Adventures in RW & KS

Dennis Antinori, The Longshot Cockpit ©2003.  To travel through Human Space in the Long Shot (the Quantum 2 ship that Louis Wu and his Motley Crew flew to Ringworld in) then go here

Known Space in late 29th Century is about 80 light years in diameter with 10,000 stars.  This space also includes Human Space as well as neighbouring Alien civilisations.  Most of these star systems have never been visited by humans with Human Space itself being about 40 light years in diameter, with 524 stars in 357 systems.  This irregularly shaped bubble remains unsettled and inadequately mapped even after centuries of exploration, colonisation and military expansion.  There are 30 billion humans alive, of which 10 billion live on the dozen colonies, with Silvereyes being the furthest colony from Earth 21.3 light years).

The scope for adventure in this huge area of space is ripe.  A number of remote bases and settlements exist out in the edges of Human Space.  Less than 1% of Humanity has travelled from the heavily populated worlds

c 15 Billion Years Ago
Creation of the Universe. [Ya gotta start somewhere!]

c 10 Billion Years Ago
Galaxies form.

9 Billion Years Ago
The "Outsiders" watch as planet-based sapients begin to develop. (MKW7 "A Darker Geometry")

1.5 Billion Years Ago
The Thrint, later known as the "Slavers", rule the Galaxy. [This is described as anywhere from 1.5 to 3 Billion years ago].

The crypto-Ptavv Guerdoth's Pruntaquilan Balladeer Coquaturia is hidden in a stasis box. (MKW5 "Hey Diddle Diddle")

In the last decades before the end of their rule, a thrint named Plorn's tnuctip slaves produce antigravity, ruining the need for Stage Trees to launch material, and precipitating a major economic crash. ("World of Ptavvs", "A Relic of Empire")

At this point, Kzanol experiences a failure of his ship, which he abandons. He aims it at the eighth world of F124, and places himself in stasis. His ship slams into a moon orbiting the eighth world, tearing the moon from its orbit and forming the planet later called Pluto. Kzanol slams into the algae-covered sea of F124 - III, later known as Earth. ("World of Ptavvs")

Before Kzanol actually impacts onto Earth, the Thrint Empire is engulfed in a civil war that will last for a century. This long revolt is led by the Tnuctipun, using their weapons of Sunflowers, and their Bandersnatchi / Whitefood spies. This war quickly involves all known species in the Galaxy, presumably excepting the Outsiders. ("World of Ptavvs", "The Soft Weapon")

As it becomes clear that the war is lost, the surviving Thrint build a giant telepathic Amplifier designed to order all sentients in the Galaxy to commit suicide on "Last Day". ("World of Ptavvs", MKW3 "The Asteroid Queen")

Durvash the Tnuctipun spy discovers a way to halt the impending Suicide Time, but his ship is thrust into Stasis by the impact of a Thrinti Godfist weapon that imbeds the tnuctip vessel into the molten crust of what will someday become the Jotun Mountains of Wunderland. (MKW5 "The Hall of the Mountain King")

A day or so before the Last Day/Suicide Time, Dnivtopun, Overseer of a food world in the 7-1Z-A (Alpha Centauri) System, his wives and his young son, suffer an accident that seals them in a stasis field. (MKW3 "The Asteroid Queen")
