Page-bottom layout change on the way. Details here.
Causes no change to editing/formatting of articles. This is just FYI.
are a staple of a great many Sci Fi
settings. While Precursors come in many different varieties, the defining aspect is that they existed in the time before a setting's contemporary civilization.
Recursive Precursors occur when the concept of Precursors
is applied recursively
; such beings served a similar role to Precursors as they do to contemporary civilizations. The odds are surprisingly high that Precursors to these Precursors had even had another
race that served as their own Precursors
, and so on, forming a long line of ancient civilizations.
Of course, having a long series Precursor
races carries some disturbing implications
. Beyond the fact that Precursors existed in the time before the setting's present civilizations, another important aspect of Precursors
is that they are no longer around. Perhaps it is In Life's Nature to Destroy Itself
. Perhaps they were wiped out by their creations
—bonus points if those creations went on to become Precursors
to another young civilization. Maybe they were wiped out by an unrelated group of Precursor Killers
. Or maybe they were Sealed In Some Sort Of Can
. Less pessimistically, it's possible they've just ascended to a higher plane of existence
, died out for mundane reasons, or simply left the immediate area for whatever reason.
Naturally, this is a Sub-Trope
. When Creating Life
is involved, this trope is highly compatible with Recursive Creators
, but is otherwise not related to other "Recursive Tropes" such as Recursive Reality
and Recursive Fanfiction
Anime and Manga:
- In Gall Force: Eternal Story, the Solnoids are the precursors of humanity; in Gall Force: Stardust War it's also revealed that the Solnoids also have precursors. Finally, in Gall Force: New Era, it's revealed that due to a Stable Time Loop, all the races in the story are each other's precursors.
- Lyrical Nanoha has Al-Hazard, which served as the Precursors of the Ancient Belka empire after Al-hazard destroyed itself, which in turn served as the Precursors of the current setting after Ancient Belka destroyed itself.
- In the Star Wars Expanded Universe, there are multiple races of Precursors, starting with the Celestials, who created the hyperdrive triangle which makes galactic civilization possible. After them came the Rakata, who built a massive Empire, created the basis for all hyperdrives, and left behind things such as The Star Forge. Contemporary with them were the Gree, who among other accomplishments built the infrastructure that makes Coruscant's planet-wide city possible before withdrawing to a handful of worlds where they survived until the 'present' of the series.
- Babylon 5: Lorien and the rest of his kind were this to the other First Ones, like the Vorlons and the Shadows.
- Battlestar Galactica: The People of Kobol were Precursors to the People of Earth and the 12 Colonies, but there was presumably no one before them unless you count whatever "It" is that doesn't like being called "God" and the Head People.
- In Doctor Who, we have the Eternals, some of which were apparently the seldom mentioned gods of Gallifrey; Precursors to the Time Lords who are themselves (sometimes) cited as the reason for there being so many races of Human Aliens, Rubber-Forehead Aliens, and Humanoid Aliens in the Whoniverse.
- In Red Dwarf it is speculated that all life in the universe originated on Earth, with humans acting as Precursors to countless other races, who in turn acted as this to even more sentient creatures.
- In the Stargate Verse, the Goa'uld were originally thought to be the ones who had built the Stargate network, come to Earth to find slaves, and built the Pyramids to land their spaceships. SG-1 quickly discovers that while the Goa'uld were indeed the ones on Earth thousands of years ago, the Stargates were actually built by their precursors, the Ancients, millions of years ago. Stargate Universe revealed that the Ancients had found signs of their own Precursors (or God), but the series ended before they could be revealed.
- The Star Trek Expanded Universe is full of these. There's all the uberpowerful noncorporeal life, and the ancient humanoid preservers, and a hundred or so other ancient powerful empires.
- In Greek Mythology the first major figures are Gaia and Oranos, whose children were the Titans, many monsters, and the Gold race of men who died out by not reproducing. Then Cronos, the leader of the Titans, castrated Oranos and overthrew him, then Cronos' kids overthrew him (yeah, they've kind of got a children killing their parents theme here). Also Zeus created the Silver race of men, but they were too warlike and he had to destroy them, so Prometheus made the Bronze race who were our ancestors. Then the Olympians wiped them out with a flood, but Prometheus' son Deucalion and his wife Pyrrha survived by floating in a chest. Zeus took pity on them and told them to throw stones behind them. The stones thrown by Deucalion became men, and the stones thrown by Pyrrha became women.
- Norse Mythology is kind of similar, with Odin and his brothers killing the primeval giant Ymir, making the world out of his body, and instituting the rule of the Aesir.
- In Warhammer 40,000, Eldar are a borderline example of a Precursor Race, in which case their creators, the Old Ones, would qualify as well, alongside the Necrontyr/Necrons, and the C'tan Star Gods.
