Sci-fi/fantasy series (2 quartets, 1 trilogy and one series to come) by Australian author Ian Irvine dealing with the "Three Worlds" Santhenar (setting of most the series), Aachan, and Tallallame, and the four humanoid plus one races living there. Quite gritty and realistic; characters range from flawed to plainly insane. The series is also noted for its seemingly random mix of magic and science, and also large span of events.

The series consists of:
* ''View from the Mirror'' quartet
** ''A Shadow on the Glass''
** ''The Tower on the Rift''
** ''Dark is the Moon''
** ''The Way Between the Worlds''
* ''Well of Echoes'' quartet
** ''Geomancer''
** ''Tetrarch''
** ''Scrutator'' (aka ''Alchymist'')
** ''Chimaera''
* ''Song of the Tears'' trilogy
** ''Torments of the Traitor'' (aka ''The Fate of the Fallen'')
** ''The Curse on the Chosen''
** ''The Destiny of the Dead''
* ''The Gates of Good and Evil''
** ''The Summon Stone''

!!Provides examples of:
* AGodAmI: Jal-nish declares himself God Emperor.
* ActionGirl: A few, notably Irises, once she TakesALevelInBadass.
* ActionSurvivor: With the possible exception of supporting characters like Mendark or [[CoolOldGuy Xervish Flydd]], most of the characters in the series are scribes or engineers, who tend to IndyPloy their way through most situations.
* AndManGrewProud: Over and over again.
* AnyoneCanDie: Ian Irvine appears to take sadistic glee from killing off main characters.
* AntiHero: Oh so many...
* ArtifactOfDoom: The Amplimet
* BabyFactory: The situation is so dire for the Old Humans, that humanity has come to rely on a guild of human broodmares to help sustain the population. Tiaan's mother is one and Tiaan herself is almost forced into this fate.
* BattleTrophy: After a major battle/rescue, ex-scrutator Klarm claims Ghorr's skin as a prize and puts it to good use. He has it fashioned into an effigy that he uses to rally the oppressed people of Santhenar.
* BigDamnHeroes: Averted, after getting captured by Jal-nish, Irsis thinks that Tiann will come up with a plan and fly into the rescue like she always does. Tiann had instead left the area completely and retired to be with her father. Irsis winds up getting decapitated.
* {{Biotech}}: The Lyrinx are masters of this due to their fleshwarping arts. But despite being able to create new life forms and biologically-based magitek items, they hadn't gotten around to being able to cure a dangerous fungal infection.
* BiologicalWeaponsSolveEverything: Averted, the Old Humans discover that the Lyrinx are vulnerable to fungal infection and so they try to bombard the Lyrinx underground cities with it. There's not enough fungus to go around and it's easy to contain the infection if detected early enough, so tens of thousands were infected instead of the whole species. But the idea that the humans were attempting to eradicate them, so alarmed the Lyrinx that they mobilized everyone to wage an extinction war on humanity.
* BlackAndGrayMorality: Even the most upright characters tend to be morally ambiguous anti-heroes.
* CantArgueWithElves: The Aachim are a {{Deconstruction}} and tend to [[NiceJobBreakingItHero screw themselves and others over with their arrogance]].
** ScrewYouElves: Consequently usually turns into a CrowningMomentOfAwesome.
* CharacterDevelopment: Characters do improve over the course of their series. Nish, particularly, goes from being a slimy little git to something of a badass.
* ClockPunk: The level of technology is a mix of Dark Ages Europe and the intricately geared, magically powered clockwork mechanisms. So primitive flying machines exist alongside people using crossbows.
* CookingDuel: A ''story-telling duel'' with the BigBad. Then again, this the only thing Llian does well...
* CompensatingForSomething: Vithis, the impotent leader of Clan Inthis.
* CoolOldGuy: Xervish Flydd. Scrutator, Mage, ManipulativeBastard, and pushing 60.
* CrapsackWorld: Especially under the Scrutators and Lyrinx invasion. Basically the invasions are so devastating that Old Humans face extinction. For that reason, much of humanity has been coerced into factory work, fighting on the front lines or becoming a human brood mare.
* DarkActionGirl
* DeathSeeker: Pilots who lose their control crystals become despondent and even suicidal. This is due to the empathic bond between the pilot and their clankers.
* {{Deconstruction}}: Not a full-on GenreDeconstruction, but it tries to make the fantasy setting more "realistic" (in the DarkerAndEdgier way).
* DownerEnding: The first series had this mildly, the second was horribly depressing. The third series is somewhat nicer but still horribly grim.
* DiabolusExMachina: [[spoiler: Jal-nish coming from nowhere at the end of the second series.]]
* EldritchLocation / DeathWorld: The Void. This is an other-dimensional nexus that is hostile to life and constantly undergoing change. Only those creatures capable of regular physical adaptation can survive there for long. For an idea, the mighty Charon race were reduced to 100 survivors and the Lyrinx were originally human but had to use magic to convert themselves into sphinx-like beings.
* TheEmpire: Old Humans, in the second series.
* TheEndOfTheWorldAsWeKnowIt: Oh look! It's Tuesday. Time for Armageddon.
* FatalFlaw: Aachim and Faellem pride. It is noted by many characters that even the most unbiased and open Aachim Malien is not free of overwhelming arrogance.
