Garden of Evil: The Blight, a slowly-expanding disease on the land that spans the northern side of the main continent, where every plant and 'animal' is poisonous, extremely deadly, and out to get you. Thanks a lot, Aginor. Its expansion ceases to become an issue after the first book. At it's heart lies Shayol Ghul, the physical point that is closest to the weakness in the Dark One's prison.
Even in the twelfth book it's an issue, they just don't obsess over it as much. Rand spent a whole chapter going up there and seeing just how far it's expanded.
Gender Bender - More than one character speculates that the Dark One must have a sense of humor after he reincarnates the infamous, womanizing Balthamel as a woman. Although extremely upset at first, she soon gets used to the change and becomes a manipulative Vamp. It helps that Balthamel's new body is a particularly alluring one.
Genetic Memory - Mostly early in the series, particularly with Mat, who curses at the Aes Sedai in the Old Tongue during his intensive Healing session. Not to be confused with the soldier/general memories that get crammed in his head later, which are Eelfinn-related. The chivalrous Genetic Memory of Manetheren is also suspected to be a contributing factor to his Wouldn't Hit a Girl tendencies.
Genius Bruiser: Rand. In addition to being the most powerful channeler ever born, a blademaster, and a superhuman Warder, he also demonstrates great skill in the Game of Houses and outplotting his enemies. When he isn't putting Honor Before Reason in really stupid ways, that is. In the second book, he's suddenly thrown into Cairhienin politics and, despite being from a quiet farming background, manages to outmaneuver the nobles long enough for help to arrive. Solid.
Mat is an even better example of this than Rand. After two minutes of studying the map, he comes up with the same battle plan as half a dozen veterans working together. When his back is to the wall, he kills the leader of the other side's army in single combat. The genius part comes from the training and experience that comes with memories from other men given to him in a mystical deal, and the bruiser part comes from practice with a quarterstaff as a sport.
Genre Savvy: Justified in-universe; see other mentions of ta'veren on this page. More than once, Aes Sedai who want to find certain characters who happen to be ta'veren do it by listening for rumors of really weird stuff going on, the kind of coincidences that happen around them all the time because they are Main Characters. In The Gathering Storm, the reverse happens: an Aes Sedai experiences a succession of extremely unlikely events, and realizes it means destiny must be pushing her towards a ta'veren.
Mat, after his first trips to Finnland becomes the living embodiment of this trope. His head is full of memories from other ta'veren and thus he can draw upon those memories to know nearly every outcome of any skirmish that occurred in history. He uses this trait to great advantage. Sooner in the serie, he also gained unbelievable luck, but it also comes with hearing the sound of dices rolling every time something big is going to happen, as if he was, let's say, a character in a tabletop game waiting for the GM to roll the dice. It pisses him off every time.
Mat, again, during his second trip to Finnland uses all of the knowledge from other stories about the place, as well as the game built around it, to learn both how to cheat and that he must cheat the system to beat the snakes and foxes.
Gentle Giants: The Ogier. Well, the Randland ones, anyway, most of the time. The Seanchan variety are called "Gardeners"... of the 'pruning a few limbs' variety.
Get a Hold of Yourself, Man!: All over the place. Expect the mains to give and receive at least a couple of these per book. For example, Rand gets an epic one from Sulin in Lord of Chaos after he leaves his bodyguards behind when teleporting:
“The great and powerful Car’a’carn gave his honor to Far Dareis Mai to carry,” she all but hissed in a low whisper. “If the mighty Car’a’carn dies in ambush while the Maidens protect him, Far Dareis Mai has no honor left. If the all-conquering Car’a’carn does not care, perhaps Enaila is right. Perhaps the omnipotent Car’a’carn is a willful boy who should be held by the hand lest he run over a cliff because he will not look.” -Ch. 19, "Matters of Toh," Lord Of Chaos
Girlish Pigtails - One of the Wise Ones threatens to do this to Egwene if she doesn't stop acting so childishly(!). And she carries it out, too.
Giving Up On Logic: Mat quickly does this in Towers of Midnight when he, Thom, and Noal journey to the world of the Eelfinn and Aelfinn.
