125. Space whale cities.

Cities built on the back of space whales, or cities built within the bodies of (alive, undead, divine?) space whales, or flying steel and stone flying cities in space shaped like whales, or cities entirely populated by tens of thousands of space whales?

Or, 'yes, to all?'

:)

Space is big. I vote for E) All of the Above.

Yes though I was thinking mostly the 1st one though I like the rest. A whole bunch of cites built onto whales which themselves live in a giant whale shaped city.

127. A gas giant full of incredibly hostile creatures. Civilization exists on the numerous low-hanging moons of the planet, which have developed ships to sail the "skies".

128. An uncolonized paradise, guarded by an armada of Qlippoth.


129) A star system has an unnatural 15 planets in the habitable zone. They are kept in artificial orbits guided by coordinated Illithid God Brains. To the outside observer, they see large barren rock worlds in a dying system accompanied by anomalous radio waves. Illithid magic, psionic, science and technology disguise the terraformed planets, with cold cores but hollowed out by the teeming trillions of Illithid plotting the rebirth of the empire they lost at the end of time. The secret shipyard where they store the remaining advanced Nautilus capital-class starships is located near the white dwarf at the system's center.

If its purely PFRPG, replace Illithids with Neothelids for equally terrifying results.

130) An Elven arboreal planet is defenseless against a Hoth fleet using artificial gravity wells and slingshotting large asteroids to adjust the orbit of the planet into a cooler habitable zone. For the Hoths, -60 C sounds perfect, but that will kill most life on the planet. The Hoths are a civilization of intelligent spellcasting Remorhazes.


It would be interesting to try to connect all of these together as nearby systems and figure out which of these are in the same systems. Any else interested in that?

131. A Gas giant which all but one of its moons have all been destroyed and turned into rings in which ice and earth elementals make there home, a Dwarven mining station is set up the last remain moon, though they mainly mine the rings themselves.

That combined universe would be interesting. It would be funny to put that Illithid post I mentioned next to my campaign world, which is being invaded by Githyanki because its the Gith homeworld and is the supposed burial place of Gith.

132) An world filled entirely with ghost/spirit civilizations

133) A cabal of gnome wizards are using a variety of simple perpetual motion machines using magic to reverse the flow of black holes. By simple, I mean permanent [I] animated objects [\I] in the form of gears, golems/undead on treadmills, and similar spells that bask the laws of thermodynamics that any relatively low to mid level caster could muster.You know, nothing game breaking ♡

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.

twist on 119

134) the worlds last line of defense is a nother formic creature race (ant like) that is a part of a acacia style world tree that has its ant creatures addicted to its sap.

135) A planet that has hundred mile long tentacles


136. The Oort cloud hosts numerous objects of various sizes, among them lies an object which design is obvious not from this solar system and doesn't appear to be built by/for humanoids. The object is quite warm for its size (30 miles) and even has a breathable atmosphere that extends 20ft out.


137. The original homeworld for one of the core races (human, elf, dwarf, halfling, gnome, orc).

This is based on my headcanon/homebrew theory that each of the core races is originally from one homeworld where they evolved and developed naturally (Earth in the case of humans), and genetic material or sample populations were taken/stolen/persuaded to travel via portals and/or ships to other planets (game worlds) by deities/ancient beings/seeder cultures.

Such transfers could have taken place at numerous points during Earth's existence, hence dinosaurs, Neanderthals, and the multitude of various Earth cultural/racial analogs spread across many campaign worlds. Not exactly true parallel development between game worlds, but parallel nontheless and for a very good reason.

Some explanation would have to be supplied for half-elves, half-orcs, and other (mainly human) half-whatevers. Was the non-human race also originally from Earth, but transformed radically enough en route or at the destination, that the result was a completely new race (albeit able to produce hybrids with humans)? Or are orcs simply Neanderthals allowed to develop without interference from Cro-Magnon humans? Could elves be an earlier human strain which went in a different direction (possibly with outside assistance), like that branch of the human evolutionary tree labelled something-"gracilis"? (Yeah, I'm too lazy to look it up right now. :p)

So who is going to dig out their old Spelljammer books and list out those worlds? :) And then we can go down the list of Star Trek episodes...

Lol. I haven't heard of Ego before. Is that what Neth the living demiplane was based on?


Well, Bellona, the golarian home system has a seed ship style planet.

Ego is from Marvel comics. Mogo is from DC comics. A living location/planet/structure is not really a new idea, so I wouldn't claim Neth was based on anything in particular.


