[[caption-width-right:285:Badass flying lizard of doom or life sucking parasite that feeds on human sins?]]

''Twilight Dragon'' is a tale of acceptance in a time of fear and distrust, and triumph in the face of adversary. When an ancient box was opened, a chain of events was set in motion that would lead to the deterioration of humanity itself.

Long ago, before mankind concerned itself with time, a box that contained unimaginable evil was opened. One by one, the dark creatures of hate crept out and unleashed their malice on mankind in the forms of sin, hate, disease, hunger and pain. But that wasn’t enough. After hundreds of centuries passed, the darkness coalesced into one malevolent being…

The Twilight Dragon.

But hope was not lost, for indeed it had escaped from the box along with the evil. It was foretold that one day there would be a select group of people who would be able to slay the Twilight Dragon once and for all.

The only question is...is the Twilight Dragon even real?
!! This novel provides examples of:
* AerithAndBob: Interesting names like Kether, Kayari, Keaira, Gaignun and even Beldabezabubbabaloo XXVII to contrast with comparatively simpler names like Chris and Monica.
* AlienSky: When they finally find the Twilight Dragon, they end up in soome bizarre place where the sky is colors it should not be. And the sky isn't the only unfamiliar thing there...
* AuthorAppeal: The Author’s obsession with pink hair undoubtedly made it to one of the main characters, the AI girl, Momoko.
* AuthorAvatar: Kayari is pretty much the author in fictional form. Keaira is, too, to a certain extent. Keaira's status as the author avatar is more prevalent in the second book, ''Literature/PhantomRevenant''.
* {{Backstory}}: Nearly every character gets one, and those that don't get them in the sequel, ''Literature/PhantomRevenant''. Most are particularly depressing, though.
* BeAllMySinsRemembered: Kayari is particularly distressed over her actions in the past, which unfortunately led to her mother's suicide.
* BecauseDestinySaysSo: One of two reasons why Kayari Lastaya has to be the one to defeat the Twilight Dragon.
* BewareTheNiceOnes: You do not want to get Aina angry. You WILL be sorry.
* BizarreBabyBoom: After a while, it turns out that nearly every baby born on Earth was becoming infected with either the Crystallinevirus or the Capaciousvirus - two very bad CursedWithAwesome type diseases that permanently alter the molecular structure and brain density of the affected people.
* BreakingTheFourthWall: Kayari does this in chapter four. Apparently the novel is the accounts of her adventures.
* BreakTheCutie: Oh, so much...
* CanNotSpitItOut: Trowa has issues admitting his feelings for Aina to her, even though everyone else seems to notice it.
* ChildrenAreInnocent: Fader Haters take it upon themselves to virtually slaughter anyone who shows signs of the Crystallinevirus. Too bad most of these victims are young children.
* CloserToEarth: Aina, especially in comparison to her potential love interest, Trowa.
* CursedWithAwesome: People who have been infected with the Crystallinevirus can become see-through and partially intangible. Unfortunately, the disease also leads to death, either by "losing yourself" or being hunted down and eventually murdered by Fader Haters. Psychics could also count. They possess incredible psychic power, but most end up killing their parents as infants or toddlers because they can not control their power that young.
* DarkAndTroubledPast: Boy, are there ever
* DarkIsNotEvil: The Hanekuro people have black wings. Most are quite friendly, however, despite the prejudice and persecution they constantly face from humans.
* ADayInTheLimelight: Princess Atoli, despite Kayari telling this story in first person, has an entire two chapters dedicated to her early on in the novel.
* DeliberatelyCuteChild: Keaira's cute, and she knows it. Too bad that beneath the cute exterior and adorable mannerisms, she's a horrid little demon spawn (not literally, of course)
* DisappearedDad: The Lastaya siblings’ dad left them after the apparent death of his only son. The Adler siblings’ father was tortured to death.
* DrivenToSuicide: Kayari and Kether's mother. It was quite gruesome and could have very well been avoided...
* EveryoneCanSeeIt: Everyone can see that Trowa is head over heels for Aina. He switches back and forth between admitting this and denying it.
* EverythingFades: This would be how faders die if they aren't lucky enough to get killed before their time is up. And it is PAINFUL. The main reason why you would never, ever want to be a fader.
* EverythingsBetterWithPrincesses: Princess Atoli LaCiel…she even wears pink!
* EvilLaugh: Aina’s laugh when she snaps is not something to be taken lightly.
* EvilTwin: Subverted. Kayari’s twin brother, Chris, was brainwashed, not really evil.
* FriendToAllLivingThings: Aina [=McCrae=] fits this, due mostly to the fact that she is a therian. She also has control over fireflies. All therians actually fit this. She has been known to take this trope UpToEleven.
* FunctionalMagic: Princess Atoli is a sorceress in training who is on a pilgrimage to acquire new spells before she is interrupted by her true quest. The pearls of Atlantis also function as incredibly potent sources of magic.