A Glitch in the Matrix — Happens a lot in the World of Dreams, but they are only rarely serious enough for visitors to notice. There is a good chance that the average reader will miss glitches.
God - Entirely off-page. Anti-God, Dualism-style, is the Big Bad. It's implied in some ways that the Creator's powers are greater, since he was able to imprison the Dark One, but for whatever reason he's apparently unable to directly affect the world in ways the Dark One can.
Another possible interpretation is that the Creator IS the Dark One's prison, and that the reason neither normally affect the world is because the Creator uses all of his power to negate whatever the Dark One tries to do, and if he took any of his power away from the prison to do something, the dark one would be able to apply equivalent power at the same time. Which brings up the question: Does that mean that the Bore is a hole in GOD?
God Emperor - It is implied that Lanfear's plan was to overthrow the Dark One and set herself and Rand up as God Emperors using the unlimited power of the Choedan Kal.
Go Mad from the Revelation - The test for becoming an Aiel chief involves passing through a ter'angreal that causes them to relive key moments in the culture's history. Aiel place such emphasis on honor that the shameful truth of their origins — they betrayed the oath they lived by — hits hard. Rand enters at the same time as a real Aiel, and by the end the other man is clawing out his own eyes. (Rand has a rather unfair advantage here, since he wasn't raised as an Aiel.) Rand later reveals the truth to everyone, and hordes begin to defect from the old warrior lifestyle every day, either vanishing altogether, joining a rogue tribe, or returning to the pacifism which their culture started with.
Good Is Not Nice - Cadsuane, the Aes Sedai in general, the Aiel, and Logain. Rand is also a prime example and says so himself. The latter ultimately subverts this later.
Good Hurts Evil - Rand, after coming to terms with his existence in The Gathering Storm, has the power to passively negate the rotting and corrupting influence of the Dark One and no Darkfriends can meet his eyes without visible difficulty. When he actually uses the Power and goes all-out, he sent a couple insane at the Light that he emanates.
Good Parents: Many of the characters come from genuinely loving families.
Rand specifically attributes his better qualities and ability to work through his Heroic BSOD to the good upbringing and parenting of his adoptive father, Tam. And although she died when he was very young, Rand's memories of his adoptive mother, Kari, are just as positive.
Gossip Evolution - Used frequently. Several books end like this, with an omniscient narrator describing gossip versions of the main event of the book. The narrator mentions several contradictory versions of the big epic battle but one important, portentous detail that all the different rumors agree on. Something similar happens in-story several times as well, where side characters hear twisted versions of events of the story as rumors, sometimes even things the characters they are talking to were present for. The rumors are usually wrong on important details, and the viewpoint characters are usually happy to know that their role in the real events remains obscure.
Grand Finale: The final trilogy of books, The Gathering Storm, Towers of Midnight, and A Memory of Light, which lead directly up to and include the Last Battle. In fact, this was all supposed to be one book when Robert Jordan was writing it, with the name of the latter of the three titles (even if it required a new kind of library cart), but upon his Author Existence Failure, Brandon Sanderson decided that the sheer amount of plot threads that he needed to tie up meant he would need a trilogy, which includes a great increase in intensity over previous volumes.
Great Way To Go: During the Last Battle, the Borderlanders start doing this for all their dead to try and keep morale up once Lan starts it.
Green-Eyed Monster: If Perrin so much as looks at Berelain, Faile practically turns green.
Green Lantern Ring: The One Power has enough potential uses to quallify it for this, considering that it helps drive time and existence itself. It does, however, have its limits, as does the True Power.
Nynaeve is infuriated that the Kin are helplessly deferential to the Aes Sedai despite being technically independent and in many ways more learned. She endeavours considerably to get them to collectively "grow some backbone" and stand up for themselves, and they gradually do... to her, which is not remotelywhat she intended.
Rand, initially over the course of the first book when he stands up to the Amyrlin Seat at the start of the second.
Grim Up North: The Blight, the Blasted Lands, and Shayol Ghul. See Garden of Evil above. Subverted after the Dark One is sealed away at the end, with normal plants finally growing there.
Several of the Forsaken are very fond of this. Especially Ishamael.
Nynaeve delivers one to the Aes Sedai at the conclusion of her test in Book 13, when they were about to fail her for losing her calm and stopping to help children when she was supposed to let them die.
