Epochs past, the Karu system was the home of an advanced civilization. However,they were destroyed in a war of titanic proportions. The former home world is little more then a charred cinder, depleted of resources and furiously radioactive. However, born from the apocalypse is a new, strange planet, designated Karu II.
The planet is the accumulated remains of the wreckage of two unimaginably large battlefleets. Through millions of years of collisions and the impact of solar wind, the wreckage has collapsed onto itself forming a small, but very dense planet. During it's history sufficient amounts of transuranic metals collected at it's core and started a sustained nuclear reaction. The heat served to melt much of the metal that formed it, as well as creating a thick atmosphere from the myriad of plastics and other materials. This atmosphere is rich in many chemicals and is dreadfully toxic.
The planet is 500km in diameter but has a gravitational force of about 1.3G. It has a thick atmosphere with usable amounts of oxygen, but has a pressure of 3 atmospheres at 'sea' level. The remainder of the atmosphere is a devil's brew of hydrocarbons, radioactive gases, acids, and many other noxious chemicals.
Of course, this planet is considered a treasure trove of raw materials and even with its dangerous atmosphere, high radiation and powerful magnetic field, mining outposts exist. The mining is difficult, but there are few places in the universe with the same concentrations of pure metals.
The passage of millions of years has destroyed most of the technological artifacts of the system, leaving little of interest except to miners, and xeno-historians trying to seek the truth about that long past disastrous war.
Two to Tango
Obviously for there to be a war large enough to provide this much debris, the battlefleets would have to be the product of thousands of star systems. Though the expanse of time is immense perhaps some remains of the enemy species still persists. Perhaps they make a pilgrimage back to this system every millennia or so to mark their species victory.
Digging has uncovered a vast deposit of precious metals. The resulting rush on the small planet draws even more miners to the dangerous planet.
Not everything has succumbed to the march of time. An automated defense satellite, thrown into a tremendously long orbit now is returning. It's orbit will bring it close to Karu II, where it will use it's wonderfully advanced weapons to incinerate any alien presence. The PCs' will need to find some means to disable this death machine from ages past. Go to Comment
A giant Nanofiber balloon could surround the small planet to physically hold the atmosphere, assuming a material strong enough. Optionally it can be controlled to regulate the reflection of light and therefore climate. Go to Comment
Named for the astronomer who first located it, Estellas' world was an mystery for many years until it was finally visited by probes. The world possesses both a proper, oxygen rich atmosphere, and plentiful water, both facts being established early on via spectral analysis. But those did not tell the full story.
The planet is carpeted by alien machines of war of all description, but have deteriorated greatly over time, and little, if anything, is salvageable. Would-be scientists, explorers and treasure-hunters have to face an additional hazard. Virtually everything on the planet is highly radioactive, including many materials not thought to be capable of being radioactive.
Even materials normally used for radiation shielding become radioactive over time on this world, leading some to believe that something on the planet is disrupting matter on a level unknown presently to science. Some theorize a final weapon which ended the last war and civilization on the planet.
The planet is home to a primitive plant-like life form which seems radiation resistent, but little long term study has been possible. There are still those who seek the world's secrets, but the fierce radioactivity and quarantine battle satellites posted in orbit have so far dissuaded their discovery. Go to Comment
Eltridies III is an odd planet now a moon - trapped in a wild orbit around a magnetically powerful Gas Giant (Thorius V). The planet's twin iron cores are spun up when it's orbit takes it close to the Jovian, and during which radiation makes the surface uninhabitable. Once it passes outside of the main planet's magnetic field, its own field dominates and the surface is habitable. The world has a fairly thick methane atmosphere, is earth-sized, somewhat cold (average temperature 2 degrees C). Gravity is 1.2 earth norm, and has tidal effects when close to Thorius. While close to Thorius, radiation on the surface is severe.
