If sci-fi RPs interest me I might make use of one of these alien species. Descriptions are deliberately vague and haphazard with some exceptions. SUB-JOVIAN WORLDS -Mega Atmospherics (5) Large atmospheres, some solid ground abeilt with very dense gas. The Marata; Gas baggers that look like many flesh balloons, became space faring to meet their gods in the endless fog, somewhere up above. They found everything they knew to be wrong. The classic subjovian species. Kafurvast; Gliding, hiveminded civilization that kept going upwards to see what is up there. They found space. Aggript; Not really space faring, but have made a paradise obscured by the dense atmosphere of Agrippa. Totally caught us by surprise when we happened on them. Asksksu; In a massive world like theirs, empires rise and fall, and they have developed far. They know of space, but fear the stars. Instead they have militarized their world into a massive barracks. Okkus; Very advanced, as a species who had to develop from the ground to the stars on a gravity crushing world would be. The Okkus are strange in their imperial unity and hysterical design. They are like floaty maggots with many small legs. -Volatiles (“jungle subjovians”) (3) Life took off quite hard here. The Ephemeral; Short lived, mass produced species. Gluppy and slumpy, the Ephemeral built a tower complex to the stars, their path strewn in chaos. Quasians; Gliding, manta-ray esque beings who thrive in the chaos of the world. Managed to become space faring, developed themselves to be permanent space dwelling beings with lux drives jammed into their bodies. Krazzlehite; Beings of pure madness. Their fucked up design and fractal outlook has allowed them to spread like wildfire, across their planet. Count as postindustrial simply due to their sophisticated computing systems and massive, massive city complexes and floating islands they built. Reduced to a human client. -Saunas (3) Hot ocean planets with a thick, dense atmosphere of water vapor. Biypp; Hard to tell what they are, assemblies of beings made from material with machines of flesh and gas bags, technically a “industrial” civilization with computing systems and energy weapons. Vargynn; Serpentine beings whose legacy in the galaxy runs all too deep. Breathe mist instead of air, lived in a semi-state of land and sky. Glankiv; Abominations who now go across the stars senselessly devouring all. Their terrifying adaptability has allowed them to spread into any world with oxygen, genetic computing being all too innate to them meaning they just change to whatever planet they can access. -Semijovians (1) Subjovians like warm neptunes are what comes to mind. Ikkytsoss; A species built on gel, their light and fluffy world where everything is in free fall didn’t stop them from going to the stars, living in the warm under layers, ascending to the solar horizon and colonizing many gas giants. TRANSCENDANT The transcendent associated with this type The Virgo; Succesfully melded to reality, free to wander forever without a care in the universe. ICE WORLDS -Titanesques (5) Worlds like saturn's moon, but different in their own ways. Operiunn; Metamorphic, highly individualistic, and terrifyingly intelligent. Not the beings you want to fuck with. Zatraii; Splitting forever, splitting until there’s nothing at all left. That is how the zatraii work, much to their dismay. The Stati; Icy worlds, haha. They are like a mass of frozen beings, that animate and do countless action. Utter terror wherever they come to zatraii. Vantli; Literlaly live in oil most of their lives. Didn’t stop them from being ambitious enough to look around for other oil heavy worlds when they were in danger of sucking their wells dry. The Glum; Ancients who are writhing masses of tendrils of countless specialization. Massive in mind and body, they go about the stars feeding upon all life. On Titanesques. So they’re not our problem. -Bioicers (4) Live in extremely densely life filled and titan-like worlds. So dense life is, that life itself has aided some in space travel. Celestials; Colonial aggregate species, got so massive they dwell in the depths of space. Vaerkiff; They dream to kill us all. Like massive, monolithic snow creatures. Ottarnr; Frozen in peace, us all. The vast complexity of their world is hard for many to rival, even they have trouble. Snowflakes; Gel-like aliens who are very well known for their gestalts and ad hoc minds. Ritualistic behavior and total amorality. Despite all that, they managed to become space faring in time. -Subglacial Oceans (3) Alien beings who live in worlds with sub glacial oceans like Europa. Asantum; once a powerful force, these intelligent aquatic beings figured out how to make a spaceship underwater. Good luck beating that one. Havanda; Eusocial aquatic beings with many tasks, many organisms. Developed a swarm intelligence and managed to develop away from their world. Sparth; The Sparth as massive aquatic beings who dwell in the abyss. No one is sure how they got off their world or why. But they colonized again and again, without so much a thought to our existence. -Ocean Worlds (4) Ice worlds that melt become ocean planets. Laygyrflo; Extremely pressure tolerant aliens who did similar to the asantum, but with the advantage of having access to the sun. Dwelled between the ice caps and the depths, nothing really stopping them. Leviathans; The most impressive composite species of them all. Like massive living boats, with parasitic crews, the leviathans managed to make their way to the stars very slowly and only when they found other worlds with water oceans like their own; tolerate of so many seas, the only limit it would seem being they find our oceans claustrophobic. Jyppoza; Communal, intelligent and pretty much what dolphins might one day be, main difference being they have a prehensile tail fin while Dolphins do not. Managed to make advanced, postindustrial civilization and ascend to the stars thanks to all sorts of organic structures and fallen stars (meteorite islands) Storm Dwellers; Proof the line gets blurry with ocean worlds, the storm dwellers live on a exceptionally stormy world and have managed to make the most of it by harnessing the energy around them and launching off to the stars. They’re a mixture of balloon, seal and sea cucumber. -Ammonia Worlders (4) Worlds where water is replaced