Happily Adopted: Rand genuinely loves his adopted father and gets over his "is-he-or-isn't-he-my-father" angst regarding Tam al'Thor relatively quickly, concluding that Tam is his father no matter what their blood relation is or isn't.
In the most recent book, he even attributes the fact that he's able to successfully pass through his Heroic BSOD to the good upbringing Tam gave him.
Rand: "My father is Tam al'Thor. He found me, raised me, loved me. I wish I could have known you, Janduin, but Tam is my father."
Rand's adoptive parents, Tam and Kari al'Thor, certainly counted as this prior to Kari's death. So much so that even fifteen years later, Tam still hasn't remarried, instead devoting all of his time to raising their son and tending the family farm.
Harmony Versus Discipline - Women must use Harmony to channel saidar, men must use Discipline to channel saidin. While both can achieve pretty much identical results, trying to use the method of the opposite sex is disastrous and potentially fatal.
Happens around Rand all the time, due to his transient ta'veren effect. In Rhuidean, this prevents Mat from using his luck to make an important decision.
In book 13, Mat rolls two six-sided dice and gets a one: one of the dice landed on its corner.
Head-Tiltingly Kinky: "The Nine Horse Hitch" is the name of an inn; Siuan is too embarrassed to explain the meaning of the name; and nothing else is revealed about it.
It seems obvious; the Inn is named for a...ahem...well-endowed man. As in, a regular "hitch" can only hook up two or three horses.
Henpecked Husband: Just about every married man, to some degree. Ebou Dari wives wear knives to slice up or murder their husbands when they misbehave, and Saldaean couples tend to resolve their differences through shouting matches. The latter's a subversion, since it's supposed to prove that the husband isn't henpecked, and is also taking his wife seriously.
Perrin was this before Faile's kidnapping, and while he now stands up for himself the way she has been wanting all along, he occasionally slides back.
Hero Killer: Demandred waits until A Memory of Light to fight directly, but he takes down Gawyn, Galad (nonfatally), and very nearly Logain and Lan before being killed by the latter.
Hero of Another Story: The books show that everyone is a hero in their own story on the side of the Light. This is flat out stated in Book 14.
Egwene's Spirit: Am I not allowed to be a hero, too? [...] You march to your death. Yet you forbid anyone else from doing so? [...] Let go, Rand. Let us die for what we believe, and do not try to steal that from us. You have embraced your death. Embrace mine.
Not just on the side of the Light; it's hinted in the last book (and confirmed by Word of God) that Demandred was essentially the hero of his own parallel version of The Wheel of Time in Shara.
Heroic Sacrifice - In the second book, Ingtar doing his last stand vs the Seanchan army, to let the others escape. The sacrifice of Verin in the twelfth book is much quieter but no less heroic.
Arguably the most significant sacrifice is Moiraine. Books 12 and 13 however reveal that she's Not Quite Dead, though her 'sacrifice' did take out Lanfear for quite a while.
Book thirteen has another, fittingly enough connected to undoing the previous one: Noal Charin. It, along with many other things in his life, result in it being so heroic he is made a Hero of the Horn,
Book 14 features many of these. Gawyn and Egwene die of these, while Lan and Galad do not.
He Who Fights Monsters - Mordeth. Rand, too: as his sanity started slipping, he became increasingly determined to harden himself in order to do what must be done; characters around him in turn become increasingly terrified of what he is becoming and what might happen if he fought the Dark One in such a state.
Subverted with Rand at the end of book 12 when he learns to laugh again.
Hide Your Lesbians - Quite a few minor female characters are "pillow friends". One pair even get blackmailed for it, though the blackmailers are astonished that this would succeed as there are no prejudices against homosexual relationships (it was more that one participant was terrifed of her husband finding out). See Situational Sexuality.
Debatable whether or not this should be classed as this trope simply because the term 'pillow friends' is this world's name for lesbians, the word 'lesbian' doesn't occur.
Hijacking Cthulhu: You have the a'dam, a slave collar that lets certain (mostly normal) women control Chanellers. This means someone below a novice can control the strongest possible chaneller if they have them captured.
