An old 4X game for DOS called Ironseed, actually. =p

Reminds me of Felix of Golden owning the planet Sanction in the book ARMOR...


75. A planet that wobbles, possibly due to an extremely large (in relation) moon, causing odd jumps in the day/night cycle.

This one was a combination of Catalogue #34689 from the old PC sci-fi RPG Planet's Edge, and Elign (owned by the multibillionaire Modian) from the equally old PC spacefaring game Solar Winds.

76. An asteroid belt given an atmosphere by megaflora that also holds all the asteroids together allowing travel between them.


77. A huge conglomeration of space junk, ships, asteroids and the like, which has been pulled together by some unknown force.


My fiancee and I came up with three moons that I use in my campaign setting:

78. The Eye is large moon in the sky. Once the torn out eye of Gruumsh, it hardened in the sky into a moon. The moon features prominently a very large mountain range that rings a central lake visible from the planet's surface called the Iris. This lake is massive and reflects sunlight on the planet's surface, which is refracted to increase the temperature by 5-10 Fahrenheit across a vast region. The areas exposed by the sunlight have been known to cause tempers to rise. Fighting increases in areas under its gaze, and people ascribe its chaotic influence to both desire to fight under Gruumsh’s eye as well as ascribing it to supernatural forces.

EDIT: Lycanthropes are affected by this moon, by the way, resulting in mostly warlike and violent lycanthropes.


79 Yenog is a sickly yellow moon. Yenog, the corrupted version of Yeenoghu, is a moon that appeared ten of thousands of years ago, before most written records, and longer still before the Gnolls converted Bahamutism. Yeenoghu invaded a pre-existing high gravity barren rock moon and transformed into a toxic, sulphurous stronghold. She was defeated long ago, but moons retains its sickly hue, toxic atmosphere, and forbidden secrets.


80. The moon Siduri appeared in the last century, when it was summoned from an unknown location by a coordinated effort of worshippers of the God/dess of Darkness. The moon blocked most of the sun in a near total eclipse for 29 years as it hung in orbit, forcing civilizations to adapt quickly as surface temperatures fell dramatically and plant life unprotected by magic died out across the planet. The moon was kicked off its unnatural orbit, but scholars fear its irregular orbit may disrupt or collide other celestial bodies.


Do expatriated Yeenoghu worshipping Gnolls live on your Yenog?


81. An asteroid belt actually made of an ancient fleet of vessels, beaten against each other for centuries, millennia even.

Silver Crusade

82. At first glance, the planetary body appears to be just a broken, twisted landscape, until closer examination reveals the planetary mass to be an unbelievably large accumulated mass of bodies, mostly of immense outsiders and other non-aging beings all bound in permanent stasis and then kept preserved in the void as to hide the bound ones to any who would seek to free any of the ones imprisoned here. Seeking for the ancient one responsible for this will reveal the massive accumulation of bodies to be the work of a long-forgotten archmage of unparalleled power, who upon defeating any opponent that could possibly return to threaten him again would bind them in stasis and then cast a improved version of the Nailed to the Sky 3.5 epic spell to hide the bound foe and to deny allies the chance to rescue his vanquished foes.


83. A water world, around the small metal core are layers of coral. The intelligent life, are humanoid polyps that take root upon reaching middle aged. They build gravity guns that pull what they need from the void. There are floating cities that house other life forms, rescued from dying spaceships, used to build the islands. If an island gets big enough, it will become a water moon, then a water planet of it's own.


84: A gas giant that has become a mini solar system after having it's rings colonized
86: A gas giant that is expanding and "eating" it's moons.

87: The remains of a dead star that has cooled into a mass of solid, radioactive iron and nickel...and something old lives on it.
88: A Black hole that has enough mass to exist but not enough to draw in any surrounding matter. A giant, black mirror in space.
89: An asteroid field primarily composed of crystallized quartz and jagged volcanic glass. It's practically invisible to the naked eye.