* FantasyGunControl: Despite the prevalence of alot of very advanced engineering marvels and {{Magitek}} artifacts, the mightiest projectile weapons are catapults and ballistas (though there was an invention of a {{Magitek}} laser cannon).
* HalfHumanHybrid: Blendings have the blood of two races, triunes have 3 and quartines or[[spoiler:tetrarchs]] have 4. Liable to be riddled with mental and physical problems.
* HoistByHisOwnPetard: [[spoiler: Faelamor. And she takes the rest of her planet and people with her. Her machinations enable her people to travel back to their world, but it had been left open to the Void and ensuing invasions reduced her descendants to regressing into Stone Age primitives.]]
* HumanAliens: The Aachim, Faellem and Charon. For the first two races it's to the point that they are considered part of the human race (regular Homo Sapiens are just considered ''Old Humans''), despite all three coming from other dimensions. And every race can interbreed with each other.
* HumansAreWhite: Averted in the second series. Most of the story takes place in a part of the world where people have an Asiatic appearance, including protagonist Tiaan. Irisis is notable early on for being blonde, blue-eyed and tall.
* IfWeGetThroughThis: * Irisis is the only character who has any definite plans for what she wants to do when the war is over (become a jeweller), a fact which is casually mentioned a couple of times a book. [[spoiler: At the end of the quartet, enter DiabolusExMachina and [[CruelTwistEnding on the second last page of the quartet she dies.]] ]]
* KnightTemplar: The Scrutators in their effort to repel the Lyrinx, spare no human in their goal of defeating the invaders whether it's sending thousands to their deaths in battle or dragooning available women into being brood mares. [[spoiler: It turns out to be a big lie, the Scrutators council had long resigned themselves to the idea of not defeating the Lyrinx, instead their efforts have turned to doing what they can to keep power and indulge themselves.]]
* KryptoniteFactor: The Lyrinx are an unstoppable threat to the humans, but they do have some weaknesses that had been exploited. They fear deep water and can't swim, there's a fungus that is deadly to them but doesn't harm humans, and a sufficiently loud telepathic broadcast will knock them out. [[spoiler: It's the mindcry, when weaponized, that defeated the Lyrinx]]
* LaserGuidedKarma: The evil Chief Scrutator Ghorr loves punishing people with flaying. He meets his end when's he caught in an explosion that blows his entire skin clear off his body. And if that didn't finish him, then falling off the sinking Air Dreadnought and getting impaled on a tree did.
* LoveMakesYouCrazy: [[spoiler:Maigraith becomes obsessed with creating a new "race" by mating her (hybrid) child with Karan's ''as a monument to her dead lover'']]
* MadScientist: Well, Mad Mathematician but its close enough.
* {{Magitek}}: Clankers and most of the other technology are powered as much by magical energy from the planet, as clever engineering.
* TheMagicGoesAway: At the end of Well of Echoes, Tiann fears that the Secret Art's power is too much for any one person. So she globally alters the Nodes that powers the Secret Art, thus cutting off the power for the people and machinery that uses it. This comes to bite humanity back in the ass.
* ManipulativeBastard: Quite a few on both sides.
* MilesGloriosus: Grand Commander Orgestre is the head of the remaining human military forces in Well of Echoes. He loves parading about in military regalia and proudly wears his many medals and accolades on his uniform. Only...he's never been in active service before, he bought his commission as a way to keep out of the frontlines. When he's faced with the possibility of fighting the Lyrinx for the first time, he constantly argued against taking the offensive against them and after a major setback, he leads the retreat while having his underling General Troist do the rearguard. But when the Lyrinx are decisively losing, he's the first and loudest voice to advocate their extinction.
* TheNapoleon: Cryl-Nish, especially painful as his nickname means ''pipsqueak''.
* NotQuiteDead: [[spoiler:Jal-Nish]]
* OurElvesAreBetter: They're called "Aachim" here, but ''boy'' are they pricks.
* ReallySevenHundredYearsOld: All the other races, although Yggur(old human) gets this as well.
* SchizoTech: Everywhere in the second series. Mainly because having been at war for more than a hundred years, all scientific efforts are focused on making better weapons and nothing else.
* SexyDiscretionShot: Quite a few.
* TeleportersAndTransporters / CoolGate: The focus of the first book of the second series is to make one.
* TookAThirdOption: [[spoiler: Rather than force a truce or exterminate the Lyrinx, Tiann transport them to the forest world of Faellem.]]
* TookALevelInBadass: In the time between ''The View from the Mirror'' and ''Song of the Tears'', [[spoiler: Maigraith]] apparently decided to stop faffing about and put her considerable mind and talent to sinister use. [[FaceHeelTurn Not good news]].
** Quite a few lesser examples too, mostly characters who start out as {{Action Survivor}}s.
* TheVamp: Irises starts out as this and a ManipulativeBitch. She [[CharacterDevelopment gets]] [[ActionGirl better]].
* WeAreAsMayflies: Old humans, who are also the weakest race with the least magical talent (most of the time).
* WellIntentionedExtremist: A lot, due to the alien invasions and attempts to save their own species, many characters go all out.
* WhatMeasureIsANonHuman: Used liberally in the second series. It turns out that the lyrinx [[spoiler:are actually old humans]].
* WrenchWench: Tiaan is a master artificer and recreates a piece of technology that eludes the Aachim despite centuries of study. Irisis is one to a lesser extent.
