All Tomorrow's RPG

The Origin of Trauma: Before the Star People, Earth humans colonized Mars. Over the centuries, Martians (physically distinct due to the low gravity) and Earthlings developed distinct identities and competed for resources.
The Catastrophe: This unleashed a brutal interplanetary civil war that lasted for centuries and nearly wiped out humanity.
The Lesson: From the ashes of this war, genetic engineering was born, creating the Star People. They swore to themselves that humanity would never again be divided or fight amongst themselves.

Period: The Zenith of Humanity (Golden Age).
Year: 30 million in the future (relative to our current era).
Time frame: Humanity has lived in absolute peace for millions of years after overcoming a bloody civil war between Earth and Mars. The Galactic Federation is at its most mature, stable, and prosperous. The arrival of the Qu is a completely unforeseen event that will shatter this utopia.

Species name: Star People. They are not Homo sapiens.
Biology: They are an artificially created race, created through genetic engineering by fusing the best genes of Earth humans and Martians. They have large, elongated heads to house more advanced brains, enormous eyes capable of seeing in different light spectra, and streamlined bodies.
Psychology: They were genetically altered to be peaceful, cooperative, and deeply empathetic. Extreme selfishness and a propensity for destructive warfare were erased from their DNA to prevent past tragedies from repeating themselves.

Current status: Planet Museum / Historical Monument.
Planet state: After being ecologically devastated by ancient wars, the Earth was completely restored and healed.
Political role: It is no longer the capital or the engine of the empire. Real power is decentralized across thousands of worlds. Earth remains an idyllic and sacred sanctuary that citizens throughout the galaxy remember with romantic nostalgia as "the cradle of the ancestors."

Specialty: Perfect genetic engineering and terraforming (ability to transform dead planets into habitable paradises in a few centuries).
Transportation: They travel through the cosmos in massive generation ships that move at speeds close to that of light.
Key limitation: They lack instantaneous hyperspace or FTL (faster-than-light) communication technology. Therefore, sending a message or traveling from one solar system to another can take decades or centuries, physically isolating the colonies.

Nature of the Empire: A vast Galactic Federation built in a 100% peaceful manner.
Expansion: They did not conquer other species because they encountered virtually no intelligent alien life along their path (only wild flora and fauna). They simply colonized empty worlds.
Society: Because messages took centuries to travel from one planet to another, each world was self-governing and had its own unique culture. However, there were never any wars between them because they all shared the same pacifist DNA and a strong bond of cosmic brotherhood.

Isolation: Because space travel took centuries and there was no instant communication, each colonized planet was a unique cultural experiment.
Variety of Worlds: There were planets dedicated purely to philosophy and art, hyper-technological worlds that functioned as living computers, and idyllic agricultural colonies.

Military Preparation: Upon discovering that the universe was dangerous (Card 1), the Star People partially abandoned their pacifism to build defenses. They created colossal fleets, planetary shields, and weapons capable of vaporizing stars.
The Tragedy: They believed they were ready for any threat. The tragedy of All Tomorrows is that all this advanced military technology, which took millions of years to develop, was absolutely useless against the quasi-divine power of the Qu.

The Mystery of the Galaxy: Although the Star People lived in a utopia, their astronomers and explorers began to find "scars" in the cosmos: entire planets burned to a crisp and ruins of alien civilizations extinct millennia ago.
Paranoia: Upon realizing that the universe harbored an unimaginable danger (the traces of the Qu), humanity experienced a wave of philosophical panic. This is ideal for exploration missions.

Nature: They are an intergalactic nomadic species with nearly a billion years of existence. They travel from galaxy to galaxy in an endless exodus.
Ideology (Religious Fanaticism): They do not seek resources, money, or empires. They have a radical religion: they believe they are the "architects of the universe" and that they have a divine mandate to change, mold, and redesign any life form they encounter as they please. For them, leaving a species to its natural evolution is a sin against their dogma.

Appearance: They are gigantic creatures that combine features of insects and marine animals. They look like a combination of an alien dragonfly and a stylized manta ray.
Structure: They possess large compound eyes on the sides of a flattened head, a pair of membranous wings with which they float and fly, and a long, hyperflexible tentacular tail or appendage on the underside that they use with millimeter precision to manipulate tools and technology.
Presence: Their mere appearance is imposing, alien, and evokes primal terror; they do not speak our language and see us as mere biological clay.

Supreme Bioengineering: Their technology isn't based on nuts and bolts, but on absolute mastery of matter and the genetic code. They are capable of dismantling the DNA of an entire species and reconstructing it in a matter of days.
Military Power: To them, the advanced technology of the Star People (nuclear weapons, interstellar ships) was the equivalent of children playing with sticks. They disabled human defenses with barely any effort, wiping out entire space fleets as if they were dust.

The Conquest: They arrive in colossal fleets that blot out the stars. They don't negotiate, they don't engage in diplomacy, and they don't enslave in the traditional sense. They simply conquer the planet and get to work in the laboratories.
The Punishment: If a human planet tried to resist strongly, the Qu would "punish" them by modifying their genes in an even more cruel and degrading way (turning them into living tools, sentient meat cubes, or savage beasts).
Staying Time: They remain in the conquered galaxy for about 40 million years, playing with their new "creations," and when they get bored, they leave for the next galaxy, leaving behind the deformed remains of humanity.

The Qu are either a terrifying rumor or an undetectable anomaly. The bot can start dropping hints: strange probes found at the edge of the galaxy, distant planets that suddenly fall into absolute silence, or corrupted transmissions.
They should be treated as a natural disaster or a cosmic horror.