In a hilariously magnificent move, Mat recruits the people of Hinderstap (cursed to go into a murderous frenzy every night, only to be revived in the morning) in the Last Battle, thus using the Dark One's evil against him.
Graendal is about to use her signature technique, Compulsion, on Aviendha when an exploding gateway backfires it onto herself.
Holding Back the Phlebotinum - Rand never takes full advantage of his Asha'man forces, each man a walking weapon of mass destruction. He could easily wipe out the Seanchan before they ever knew what hit them—with surprise attacks if nothing else, as male channeling cannot be directly detected by females and techniques that don't cause huge explosions are always an option. The parody says it best:
Bashere: There are reports of a huge Seanchan army with hundreds of damane advancing towards Illian. You command over a million soldiers, and hundreds of Asha'man. Rand: I will take 5,000 soldiers and eight Asha'man. Bashere: It should work. With your mediocre planning and surrounding yourself with those who hate you, once again, you should just barely avoid complete disaster.
It is argued that Rand withholds his Asha'man forces for good reason - lack of trust, possibility of them going off the rails mid-combat (after the Cleansing, though, perhaps not so much.), keeping them in reserve for the Final Fight, not wanting to lessen the amount of people available to fight the Shadow, a battle between damane and Asha'man could easily result in the effect of a small nuclear bomb...
Holier Than Thou - The Children of the Light, and many Aes Sedai. Also the Seanchan.
Holy Hand Grenade - Egwene's Dying Moment of Awesome might be the closest approximation, the opposite of Balefire, repairing its damage to the fabric of reality... and turning a huge chunk of the enemy forces into crystal statues.
The Horn of Valere fits even better. A magical relic of unknown origins which summons dead heroes back from the grave to fight. First blown by Mat in book 2 to help defeat the Seanchan invaders. In the Grand Finale it is blown by Heartwarming Orphan Olver in order to save himself from the Shadowspawn who have him trapped.
The Aiel are a curious example. An extremely rigid system of honor defines the Aiel, so to them Honor is Reason.
Hopeless War - The War of Power for the forces of the Light, the Trolloc Wars until Maighande.
The Aiel War was also pretty hopeless for the non-Aiel. The combined might of every nation between the Mountains of Mist and the Spine of the World, the Aes Sedai AND the Whitecloaks was only able to "win" because King Laman died in the final battle, which was all the Aiel really wanted. Not to mention that only a fraction of the Aiel actually went to fight the war.
Horse of a Different Color - The Seanchan have torm (cross between a cat and a lizard), raken (small dragons) and to'raken (larger dragons).
The raken and to'raken are more pterosaurs than actual dragons, though.
How Do I Shot Web? - Remarkably, instead of everyone becoming instant channeling masters, it takes a good three or four (or seven) books for the main characters to get a real grasp on channeling, with a lot of spectacular failures in the interim.
Human Weapon: The Asha'man are trained this way, to use their channeling for hugely destructive purposes, because of a dire need to get powerful soldiers in time for the Last Battle, but also because the price of their power drastically shortens their lifespan. Rand's instruction to the man placed in charge of the Black Tower is, "Make them weapons." He later changes his mind, sending in a messenger to tell them, "We're not weapons. We're men." This has its part in causing them to rally around him.
The Void, the dark nothingness outside the Pattern that is used for Skimming. Infinite for all practical purposes—-if you fall off the tiny platform you're on, you will either die of starvation, dehydration or fear.
Hypocritical Humor - Here and there, and Nynaeve takes the cake, especially in book 5. Example:
What she did not quite understand was why she liked Areina best. It was her opinion, putting this and that together, that nearly all of Areina’s troubles came from having too free a tongue, telling people exactly what she thought. [...] Nynaeve thought a few days of herself for example would do Areina worlds of good. -Ch. 49 "To Boannda," The Fires of Heaven
Also Mat complaining about Olver's behaviour with women
I Am Not Left-Handed - In his fight against Eamon Valda, Galad deliberately holds back for most of the fight.
I Am Who? - Rand searches for the identity of his birth parents and is surprised by the results.
If I Can't Have You - Lanfear says this to Rand al'Thor when he tells her that there isn't a chance in hell he'll ever love a Forsaken.
