Yes, there's actually a really cool mechanism to roll 9 dice, come up with a funny sounding name and have your own species, with at least the beginnings of a history and culture and all the stats you'll need to fight it.
Alright, here we are once again with a Tale of Three Galaxies.
For reference, our own Milky Way is an oblong disc, 100,000 Light-years on the long axis. At the core, the disc shape is 3,000 LY "thick" or "tall" while for much of it's circumference it is 'only' 1,000 LY.
Of the Three Galaxies, the Corkscrew is easily the largest and most populous. It is 90,000 LY by 2,000, I usually think of it as being 90% the size of our galaxy which is technically inaccurate but close enough. Thundercloud is the middle size galaxy, 30,000 LY on it's long axis and 2,000 LY thick. The Anvil is a dwarf galaxy, 20,000 and > 1,000 LY.
CCW
The largest 'empire' is the Consortium of Civilized Worlds (CCW) and it's, well, it's the Federation packaged differently enough to avoid lawsuits, and with a few of the things that drive fans nuts tweaked or fixed. For instance, in the CCW's idea of a Prime Directive there is absolutely nothing wrong with landing a shuttle and telling the primitives that starships and interstellar civilizations are a thing, and they'll cheerfully set up embassies and/or trading posts. Now, they won't meddle in the internal affairs of a primitive people, and they definitely won't share any technology or science, but they WILL render humanitarian aid in a disaster. They're not apathetic
monsters, they just don't want to take a chance of exploiting other people or getting involved in complex issues, which they'll cheerfully admit to the faces of people asking why the CCW doesn't do more for them. But they also treat even primitive people like adults and don't sneak around behind their backs taking photos like they were an interesting species of bird.
The CCW grew out of an alliance between the humans of Terra Prime (there's something like 20 planets called Earth, and twice as many called Terra, Terra Nova or some variant in the 3G.) and the Noro of Noro-Gar, a peaceful telepathic people, the vast majority of whom believe that they were divinely appointed mediators and peacekeepers to the entire universe. Add in the stubbornly honorable pseudo-Roman Wolfen, the Seljuk escapees from Jurassic Park and the radioactive Catyr and you'll have all the most numerous and visible of the Consortium's 200 member species from 5,000 worlds. The CCW covers a third of Corkscrew, half of Anvil and 20% of Thundercloud. 7 Trillion live in the Consortium of Civilized Worlds.
All the Consortium Worlds sign the Civilization Compact, they're big fans of minimalist government (funny as that will sound in a minute) so it's a bare-bones basic thing. Slavery is absolutely forbidden, all the undersigned recognize the right of all sapients to own property, and to democratically elect representatives to the CCW Congress, military conquest of sapient species is absolutely forbidden, and to ensure it all colonization missions must be approved by the CCW government. And that, as far as I've read, is the extent of it.
CCW government seems roughly American-Britain modeled. Executive power is held by a dozen Ministers, including a Prime Minister, all of whom are elected in a general plebiscite every 6 years. The power of legislation rests with the Congress. Every world gets at least one representative, with more being added as certain requirements are met for a greater population, or economic and military contributions. No number cap, so we're dealing with a legal
minimum of 5,000 representatives, and probably far more. To save time, the Congress elects 200 of their members as "speakers" and only speakers are allowed to debate or ask questions, the rest listen and vote. Even so, the CCW Congress is infamous for it's ability to get nothing done. Then you have the Galactic Courts, the one system guaranteed to move slower than the Congress.
I won't lie, there's a serious dark side to the Consortium. With all this weak government, there are a couple dozen brutal dictatorships that have realized they can get all the benefits of CCW membership so long as they mind the letter of the Compact, which really does nothing to prevent a great many possible abuses. Chattel slavery may be outlawed, but indentured servitude certainly isn't... Even so, these represent less than 0.5 percent of the CCW. On the other side of horrifying, the CCW has 20 'Utopia Planets' that are obscenely wealthy, beautiful, populous (10-20 Billion, with none of the expected issues like crowding or pollution) where the average life expectancy is double that of the rest of the Consortium and where the poor are, by the standards of the rest of the galaxy, upper-class. Naturally, immigration is tightly controlled. Being wealthy, with useful skills and no criminal record may not get you in, but anything less guarantees you have no shot.
The CCW maintains a very strong defensive force, even the Noro recognize the necessity of self-defense in a violent universe. Consortium Armed Forces Fleet Command (CAFFCO) trains their officers to be highly flexible, technically and scientifically literate, and able to use their initiative. The hope of every young officer is that they will prove worthy and be moved from the regular CAF defense force to the elite Discovery Corps to explore strange new worlds. Yes, they have a military that does some exploration, and holds the explorers up as an example, but at the end of the day it remains a military and there are far more men standing a post than studying some nebula. Be still my heart.