139) An undead, formerly living planet travels from system to system seeking a cure for its undead state, destroying planetary civilizations in a fit of rage when they can't help.

Liberty's Edge

140. A warship which plans to invade the planet, with their main weapon being Ooze bombs.

Blake's 7 had an episode about a living planet, and it's parasites.

Wander over Yonder met a living planet that got clingy recently.

141) A prismatic hole


It's been a while since I've posted here. Let's see what I have.

142) Tortuga, a roaming base of operations for space pirates across the galaxy. Harnesses asteroids as both camouflage and weapons.

143) An old, sleek artifact the size of an asteroid. From an advanced and long gone alien race, it could be a gateway to a network of warp holes leading to other galaxies. Or perhaps it is a superweapon capable of destroying all life on a single planet. Who knows...

144) A planet covered entirely in ice that wars with the denizens of the ocean beneath the icy sheets.

Liberty's Edge

155. A planet whose entire population was wiped out by numerous great monsters, who in turn starved to death. Now there is only science.

You mean silence? I found myself looking around for a Heterodyne...

==Aelryinth


146. A Gas Giant that so close to its star it's running through its atmosphere creating a counties blade of solar flare that follows it's rotation.

Liberty's Edge

147. Barsoom.

And yeah. I meant silence. Though science could work too,


148) An unknown source of magnetism in the Mardigar system wreaks havoc with un shielded craft, and has altered the path of nickel and iron asteroids to fall on an uninhabited moon.


Wow we are certainly past 101

149. Slow moving space ships full of undead.

Liberty's Edge

150. A centipede the size of Africa seeking to lay it's eggs.


151) A moon made of Wensleydale cheese

Quite true, but something went wrong there ...


Bellona wrote:

Possibly if I remember correctly we are never fully told anything about its purpose or anything else. But that's why it's such a good place for a campaign it's not limited in many ways.


152. A large elder earth elemental decides to rest in deep space and is colonized by a lashunta seed ship. The earth elemental is awakening and doesn't find itself to excited with its new inhabitants.


153. An ancient planet has passed through the realms of dreams and fantasies. A lady from there calls herself "The Placement Manager", and is secretly placing orphans with childless couples. The children seem unearthly clever. Those with a ring of X-Ray vision claim these children have 2 hearts. The planet might have to go home at a moments notice. It depends on someone named "The Doctor".


154) A planet covered in oceans and rivers of coffee. Locals have adapted, but foreigners must make fortitude saves each time they consume "brown water" or suffer increasing doses of caffeine.

Liberty's Edge

155. A mining colony carved out of a dead god's head.

RPG Superstar 2012 Top 16

156: A world with no adults. The place is infested with a virulent disease that rapidly kills anyone that exceeds puberty, but reduces the aging of anyone younger by a factor of 100. Thus anyone who is no longer a child, dies rapidly.

157) A world brought to ruin and occupied only by monsters and the remains of an advanced civilization. There are only two sentients left on the planet, both members of psionically gifted races, whose only desire is to kill the other and 'win' the mutual war that killed their peoples.

158) A mythic inevitable sealed in a stasis box, often known to conceal precious treasures from ancient times. When freed, immediately sets out to start properly 'ordering' the Prime plane, co-opting the PC's ship to get around. The only way to destroy it is catch it in a logic trap and make it realize that it is not perfectly ordered, forcing it to 'correct' itself via self-destruction.

159)This system does not have a proper sun. Instead, two portals of positive and negative energy stand opposed to one another, and when their streaming energies meet, the continuous matter/antimatter explosions form the basis of a 'sun'. As the portals rotate, the shadow of the negative energy throws 'night' across the system.

160) a Ringed World, complete with polar space elevator. The habitat ring has been shattered into wreckage and debris, but who knows what treasures might lurk in such a massive artificial ring, or what might remain on the planet below? (Think Kuat driveyards)

161) A world occupied by hovering, inverted mountain tops used as cloud cities, anchored to the grounds far below where rare metals and valuable ores are extracted from the toxic, poisoned ground and atmosphere by mining crews. The winged natives are the only ones that can tolerate the poisonous air, but only the terrestrial race can tolerate the working of the ores and metals, forcing a symbiosis on the different races to survive. (Think fantasy Bespin)

161) A flatworld, with lifeless mountains on the cold, dark underside, and a fantasy land of great size ringed by thousand-mile high mountains keeping in the atmosphere. Twelve great rivers fed by portals in the deep central ocean flow from the mountains and keep the ecosystem moving. Lit by #159.

