planet is an active trading partner in the subsector. The planet exports

varying types of products.

GOVERNMENT - Lahti is ruled by the Society for a Rational Spirit. The

government strictly prohibits other organized religions. All persons working

in large organizations such as corporations and the military are expected to

be practicing members. The government sponsors a sizable Naval and marine

force. A highport Naval base orbits near the highport area of the starport.

There is also a naval base on the planet Lahti I Epsilon. The navy has three

light cruisers of around 17,000 tons of Solomani design. The other ships are

patrol cruisers, fighters, close escorts and SDB?s. The government has

extremely poor relations with the Droyne in the subsector since the Droyne

failed to respond to a Lahtian merchant?s ship?s distress call two years

ago.

ATOMSPEHERE - The atmosphere is tainted by thick smog and filter masks must

be worn outside. Years of uncontrolled burning of hydrocarbons led to the

thick smog.

POPULATION - The population lives in extended urban areas and 2 orbital

cities. The capital city of the planet is Sego with a population of

500,000,000. Several of the other major cities are Logan, Nice, Turin and

Newago. Coastal communities support the capture of fish and the mountain

ranges are the locations of ore mines including uranium and magnesium and

coalmines.

CULTURE - Pregnant women are not allowed to eat meat or fish products and

Women who commit crimes are forced to have numbers tattooed on their right

forearms and the data entered into a planetary database. These women are

forbidden to enter the military or work in large corporations.

Despite the overall conservative culture of Lahti, the planet trades in

substantial portions with the Hiver worlds to trailing. The Hive Federation

has a trade compound on the capital city, Sego.

Adventure seeds: The PC's are asked to escort several large Lahtian merchant

ships a few parasecs to Hiver space and return with a cargo load of Hiver

robots.

The Church of Stellar Divinity has hired the PC?s to free by any means

necessary several members of their faith being held in Lahtian prison.

The PC?s are asked to deliver a load of cargo to a mining colony on a gas

giant moon orbiting the secondary star. What could possibility go wrong??