Other than that, the Consortium has a combined FBI/CIA agency (dangerous to mix police and intelligence functions like that) called GalSec. Aside from investigating crimes that involve spacers or multiple worlds, they provide intelligence on and covert operations against the Consortium's enemies. Because they're not idiots and not the totally squeaky-clean Federation. The final major agency is TVIA, which investigates breach of the Compact, the Prime Directive, or abuse and exploitation of primitives. TVIA has recently been rocked with corruption scandal, losing much of their credibility and is now obliged to spend a great deal of time and effort policing itself. The three-way service rivalry between TVIA, GalSec and the CAF is legendary, and shootouts between the forces, though rare, are not unheard of.
TE
Next greatest by population and space is the Transgalactic Empire (TE) with 6 trillion residents covering one third of each of the Three Galaxies. The Empire is an outgrowth and refinement of the earlier Kreeghor Dominion.
See, the Kreeghor are a race of lizard-men, 6-8 feet tall, much stronger and tougher than humans, with better reflexes and mild regen. They were either created or uplifted (I don't know if even they know) by the Splugorth to serve as shock troopers. But some millennia ago, they overthrew the Splugorth and started their own interstellar empire. Since they've always had a warrior culture and something to prove, they set out to conquer the universe. It's a bit sad, but the present Empire is a huge improvement on the old Dominion. They used to kill and enslave everyone they defeated, and acted like dumb thugs in all things. Now they let some worthy species become subjects, still second class citizens to a Kreeghor born, and while universal domination is still the ultimate goal, they've come to understand that diplomacy can undermine their enemies far more effectively than brute force.
The Kreeghor are now a minority in their own polyglot empire, composing a quarter of the population. Like the CCW, they have a sizable Human and Wolfen population. They also have Machine People, reproducing androids of living metal (T-1000) um... more on them later. And Silhouettes, shadow people skilled in magic.
There are about a million Royal Kreeghor, a subspecies that is larger, stronger, has 10x the regeneration, is immune to mind control, and has considerable magic and psychic powers, unlike the more mundane examples of the species. This group is not the creation of the Splugorth, but appeared around the time of their rebellion quite suddenly and mysteriously (like the Ethereal Caste) leading many to speculate that the Kreeghor really just swapped their public masters for private ones. Royal Kreeghor are very nearly above the law. The Kreeghor are ruled naturally by an Emperor, chosen every thousand years from among the Royals. The Emperor has upgraded from 'considerable' psychic and magic powers to 'vast' powers. When a new Emperor is chosen, the old one accompanies him into the palace catacombs, and only the new one emerges with all the powers of the old. Even the fanatical palace guardsmen have no idea what they protect down their.
Probably a good thing, because the conspiracy theorists are right. Beneath the palace lies the Dweller Beneath the Palace, the (probably) mad supernatural intelligence that really rules the Empire. Like many such intelligences, the Dweller survives off suffering and blood sacrifice, and the suffering of a police state and the sacrifice of everyone killed by or in the name of the Empire have glutted it and made it insanely powerful. Ultimately, the Dweller wishes to physically and psychically consume the entire Megaverse. To get there, it wishes to devour the Cosmic Forge and steal it's power. But first it has to find the Forge, and conquering the Three Galaxies strikes the Dweller as the best way to look for it. Only the Emperor, and a handful of Kreeghor Witches recruited by the Dweller, so much as suspect the truth.
Outside of that, the Kreeghor remain a culture of warriors, and most of their population, even scientists and bureaucrats usually serve the war machine in some way. The Kreeghor contempt for matters outside of fighting has lead them to leave much of the administrating in the hands of their subjects, particularly humans, though the Emperor and his Privy Council are all Royal Kreeghor. In fact, they don't even care that how normal corruption has become. As long as the trains run on time, who cares how many paper-pushers are skimming off the top?
A consistent frustration of the Kreeghor has been their ongoing failure to duplicate Splugorth bio-wizardry. But their experiments with genetics have turned up a process for giving random superpowers that is 50% effective! The other half, of course, being subjects who die in terrible agony. Volunteers for this process are inducted into the Invincible Guard, the Emperor's fanatic bodyguards and personal agents, and the Empire's answer to those pesky Cosmo-Knights that keep causing trouble.
The Kreeghor have (for the moment) an uneasy "peace" with the CCW where both sides recognize that war would be disfavorable at this time, but also that it has happened before and inevitably will again. Both sides engage in proxy wars and undermine the other economically and diplomatically wherever possible. Most recently, (like, 70 years ago) some two dozen TE planets in Thundercloud have rebelled against the Empire and formed a "Free World Council" and thanks to the rebel's own cleverness, mercenary fleets, intervention by Cosmo-Knights and sabotage by GalSec, the rebellion has not yet been crushed like tiny insects. In fact, it's become an ever-growing pain in the backside.
