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