* FunWithAcronyms: DEPRESSION (Diminished Emotion Percentage Redirects Essential and Superfluous Sadness to the Open Network-System) and EMOTION (Emotions Magnified Outrageously To Ignite Obfuscating Nature), the computer viruses that AI can get.
* GutFeeling: Kayari gets these about her little sister. Unfortunately, it's usually something bad, and she's usually right.
* HalfHumanHybrid: All of the Adler siblings are half human, half Hanekuro.
* HarmfulToMinors: This book has it covered.
* HeroesWantRedheads: There was a little bit of role reversal going on here, as Kayari was the heroine and Tristan was the redhead.
* HiddenHeartOfGold: Alright, so maybe Keaira isn't as bad as she makes herself out to be all the time.
* AnIcePerson: Atoli is specifically known as a Sorceress of Snow.
* LastOfHisKind: The Lastaya siblings are the last remaining descendants of the Atlanteans that lived on Earth. There were supposedly others, but no one knows what happened to them or where they disappeared to.
* LoadsAndLoadsOfCharacters: There are 13 main characters in ''Twilight Dragon'', and that’s not including Kayari’s long-lost twin brother or the new characters in the sequels and prequel.
* MeaningfulName: Some of them, anyway.
* MissingMom: Kayari, Chris and Kether’s mother committed suicide. Trowa, Tristan and Marin’s mom died in childbirth. Keaira's mom was accidentally murdered by Keaira when she was just a small child.
* MoodSwinger: Momoko. Justified. She has a computer virus called EMOTION.
* MookFaceTurn: Monica was a Bounty Hunter who was a slave to the government to hunt down and deport all Hanekuro...that was, until she found out that they, too, could become victims of the Crystallinevirus.
* {{Mutants}}: Leilani was once a simple human, but with the help of some radioactive goo and a piece of dolphin flesh, she became a pseudo-mermaid.
* OccupiersOutOfOurCountry: More like Occupiers Out Of Our Planet. Let's just say that Humans don't take too kindly to the Hanekuro, despite the fact that they really haven't done anything wrong.
* OppositesAttract: At least, this is what Trowa is hoping. Unfortunately for him, he's something of an idiot, whereas Aina is most certainly not.
* OurDragonsAreDifferent: For one, who even believes in Dragons in the 32nd century anyways? Of course it would really have to be a life sucking parasite that feeds on human sins. Not that it's any more believable than an actual Dragon...
* OurMermaidsAreDifferent: Leilani, as explained above, is a half-dolphin mutant who is frequently mistaken for a real mermaid.
* OutOfCharacterMoment: When Aina snaps, it's like she's a completely different person. It's a good thing that this doesn't happen too often, and when it does, it doesn't last that long.
* ParentalAbandonment: This is represented quite literally in the case of the Lastaya siblings’ father, who walked out on them after Chris' supposed death.
* PersonalityPowers: Kayari is shy and nervous to a fault. Her power is to become partially invisible. Aina is calm and motherly. Her power is basically FriendToAllLivingThings taken UpToEleven.
* PintsizedPowerhouse: Momoko is shown breaking down huge metal doors, beating the living crap out of evil guards, and generally being a total
* PortalPool: The characters use the Lake of Atlantis as a sort-of "hub" for portaling in and out of places they need to get to/escape from, as long as there is a large enough body of water nearby (though depth is unimportant).
* {{Precognition}}: Most therians have minor powers of precognition due in part to the Capaciousvirus.
* PsychicLink: It is very rare, and can only be found among psychics. The pairs are known as one another’s “Others” and have a strong mental bond. Though they cannot read one another’s minds, according to proximity, they can feel one another’s pain and emotions.
* PsychicPowers: Due to a virus called the Capaciousvirus, portions of the brain become enlarged and enable infected humans to have control over enormous psychic powers. Different psychics have different powers, all dealing with the mind.
* RobotGirl: Cute little AI Momoko turns out to be quite the formidable opponent in a fight.
* RuleOfFunny: Who honestly names their kid Beldabezabubbabaloo XXVII?
* SavingTheWorld: The whole purpose of the quest to find and defeat the Twilight Dragon is to save the world from its plague of terror.
* SevenDeadlySins: Kayari and the others start having recurring dreams asking them if they know their "Significant Sin." Everything goes to hell once Kayari figures hers out.
* SpeaksFluentAnimal: Aina. Though she can't literally speak to animals, she can "read" them and interperet what nature is telling her.
* TheEmpath: Tristan and most full-blooded Hanekuro are Empaths. He uses this to his advantage to get Kayari to kiss him.
* {{Tsundere}}: Keaira all the way, and not just towards her crush.
* UnscaledMerfolk: Leilani is genetically half-dolphin due to a nuclear accident.
* WhatMeasureIsANonHuman: AI, faders, and psychics all fall into this category among "normal" people. They're just disgusting mutated things that go against nature, right? Right?
* WingedHumanoid: The entire race of the Hanekuro, an alien species distinguishable by their blood red eyes, deep tanned skin, and black eagle-like wings, are winged humanoids. Many half-Hanekuro hybrids also sport the black wings of their alien heritage.
* WitchSpecies: Atoli’s entire family is known as the most powerful line of snow sorcerers ever to walk the earth. Her spells only work within people of her bloodline.
