''The Quintaglio Ascension Trilogy'' is a series of science fiction novels written by [[CanadaEh Canadian]] author Creator/RobertJSawyer.

The eponymous Quintaglios are a species of human-like intelligence descended from [[TyrannosaurusRex small tyrannosaurs]]. Though [[IntelligentGerbil similar to humans]], the Quintaglios are true to their ancestry. They are obligate carnivores that hunt with tooth and claw, are fairly aggressive by nature, and have fierce territorial instincts that often turn out to be a major problem when several Quintaglios must work in a confined space (like, say, a ship).

The most interesting twist is this: contrary to most alien species in SciFi, the Quintaglios do not posses highly advanced technology, and are instead at a level comparable to our Renaissance. As the series progresses, this becomes the key source of drama in the plot.

In the first book in the series, ''Far-Seer'', we meet Afsan, an apprentice astrologer. Every Quintaglio goes on a "pilgrimage" to see "the Face of God". Using his telescope (what the Quintaglios call a Far-Seer, hence the title of the book), he learns that the Face of God is actually a planet, and that their world, long believed to be a giant "boat" floating down river, is actually a moon. Of more dire importance, however, is that their moon is too close to the Face of God, and will eventually break apart into a ring. Afsan's claims attract significant attention from Det-Yenalb, the Quintaglio high priest. The Royal family, descended from the prophet Larsk who discovered The Face of God, rules by divine right, and Afsan's discoveries threaten this rule. Afsan's claim that the world is coming to an end also attracts the attention of an ancient cult known as the Lubalites, who believe Afsan to be their Messiah foretold in the Prophecy of Lubal. Afsan must fight to convince his fellow Quintaglios the dire truth, as the fate of their civilization hangs in the balance.

''Far-Seer'' won a Homer award upon its initial release and met with wide critical praise. It was followed by two more books: ''Fossil Hunter'', and ''Foreigner''; Fossil Hunter won yet another Homer award and both were similarly well-received as ''Far-Seer''.