The interplay between Eltridies and Thorius V is such that although the orbit should be degenerate, the magnetic interaction 'boosts' the orbit, allowing it to remain stable.
The planet's magnetic field is so strong that large metal objects are dangerous they have currents induced in them. It is this 'free energy' which makes the planet desirable. Huge plants collect the surplus electricity with little more then superconducting rails and use it to manufacture complex hydrocarbons, solidified hydrogen and antimatter which is shipped off planet. The Plants are underground and most surface equipment is retracted before the radiation level becomes high enough to irradiate it.
There are relatively few human inhabitants most functions are carried out by heavily shielded robots. The planet's magnetic field makes landing ships there a rather scary proposition for less-experienced pilots. Go to Comment
The world is a dimensional oddity. It and the system it lies in is displaced partly into another spatial dimension. As a result, the apparent gravitational force of the planet is less then one would expect given the observed physical dimensions. Similarly, its magnetic field appears weaker then normal but still manages to shield the planet from most radiation.
The planet appears quite earth-like and supports a similar biosphere as terran life, but with notable differences in its amino-acids. Natural flora and fauna need to be carefully analyzed and processed to be safely edible. Live has not progressed much beyond the Cambrian period on this world.
The planet is quite habitable and if it were not for its odd dimensionality, it would be considered a top-notch Garden world. Scientists have not determined what long term exposure to the 4th dimension displacement will cause, but in the short term they have found that anything brought into the planet's gravitation field will also be pulled into the 4th dimension as well. Again, an outside observer will see no change in the objects physical dimensions, but many natural forces will be attenuated as if the object were further away then they actually are. Gravity, magnetism, etc are slightly decreased. Light will experience a nearly imperceptible redshift. The differences are only perceptible when objects with different 4th dimension coordinates are considered.
If one gives this world a very significant 4th dimension difference, then the world will seem more an illusion then reality, one that becomes more real as the visitor is drawn closer on the 4th dimension.
An apparently normal world that suffers from massive earthquakes and severe gravitational variation.
Through some freak occurence - perhaps artificial in nature, the planets' core has inexplicably collapsed into three small black-holes which orbit each other in a wild dance which causes severe earthquakes and perceptible variances in gravitational pull. This world is in the process of collapsing into itself and only the low overall mass of the black holes prevents the world from simply imploding in one sudden collapse. The planet is in effect a Dyson sphere, but the inner region is too bathed in radiation to be habitable.
The planet is doomed to eventually collapse inward as the crust and mantle crumble over geological time.
This erratic gravitational field makes low orbit quite difficult - it is much easier at higher orbits since the tidal effects of 3 centers of gravity are mitigated by distance and behave more like a point source.
The planet, being so unstable and dangerous, is home only to a few scientific installations (mostly unmanned) and a few desperate miners. The world is quite rich in mineral resources, and there are the ruins of some lost race dating back hundreds of thousands of years. Go to Comment
"You got to be kidding me? We have to land there?"
"Yep, unless you want to sink a hundred meters under mud..."
This world was once a wealthy industrial world until it was pounded into dust during the Sith War. The world was pretty featureless before the bombardment - it had been geologically dead for several million years and most mountains had long since eroded away. The orbital bombardment had served to further flatten the world as well as melt the planets remaining ice caps. As a result, once the smoke cleared and the various vaporized materials settled, the planet was a great, dead, sludgeball.
The planet now is mined for it's high quantities of rare metals - the remains of its once prosperous society - that are suspended in the planet's 100-meter thick sea of muck.
Vast 200-meter long hovercraft are used to siphon off the much and separate the metals from the other material.
The muck itself is home to a small ecosystem of introduced species including a few large predators of unknown origin. The largest is similar to a giant squid and uses bioelectricity to find its prey, including the occasional worker on the hovercraft.
What few permanent structures exist are built on long, hundred-meter piles which reach down to the bottom of the muck sea, and the landing pads are infamous for their rather small size. Go to Comment