They did, once upon a time. They existed at large temple cities on Yenog with portals to Gholeia (working name for my campaign's world). After the defeat of the power structure of Yeenoghu worship in the Gnoll world, many fled here. In the millennia since, the Gnolls and the others that fled to Yenog have since adapted to their environs, sharply contrasting their origins on Gholeia.

Thanks for asking that - I hadn't yet asked that question :)

90. Recent discovery of bleeds from the shadow plane into normal space have revealed a massive network of bleeds across the quadrant, allowing for x7 faster travel through the region (a la shadow walk). Business and military interests of regional powers are gearing up to exploit the new discovery, disregarding calls by scientists for further exploration and study before use.

RPG Superstar 2012 Top 16

91)Recent discoveries of shadow-infested abandoned space bases, both constructed and on moonlets or asteroids, tell a tale of how ignorant and greedy spacefarers using rifts into Shadow unleashed an umbral doom upon them all.
And all these stations have some sort of barely-sealed planar anomaly seemingly ready to rupture open nearby.

Hehe!

==Aelryinth


92. A gas giant incased in a miniature Dyson sphere, creating an exceedingly large living space around the planet with gravity equal to Earth.

93. A drifting piece of salvage, a interstellar ship whose drive mechanism was based around taking brief jumps into another plane of existance to move great distances in real space. But something came back.

RPG Superstar 2012 Top 16

94: A comet, streaming through space with a tail thousands of miles long. Except, you think you see something inside of it...
and more importantly, you think it sees you, too...

95) A fiery meteor shower, burning their way through the void. Wait, why are they burning where there is no atmosphere?

96) That nebula over there is gorgeous, little winking stars, multi-colored gasses, I could just sit and stare at it forever...

97) Hundreds of petrified bodies dumped into the void, race to be determined. They abandoned ship and petrification was used as the 'stasis' effect so they could be revived. Yet whatever made them entrust themselves to the void may still be with them...

98) Say, is that nebula over there moving? It sort of looks like it is extending tentacles or something out in our direction...

99) A literal crescent moon, looking like nothing so much as a gigantic something came along and took a huge bit out of it...

100) A world still a-borning, where raging elements and primordial beings contest with one another about what the world will be. Dominated by extreme elemental conditions and conflicts where the elements meet, with stupefyingly powerful entities leading elemental armies to war.

==Aelryinth


101) The heart of the sun. The center of the solar system is actually hollow for a layer. The "star's" hot bright visible layer sits on top of another layer of impossible alien gas that neither ignites nor turns to plasma from contact the sun's incredibly hot outer layer. Beyond that second layer is a third inner layer that is habitable by life. In ages past, gods from many galaxies and planes created such suns (hollowing existing stars with their shared magics) to make colonies where the incredible energies of the outer layer could act as a forge for new planets or even new laws of nature, slowly wrought over millennia.

That ancient civilization of gods is gone, unremembered, and nearly unimaginable now, but the incredible power trapped there calls for new masters.


102. A dead planet, about the size of earth(or whatever the homeworld is called), and dotted with ruins. The archeologists have set up bases to study the ruins. Strange people have shown up, asking about terraforming the whole planet. It turns out, the previous residents invented time travel, and their regaining their homeland will destroy the ruins.

RPG Superstar 2012 Top 16

103) as a twist to 102, you've found the previous inhabitants, thousands of them, petrified to wait out the catastrophe that claimed their home in caverns. but, if they are released, you lose out on all that sweet, sweet plunder...and their homeland is still a wasteland.

What do you do when 100,000 members of a strange race need to be unpetrified? And what if doing so unleashes the same fate on you that doomed their world in the first place?...

I know you have 101, yet I want in on this -

104) A massive 100 AU Dyson Sphere that uses it's sun not only as an energy source, but powers its ability to propel itself through the universe.