162. A regular non magical apple that is just floating in space. Not rotten, not frozen, just an apple floating through space.

Sentient fruit bats and worms have both landed colony ships and are trying to claim the apple.

RPG Superstar 2012 Top 16

What were those worm guys called again? Silithar? The bats are desomodans, I think...

163) An old, cold system where the sun is a cool red...and nothing is orbiting it. Not comets, not meteors, not rubble, not asteroids, not worlds or moons. As if they were all consumed, or wiped away...

==Aelryinth


164. "It is said, the comet always precedes them, these world enders." Taken from Chronicles of Riddick and similar to other comet references above, but instead of something "trapped", the comet is literally the herald of <insert BBEG & minions here> from <plane/planet/whatever> and their invasion force (which is arriving, not might arrive).

Edit: I used this in 3.5 as the final act of a long-running campaign. The comet released the "Color out of Space," which at the time I had to treat as more of a near-divine entity, as I didn't have game stats for it. Made for an interesting finale.

Thanks. Can you find some mouse people to invade the cheese moon?

165. A 'negative-gravity' singularity (more implausible than a thousand green space babes!). You may ask why it remains near the sun when it should be repelled by any mass: well, the fact is, it is fleeing the sun. But the sun is attracted to an equal degree and keeps chasing it, dragging its halo of planets alongside it. The NGS is very handy when you need to get to other planets in a hurry, since its un-gravity well is a "trampoline" and much safer than messing about with regular gravitational slingshots.

166. A moon-sized mass seemingly consisting of the universe's largest carnivorous blob. Having engulfed all other animal proteins on its world, it has settled into dormancy and now looks like a plain of dark red ice. That is, until unwary space travelers tread upon it, and (in their innocence) carry particles of it back to their own world.

Homer: Mmmmm... world...

There's ratfolk in Pathfinder. Color 'em grey and give them big pink ears, and I think you'll be fine.

And that moon better be of green cheese.

167) A world made of apple pie, with seas of ink, and all you can eat are bread and cheese, the only thing you can drink is...PABST BLUE RIBBON! (credit to my grandfather, may he RIP.)


If all the seas are ink,
here's what we'll do.
We'll climb up a mountain,
and drink in the view! :)

It rolls off the tongue better if you go:

If all the seas are ink,
Then here is what we'll do.

We'll climb up top a mountain
And then drink in the view!

Nice reply, however!

168) An abandoned stellar observatory upon an asteroid, floating out in the middle of nowhere. The great steel plate is cold and still, but the telescope inside is far more advanced then any the characters have ever seen. There's at least 167 fantastic sights visible through it, if they can get the dome working to move it around.

Hehe clever.

169) A planet where the atmosphere is deadly, save for valleys below sea level where life ekes out an existence.


170) A planetoid made of radioactive metal and stone. Androids and robots that feed off the radiation live here. Post apocalypse game worlds will be invaded because their radiation is slowly fading.


171)Cosmic ophthalmos: a comet or artifact used by a archdiviner to explore the cosmos remotely

Liberty's Edge

172. A planet where gravity is so strong tripping over a rock can kill you.


1 person marked this as a favorite.

173. A planet with no atomosphere which has a very thick iron and nickel shell. A few kilometre thick area of lava, very thick layer of dirt and stone, huge glowing vegetation which grows almost all the way to where the core is which is just breathable air.

So a reverse planet sort of.


174) A planet with ruined cities on the surface but teeming with life underground, due to surface life being wiped out by a secret group using locate city bombs on surface settlements.


1 person marked this as a favorite.

175. A Brown Dwarf surrounded by a system of large moons/planets. The Brown Dwarf does not emit any significant amount of visible light, but frequent magnetic storms erupt in its upper atmosphere, sending electrical shockwaves throughout the system.

When these shockwaves strike a planet in this system, their ionospheres light up with an effect much like our Northern Lights, only these lights appear all over the planet and simulate "daylight" there, only on these worlds daylight consists of wild colours in the sky and the length of these days are irregular and unpredictable.


176. A sun that somehow started yellow, went red, then finally collapsed forming a huge diamond. Space Drow live on the planets supervising the Ogres who mine the diamond. The gravity on the diamond is so bad, only Ogres can tolerate it without magic. Some lichens and bugs can too.