with ammonia. These worlds are very cold, but not as cold as the titans. Ammonia's properties causes a strange trend of electric channeling with ammonnia aliens. Virii; Another intelligent parasite. God damn. Sucking the energy out of everything, too. Esskkkriv; Thinks and acts not in voice, but electric currents. Their diplomacy is the best. Asshg; Enjoy living in subglacial liquid nitrogen/ammonia seas. They do. They also enjoy jumping Kuiper belt objects. Are literally the most transparent aliens to human eyes. The Flow; Intelligence in clouds, the flow are like individuals with souls distributed between many bodies. They see themselves as individuals that are separate, connected by the currents and all. -Silicate Worlders (2) Some ice worlds have rich silicones and the right place and time for silicone chemistry to actually happen. Pas; Silicone creatures living in icy worlds, dwelling on minerals and math for life. They literally feed on information and had to go off world to find better sources. They found the galactic community, the rest is history. Cyrtshka; They eat sand and shit glass. And than used their shit to learn astronomy. And eventually solve all work woes using fiber optics. ROCK WORLDS -Desert Worlds (8) Dry worlds that would be barren if they couldn't hold atmosphere. Has enough water that complex life develops, regardless. Aveterriat; Industrious space seals, power is in their blood. Usati; Communist Centuaroids! Run! Octimanos; Radially symmetrical, eight arms and all fun. Calzonit; Them… Vul’kut; Space raptors! Mullji; The original hive minds, as they always were. A beautiful sight, mole-turtles, a beautiful sight. Bobbit; Tall creatures who can on reflex become much taller. They are pretty fast as well. Shelli; Pretty much known solely for their thick shells and eccentric appearance. -Tropical Worlds (7) Hotter earths that remain being rather wet regardless. Qvkr; Amphibians in a world drowning in water. Lived in sea stacks. Yalilus; Love to sail the seas and the stars. Don’t seem to realize space isn’t an ocean. Vays; Radially symmetrical amphibians who are just plain insane. Terribly, terribly insane. Are very adaptable, too. Glindvvts; Gliding aliens used to the style of flight a tropical world needs. Inshyun; Pretty much hairy alien spiders whose webs sown and desire to build progressively led to some of the most massive structures in the galaxy. The Builders never stop. Sqibbi; Only intelligent as cocoons, these insectoids manage to make quite a cultured society in spite of that. Fumic; Weak, little and pathetic trilateral beings who came to rule the galaxy. -Garden Worlds (6) Earth-like planets. Called so because we have all these pretty flowers instead of giant fauna devouring flora. Humans; US! Vamusk; Humanoids the closest you get to mankind, but still alien as all hell in their own way. Natvyr; Hive minds who love time, electromagnetics and devouring everything in their path when they aren’t breeding like rabbits. Rovii; The true agents of chaos. Liliate; Composite beings with plants and swarm critters who commune to make life itself. They ARE THE GARDEN WORLD. The Vyle; Literal alien star fish. Innumerable and without any hope of ever reasoning. Sphericals; They live in the water, connect to grow smarter, look like spheres with numerous small tendrils. Managed space travel. -Jungle Worlds (Bioballs) (7) Jungle worlds are ultrahumid worlds that ended up with extremely, extremely complex biospheres unmatched by any other sort of life bearing world. Crrypcp; The Crrypcp are a composite species with parasites and more! Oh no! Urchinoids; Wanted to rip themselves out of the womb of their god. So they did. Are like land sea cucumbers. However, they still remain deeply insular despite having developed tech on par with us. Gaia; World ecosystem that started to seed many other worlds. Terrifying. The Growth; You don’t want to know about the growth. Pertarniar; Horrifying things from a tiny, very overgrown world. Like humanoids, but worse off. The Grippers; Very vertical creatures, with hands great for climbing and minds great for climbing to the stars. Silver Elves; More humanoid than vamusk, but are completely alien in every other way. They’re eusocial, their smarts relies of communes and they don’t have actual spoken language, just calls. Somehow they communicated advanced spaceship designs. -Slime Worlds (3) Worlds dominated in what can best be described as advanced forms of slime. These are very gooey worlds. Taysnoddi; Aggregates of slime, developed intelligence, ultimate tacticians. Technologically backwards by post industrial standards, but their cunning is unmatchable. Dread them. Astrogys; A civilized slime being, their fluid bodies and carapaces have made them surprisingly human-like in behavior. Except that they’re slime. Fucking slime. Anvayat; Brackish, tarry and full of energy. The Anvayat and their golden brick architecture make them well renowned in their mysticism and so on. -Sulfur Worlds (4) Worlds where instead of oxygen, there's sulfur. Have fun. Irrvrites; Dwell in the heat. Dwell… With them. They attain knowledge faster in their natural habitat, get brain dead in the cold. Must breathe sulfur instead of oxygen as well. Stickmen; Aggregates of many stick-like appendages, shifting from form to form. Also are sulfur breathing, heat tolerant creatures. Qrrarlbar; Burning in heat, these massive beings spread across the stars from a world that was slowly getting eaten by their dying sun. Whandi; Notable for ritual brutality and the belief beating the shit out of people is how you handle diplomacy. They are a very diplomatic species. Are trilaterals. -Methane Worlds (2) Worlds where methanogens remained dominant, oxygen never dominating. Ottrib; Oh god not them. They breathe ass. No one cares how strong they are or their natural swords, they breathe ass and that is all you will ever know them for. Shod; Behemoth beings who breathe ass. They are slow minded, but far better at thinking than we are. -Chlorine Worlds (1) Worlds where chlorine dominates the atmosphere, leading to acidic oceans and other fun traits like being instant death for people. Faberite; Fucking assholes. They pretty much kill just by being around and breathing, the faberites are these extremely surreal looking creatures who just don’t know when they are hated.