105) Five planets sharing an orbit. Should they ever collide and combine together, they will form Megaplanet (cue theme music).


106) The Noisy Nebula is a hazard for travelers. There is enough gravity to pull gas clouds together but not enough to form new planets or stars. The unusually high amount of gasses allows sound to travel - thus it's name, which was named for the mysterious sound waves that echo the nebula. The hazard comes from concentrated sound waves shattering ships apart in seconds.


107) Astronaut's Folly is a landmark/tourist trap located on the second moon of the uninhabited ruined world Ak43172c. A businessman named Mr. Quick built a small, pressurized space station/luxury resort on the surface next to the ancient monument, which is a perfectly preserved archaeological site, complete with a lunar lander craft, a motorized vehicle, and a shimmering blue, white, and red pennant held in the hands of a dead astronaut. The name of the monument is derived from the fact the astronaut died of a rip on it's suit, caused by an another flag pole that caught the suit near the calf on of the creature's three legs, still hooked to the suit. Inside the lander, there are boxes of the same pennants, with alien text, which translates to, "When we touch the stars, we become the Gods themselves."

Edit: if you push a red button in the lander while it is pressurized, it plays music and gives a speech about the sacrifice and courage of their race.


108) Philosophers stone veins have been rumored to be discovered on a planet in the disputed territory of two large empires

108) Love's Folly is a world trapped in an unnatural twilight, with communities of Halflings huddled around light-generating magical stones that sustain their communities and crops against the eternal night that exists beyond the range of the stone's magics. They war from time to time over stones, or steal them from each other to expand one communities borders (at the expense of another), and shadow goblins dwell on the fringes, always ready to snatch any Halfling bold enough to leave the safety of their lit areas. Thousands of years ago, the world was like any other, lit by many thousands of stars in a perpetual dim light, but a Halfling commoner promised a princess that he would prove his worthiness by bringing her a 'star from the sky' to wear in her hair. And he did, stealing a star, which, on this world, were glowing gems fastened to the inside of the crystal shell that surrounds their world and isolates it from the rest of the universe. That act set off a devastating trend, and soon the rest of the 'stars' had been plundered either by residents of the world (as every high station Halfling simply had to keep up and wear a 'star' on their person), traded away to extra-planar outsiders in exchange for various services, or stolen and hidden away by the shadow goblins, who reveled in the dimming of the light, and the greater range of freedom they were gaining at the halflings expense.


109) Here's one from my Star Trek Fan Fiction Days: The Tars Tavik is a small nebula, only 24 light years wide. Inside this cloud of stardust, half a billion refugees are spread out across six star systems, living illegally in planetary junkyards, weapons testing grounds, and colonies that were abandoned by the major galactic powers. It's name, Tars Tavik, literally means Long Night or Haunted Night because old spacer legends claim the Nebula is haunted,
110) The Maw is a huge, swirling black hole. Prior to it's formation, the Maw was once two huge binary stars that both collapsed into singularities within twenty years of one another. After just a thousand years, the two massive black holes became so close that they are now indistinguishable from one another. One giant black hole that is sucking in nearby celestial bodies.

I like this - reminds me of the halflings in my setting during the Long Night of my setting (see number #80 of this list), who are mostly semi - nomadic pony riding barbarians that take the best traditions of ancient Mongolia and Tolkien.

110) A giant shield built to keep roving pirates and vandals out of a wealthy solar system remains standing after a thousand years.

A Halfling rogue was my first (randomly rolled) Spelljammer character. He had a gem of brightness as random treasure, and that was the backstory I made up for him, that he'd stolen a 'star from the sky' for his sweetheart, and it all ended tragically. (At least, that was the story he told others. The truth may have been wildly different...)

A variation on 110...