UWW
The United Worlds of Warlock (UWW) are the largest magical star empire in the Three Galaxies. Never-mind it's the only major magical empire besides the Splugorth. The UWW claims 20% of the Anvil, a handful of planets in Corkscrew, and some 500 billion souls. The Union came about when the Elven Star Kingdom formed an alliance with the Warlocks of Tempest (nasty planet that's pretty much an Elemental's playground) to resist the Splugorth, which largely failed until their magic SOS was received and answered by the Dwarven Guildmasters. So Space Elves, Space Dwarves, and human spellcasters all formed a sort of government. The UWW is the only government that's a lighter touch then the CCW, they don't even forbid members from warring with each other, but if they pick a fight with an outsider, they're officially out and on their own.
The UWW has a Parliment with two representatives of each planet and the entire governing councils of the founding members. They have a president, though he's called a consul (King Silverlight of the Elves, now serving his 102nd consecutive term) and an election once a decade. The Warlocks are friendly trading partners of the CCW, on somewhat frostier terms with the Kreeghor, and actively support the Free World Council.
There's also a Dwarven Forge World called the Smithy. That is all.
Splugorth
The Splugorth in the Three Galaxies are a bit thin on the ground, mostly because of those damn Cosmo-Knights, and the many failed invasions of Phase World, though every other spacefaring civilization deserves some credit. 80 billion Minions and a mere hundred worlds. It's gotten so bad, the Splugorth have fractured into 4 distinct kingdoms, each ruled by one actual Splugorth, and spend more time fighting each other than their enemies, though raids by Splugorth slavers remains a constant danger in the Three Galaxies.
Paradise Federation
A series of 26 vacation worlds scattered throughout the galaxies, administered by the Paradise Foundation independent of any government. The Paradise Federation offers every possible entertainment and vice, and their extensive drug and slave trafficking has driven the CCW to try and shut them down or at least stop their citizens from going so much, but every attempt has failed. Supposedly, the Naruni support the Federation.
Mechanoids
The Mechanoids exist in the Three Galaxies, luckily for all humanoid life the Mechanoids that exist now are a pale remnant of their once terrible glory, and the Mechanoids in the Three galaxies are just a small fragment of their much depleted race. Of course, all it takes is one Runner to be left alone for a couple of years and the Mechanoids are a going concern again. But their numbers are limited enough that instead of rolling over the galaxies in a great wave, a handful of ships a year vanish, sometimes a colony world goes dark, then someone catches on and sends a massive fleet in panic mode to wipe out the Mechanoids. They succeed, at great loss of life, but a couple of Mechanoids escape and after some months or years we start over. Nobody wants to deal with the Mechanoids in force.
Dominators
AKA, the reason there aren't any elder races.
Take the most badass version of Darkseid you can think of (no, Smallville doesn't count. Go read a comic book or watch the DCAU) now take away the Omega Beams but compensate by making him a giant with a star-splitter ax. Then you have a Dominator.
50,000 years or so ago, the Dominators declared a genocidal war on the universe, or rather the Three Galaxies, and won. All their enemies were dead or quite literally bombed into the Stone Age. Mind, they did sort of lose their homeworld, and most of the population. In fact, there were only a couple hundred survivors who scattered through out the cosmos in their personal Death Stars. What's that? Oh yes, every Dominator ship is moon-sized and planet-blowing up.
The Dominators are vastly technologically superior to everyone in the Three Galaxies, except perhaps the Mechanoids. They live only to fight and conquer and prove their superiority to all others.
On a personal level, each Dominator is ~30 feet tall and 10 tons, they are incredibly tough and strong, with superior senses to a human. They are ageless, virtually immune to psychic powers, but take double damage from magic. Most are armed with a Starsplitter, an ax or halberd that channels cosmic energy to do immense damage and can fire cosmic blasts more powerful than a mid-level Cosmo-Knight. They also have plasma guns as or more powerful than most ships' cannon, heavy MDC armor and "Collector Bubbles" that encase their intended captives.
The apparent agelessness and casual handling of cosmic energy has led many to suspect that the Dominators are in fact the First. Cosmo-Knights consider Dominators a terrible threat, and will drop any lesser quest or enemy to pursue even a rumor of a Dom. The Splugorth hate and fear the Dominators above all others, for they have managed to kill several dozen actual Splugorth, the supernatural intelligences, a feat as yet unmatched by all the heroes and gods of the Megaverse.
That's all I really have for the moment, but I'm pretty sure they get expanded on later.
Whew, and I haven't even gotten to Phase World, Star Hive and the Naruni. Don't worry, they'll be coming up quick. Then when we're clear on who's who and everyone can keep track without a scorecard (and maybe get a couple of classes dealt with) we can get to picking apart ship stats.