This series provides examples of:
* AxeCrazy: Quintaglios in ''dagamant'', the state where they revert to violent, animalistic territoriality.
* BerserkButton: When their personal space is invaded, Quintaglios enter a stage of animalistic rage known as ''dagamant''.
* BittersweetEnding: [[spoiler: Afsan regains his vision]] near the end of ''Foreigner'', but dies shortly after.
* BlindSeer: [[spoiler: Afsan,]] after having his eyes gouged out by Det-Yenalb for his "blasphemy".
* CainAndAbel: Dy-Rodlox and Dy-Dybo, respectively.
* CallARabbitASmeerp: A telescope is called a "Far-Seer". Also, Tyrannosaurs, Ceratopsians, Ankylosaurs, Hadrosaurs and Sauropods are referred to as "Blackdeaths", "Hornface", "Armourbacks", "Shovelmouths" and "Thunderbeasts", respectively.
* CannotTellALie: Their snouts turn blue whenever they tell lies. Quintaglios that can lie without turning blue are considered to be demonic.
** In Foreigner, [[spoiler: it is confirmed that priests are able to lie. Afsan enlists the help of a priest to help them win against the Others]].
* TheChosenOne: Afsan.
* ColossusClimb: How Afsan brings down a giant sauropod on his first hunt; he shimmies up its neck and bites out its throat.
* CosmicEgg: According to Quintaglio creation myth, God laid the eight eggs of creation at the beginning of time.
* CrystalDragonJesus: The Quintaglios worship the planet their world (its moon) orbits as "The Face of God". It was discovered by the Prophet Larsk (whose descendants are the imperial rulers of their people), which they make a ritual pilgrimage to view. In some ways its more like a fantasy Islam, not Christianity: the prophet, the secular rulers staking their claims to power through relation with him, and pilgrimages. However, it has a clergy which seems more like Catholic Christianity, although they are portrayed as pretty corrupt (they are the only Quintaglios able to lie, for instance), not that this hasn't been the case for the Catholic clergy in certain eras. However, they also have the bloodpriests who kill seven out of eight hatchlings to keep the population under control, which has no real counterpart in either religion (although many cultures have practiced infanticide, just usually not ritually). The discovery that the Face of God is ''merely'' a planet explicitly parallels Galileo. In addition, there's a religion which exists underground at first which was the dominant one before, worshiping the "Five Original Hunters" with a prophesied savior known as "The One". Both religions worship a Goddess that created all things, sacrificed parts of herself to create the Quintaglios, and has Sacred Scrolls as their scripture.
* DoesThisRemindYouOfAnything: The entire series is an allegory for our own age of enlightenment. More specifically, the Quintaglio religion and their reaction to Afsan's discovery of heliocentrism is meant to parallel the Catholic Church's prosecution of Galileo. In the second and third books, Toroca is essentially Charles Darwin, and Mokleb is their version of Freud.
* DumbDinos: The Quintaglios themselves are an aversion, being fully sapient tyrannosaurs.
* EatsBabies: The Bloodpriests. It's usually accepted as a gruesome but necessary job: since each Quintaglio clutch has eight eggs, if all eight hatchlings survived from each clutch the world would soon be overrun, especially given the constant threat of ''dagamant'' in tight quarters. [[spoiler:As it eventually turns out, the Bloodpriest culling is what causes the Quintaglios to be trapped by their territoriality to begin with, because of suppressed trauma from this making them hostile towards each other.]]
* EyeScream: [[spoiler: Afsan]] is blinded with an obsidian dagger.
* FreudianExcuse: Sort of, given that the third book features a Quintaglio version of Freud. The entire Quintaglio species [[spoiler: has been psychologically scarred due to being traumatized by the traditional culling of the Bloodpriests. Being bred for aggression on top of that has resulted in the exaggeration of the Quintaglios' territorial instincts.]]
* GodSaveUsFromTheQueen: Len-Lends was deemed too aggressive of a leader by the bloodpriests, so [[spoiler: they used the royal family as a breeding experiment to try and usher in a new generation of more docile Quintaglios.]]
* HatesBeingTouched: A racial trait of Quintaglios, due to their intense territoriality; most strive to maintain a healthy distance between one another, they must warn anyone who must have hands laid on them (such as an injured person being moved), and casual touching as a sign of affection is virtually unheard of.
* IgnoredExpert
* ILied: In Foreigner, the Other captain says he [[spoiler:won't hurt Afsan if Toroca tells them their weakest point. Upon getting the information, he shoots Afsan anyway]]. When Toroca called him out, the captain chillingly tells him that Quintaglios might not be able to lie, but Others can.
* JerkWithAHeartOfGold: Tak-Saleed.
* KnightTemplar: Det-Yenalb.
* LeaveBehindAPistol: More or less how the murderer in ''Fossil Hunter'' is brought to justice. [[spoiler:In this case, it's a toxic dose of cleaning fluid.]]
* MostWritersAreHuman: WordOfGod states that the reason Quintaglios have so many inexplicable and often counter-intuitive similarities with humans is because he didn't think that readers could empathize with completely alien protagonists, and also that he had trouble getting the first book published because editors thought a series without any humans in it wouldn't sell.
* NamesToRunAwayFromReallyFast: ''Blackdeaths'', aka Tyrannosaurs.
* NoCelebritiesWereHarmed
* TheParanoiac: [[spoiler: Drawtood]] from Fossil Hunter. [[spoiler: He begins murdering his siblings because of the strangeness of having siblings, a concept foreign to Quintaglios, and had no idea how to truly act around them or what to make of them, and at one point described them as being him but not him]].
** In one scene, he wonders if [[spoiler: his sister]] is wishing him dead, as he does her.
* ProphecyTwist
* ReasonableAuthorityFigure: Emperor Dybo is jovial, open-minded, even-tempered, and fair, in stark contrast to the rulers before him. [[spoiler: These dissimilarities to his predecessors were, in fact, the reason he was chosen for leadership: the Bloodpriests hoped he would help create a less homicidally violent generation of Quintaglios.]]
* RecycledINSPACE: The age of enlightenment, [[EverythingsBetterWithDinosaurs WITH DINOSAURS!]]
* RiteOfPassage: To be considered an adult, Quintaglios must partake in at least one proper hunt and be marked with a tattoo.
* ScaryDogmaticAliens: The Quintaglios themselves, prior to ''Far-Seer''. Later, [[spoiler: the Others]].
* ShoutOut: To Moby Dick, via Captain Keenir's obsession with Kal Ta Goot.
* ShownTheirWork: Robert J. Sawyer is a dinosaur enthusiast, and strove for accuracy in the Quintaglio Ascension. Though the Quintaglios themselves stand in a tripod stance, have retractable claws, and can regenerate limbs, this could be attributed to the fact that [[spoiler: they were genetically altered by the Jijaki anyway.]]
* SternTeacher: Tak-Saleed.
* SuicideAttack: Two Quintaglio hangglider pilots make them on Other ships during the battle in ''Foreigner''. One dives her bomb-laden glider into an Other ship, the other crashes, takes hold of a burning ship and steers it into another, detonating its black powder.
* TraumaCongaLine: The reason for Afsan's continued blindness in the third book [[spoiler: despite his eyes regenerating]] turns out to be due to [[spoiler: being wracked by guilt over being chosen by the Bloodpreists over his siblings, his killing Nor-Gampar during ''dagamant'', sadness over the murders of his own children and his guilt over setting up the battle between the Blackdeath and Dybo's siblings. He gets over it thanks to Mokleb's therapy.]]
* TyrannosaurusRex: The Quintaglios themselves are more or less anthropomorphic ''T. rex''es, and a "normal" ''T. rex'' shows up in ''Fossil Hunter'' as a "Blackdeath".