112) A dozen small worlds orbit at wild speeds around a black hole, lit only by the light of other nearby stars. They have been in this precarious orbit for millennia, skating the surface of oblivion like droplets of water skittering over the iron of a hot pan, but somehow never quite being drawn in or collapsed. You can, if you target very precisely, land on one of this worlds, but, due to the gravity nearby, you're unlikely to ever be able to leave, save via teleportation magic, which makes these worldlets popular 'vacation getaways' for high level (usually undead...) spellcasters.

Reminds me of my first pc when 3.0 came out, a halfling wizard who hung out in the human fighters backpack because he was so light.

113) A lush swampy wetland populated by short, green humanoids wIth large ears and psychic powers is a magnet for those seeking the secret to immortality, due to the legendarily long life spans of the inhabitants lasting into millennia.


114. A ring of tangled vegetation encircles the central star, like a Christmas wreath 100 million miles in radius. The ring is dotted here and there with colonies of one sentient race or another, but it is mostly unexplored simply because it is so big.

Oh, Dude:

Captain Esker rolls out the map across the table and looks around to ensure that the barmaid was gone. Quietly, the cyborg slides a metal finger across the tattered plasticine. "Aye, Lads. The Vaultworld of Ethos, closed for a thousand years after the fall of the Ethosian empire! Impenetrable...until now laddies, cause I've got a keycode. Maybe one of the only keys in the universe. Now...who's going with me?"

115. Two dead massive moon-sized giants impaled upon one another's weapon. Each is encrusted with life and debris from the solar system. On each of the giants two oppossing and unique ecosystems exist. The inhabitants of the giants are constantly at war with one another marching across the land bridge formed by the giant's weapons. The severed arm of one of the giants orbit the two bodies as a natural satellite.

The arm is populated by ancient survivors of the war that killed the giants and view the fighting as pointless and tragic. They know that the atmosphere for which everyone breathes is compossed of the combined gases generated by the decaying bodies of the giants and that the weapons themselves are constantly drawing resources from one giant to itself creating a natural resource cycle that all life of these two worlds rely upon, making the lifeforms of both giants in essence symbiotic to the other.


116. A gigantic spiderweb stretches between several asteroids. A passing ship has gotten caught, and it is now completely wrapped in the webbing.

Liberty's Edge

117. A former high-tech metropolis whose civilizations were struck down in ice and fire and terror. Now, only ruins and savagery remain.

118. An asteroid imprisoning so many ancient and terrible things that half a dozen Draikania are in minimum security. And the warden is dying.

Oh my... Is the warden a demi-god???

Mortal, just extremely long lived. Maybe a mythic tier or two of Guardian.


119. The last remnant of an alien species entrenched on the moon is the last line of defense against the Formian invasion. If only the inhabitants of the orbitted world knew about any of that.

120) Planet in a figure 8 orbit around 2 stars- "positive energy" star and "negative energy" star- good is empowered when it orbits "positive" star and evil is empowered when it orbits "negative" star- balances when it gets close to middle of the figure 8 orbit

currently in "positive" orbit but is heading towards center of orbit (center of the 8) and bad guys want to break its orbit so that it only orbits "negative" star and evil is empowered- can our heroes stop them in time or even break orbit of planet so it orbits "positive" star only?


121) Planets in the region of the Gulgrave Quasar cannot sustain Undead due to the high amounts of positive energy being generated from the black hole within the quasar.


One end of a wormhole=OEOAW
122) OEOAW Leads to opposite side of galaxy.
123) OEOAW Leads to white hole that prevents forming of undead within 10 light years.
124) OEOAW Leads to Parallel world. That homebrewed world you have been dying to run!

Or, 'yes, to all?'

126. A planet designed as a battleground by the gods, wherein they pull, send, or conscript beings from across the galaxy to do battle in their name.

Sounds like a Marvel Comics plot line.

No reason to. Superhero comics have been around since 1938, with dozens and and many eras hundreds of separate titles each month. There really isn't much we're likely to think of that hasn't already appeared in the comics at least a few times.