- Forgotten Realms elves dominated Faerun before they torn both continent and their civilizations apart in Crown Wars, which left them weakened and gradually displaced by human expansion, all the while Dwarven and Giant kingdoms still fought each other. But the Elves in turn took the world from Dragons' claws. That's where we switch from merely mythical era to the Time Abyss of Creator Races about whom little is known: Dragons fought giants after knocking birdlike Aearee out of Toril's sky... Aearee in turn spread when Batrachi got themselves extinct, before their time there were Sarrukh and Fey, and so on. And before that was "Time of the Rauth" — prehistorical era when something was going on too, but what is completely lost by now.
- Eberron has a long history of being ruled by demons, then dragons, then giants, then goblinoids (in Khorvaire), then finally the common races. Some of them are still around to some extent, from the Dragons of Argonessen to the Demon Wastes to whatever is happening in the depths of Khyber.
- Traveller Gurps Alien Races 3 discusses this as an optional alternative for lore about The Ancients. However the normal canon does not discuss this much.
- Precursors of the contemporary object of worship—"The Maker"—in the Dragon Age series were the seven Old Gods of Tevinter. Their Precursors were the nine Elven gods ("Creators"), and their precursors were the Forgotten Ones.
- In Homeworld, the ancient Hiigarans left their hyperspace core to be discovered by their descendents 3000 years later. But the Ancient Hiigarans never built the core, they found it. It was made by a still older race known only as the Progenitors, who, according to legend, are said to have originated from beyond the galaxy.
- The Mass Effect universe has a bunch of these, one of which–a Reaper called Sovereign–provides the page quotes. Of course, due to the Law of Conservation of Detail , only two of these races–the billion or so year old mechanical Reapers and the 50,000 year old Protheans, respectively the first and last in the line of recursive precursors–are relevant to the plot.
- Javik reveals that the precursors to the Protheans were the Issuanon, who's ruins on Ilos were where the Prothean first discovered Mass Effect technology, much like Humans had from the Prothean ruins on Mars.
- Towards the end, it is even considered that the Citadel Races might become the Precursors for the next generation of galactic species.
- In the Extended Cut, one of the options at the end is Refusal — revolted by the Catalyst and its options for ending the war, Shepard refuses to fire the Crucible. The united fleets of the galaxy are vanquished by the Reapers and all sapient, spacefaring life in the galaxy is harvested (again). However, the epilogue shows one of Liara's time capsules (which she mentioned compiling earlier in the game) being discovered and explaining to an unknown species the cycle of extinction, the Reapers, the Crucible, and the story of Shepard's war. In the final scene, an alien speaker explains to a child how, through the help of those who came before them, they were able to defeat the threat of the Reapers.
- And just to top everything above, in the Extended Cut of ME3, the Catalyst reveals that the Reapers had their own precursors, who also created him as means to solve the organic-synthetic conflict. His monologue implies that said precursors looked more or less like a organic version of the Reapers and were (not entirely voluntarily) harvested into the very first Reaper (believed to be Harbinger in the lore).
- In the "Leviathan" DLC, Shepard can meet some of the eponymous species, which created the Catalyst (and by proxy, the Reapers). Uncounted millions of years later they're still bitter about it, but after seeing so many cycles go by, they've become too scared of the Reapers to aid the species. Shepard's goal becomes convincing them to aid the current cycle and stand up to the Reapers. They're still very much Abusive Precursors, but they understand that the Reapers can not be allowed to go unchecked anymore.
- The Dead Space games have an almost identical overarching scenario: The Brethren Moons scattered Markers throughout the galaxy. When a civilization finds one, the artifact will compel them into worshiping it or attempting to replicate it (since it's a source of unlimited energy). The Marker triggers a Necromorph outbreak which eventually culminates with Convergence, the creation, of a new Brethren Moon out of countless Necromorphs. This is what happened to the natives of Tau Volantis, it's currently happening to humanity, and it's probably why space is dead.
- Halo's Forerunners had the preceding species Precursors, who were rumored to have exceeded technology and become transentient. By the time of the Flood invasion, many believed the Precursors were legend, unaware that they had defeated the Precursors millennia before and the Flood was their revenge. Literally, as Precursor corpses broke down into a dust that, centuries later, would become the Flood.
- In the Star Control series, the first Precursors we know of is the race that left behind the massive battleship that the Ur-Quan use, who themselves Turned Against their Dnyarri slavemasters, who themselves had killed their own Precursors, the Sentient Milieu. The reason for the original Precursors not being around anymore was eventually revealed in (the often-ignored) Star Control III ; they were wiped out by an Even More Advanced race, possibly their own Recursive Precursors.
- The Freespace series has some in-universe speculation on this. The Ancients were the Precursors to the modern-day Terrans and Vasudans, but they were wiped out by a total enigma of an advanced species called the Shivans, who are now attacking the Terrans and Vasudans. One character speculates that the Shivans have been around for a really long time, and exterminating any civilization that evolves to a certain point like they did the Ancients, though there is no direct evidence that this is the case. Some Word of God statements about the never-made third game implied that the Shivans themselves are an engineered species, so that would be another Precursor race who did the engineering.
- The aliens from Escape Velocity Nova known only as Those Who Came Before merged with the universe millennia before humanity achieved space travel. The epilogues to four of the storylines mention that humanity followed in their footsteps several thousand years later, becoming precursors to another alien race.