I Know You Know I Know - Rand knows that the Wise Ones must know that he knows that they're trying to spy on him with Aviendha.
Also pretty much the definition of the Game of Houses
I Know Your True Name - Moridin uses his "mindtraps" to gain absolute dominance over Moghedien and Cyndane, turning them into his personal slaves as long as he holds the objects tied to their souls.
I Like Those Odds: Birgitte tells Mat that the odds of getting back from the Tower of Ghenjei are one in a thousand. Mat responds by taking out "two dozen" coins and predicting that when he throws them every single one will land heads up (1/16,777,216 chance if there were exactly 24). They do, and Mat remarks that "One in a thousand is good odds, for me."
I'm Not a Hero, I'm... - Mat. Often when he gets into trouble, he is quick to remind the reader that he is "no bloody hero!"
I Need a Freaking Drink - Considering that Birgitte, Min and Aviendha can all feel what Elayne does when she was knocking boots with Rand, it's entirely justified that these three decide that there isn't enough booze in Caemlyn to deal with this but figure it's worth trying.
Mat's reaction when he finds out Birgitte's true identity. Her agreeing with him is the start of their friendship.
In Name Only: In-Universe, this is how the Amyrlin Seat's position as "Watcher of the Seals" for the seals on the Dark One's prison is viewed, especially in Book 14, where this trope is brought up by name. Until very recently in the books, the seals had been missing. By the time of Book 14, when Egwene, the Amyrlin, confronts Rand about his proclamation that he is to break the seals, says that she is their Watcher... despite not even having them, and talking to their owner.
Insane Troll Logic: There's a fair share of this wandering around the westlands, partially due to Gossip Evolution. For instance, the appearance of the Dragon Reborn is a signal that The End of the World as We Know It is nigh. Therefore, there are people who genuinely believe that if you kill The Dragon Reborn, the world will not end! What could be simpler!
Intimate Healing - After chasing someone into a blizzard, Rand has to do the "naked body warmth" variety. The person being someone who had been fighting her attraction to him, One Thing Leads To Another, and this particular woman had teleported herself into a blizzard precisely to avoid that.
It May Help You on Your Quest: At one point Thom notes that Mat is given everything he needs even if he doesn't realize what he needs it for at the time. It's quickly attributed to his unbelievably good luck as a Ta'veren.
It's Not You, It's Me: Rand takes this approach toward not only his love interests, but his father and hometown as well. The possibility of his enemies discovering his attachment to any of them is one of his greatest fears, so Rand purposely distances himself in order to protect them.
Jerkass: Egwene seems to be the only character never called out for it (and never to reflect on it, despite her bullying of Nynaeve from book 4 onward, her condescension towards Mat and Rand, and her judgmentalism towards Moiraine's tactics.
Rand doesn't bat an eye at the countless good men who die for him (or because of him), but Semirhage of all people goes onto his little list of self-punishment?
This changes after his little epiphany at the end of The Gathering Storm. He recognizes the idiocy in that and compiles a mental list of every single person who has ever died in his name or because of his actions.
Jossed - The theory (with plenty of arguments) that Demandred is masquerading as Taim ("Taimandred"). Even the two pieces of evidence in Winter's Heart that contradicted this were not wholly believed until Jordan finally settled the matter personally. Some still believe he changed it out of spite.
Kangaroo Court - In Book 4, Siuan is on the receiving end of one of these courts, led by Elaida. Although all of the Sitters were handpicked by Elaida in order to get Siuan deposed, stilled, and executed, the rebel Sitters insist on claiming that what was done was legal, as Elaida had the bare minimum of Sitters required. Later, we find that some of those Sitters were Black Ajah, which invalidated the whole proceeding. Not to mention one of the Forsaken.
Katanas Are Just Better - The original blademaster's sword Rand gets from his father is similar in design, as the officially-licensed collectible replica demonstrates. Taking it even further, Mat gets a Blade on a Stick called an ashandarei, a possible Expy of the Japanese naginata (though it also resembles a European glaive, or a Polish war scythe) or the Chinese Guan Do, which is associated with several famous Chinese generals and more than one God of War.
Kissing Cousins - Zigzagged with Rand al'Thor and Elayne. Rand finds out that his mother was Tigraine and becomes worried that he is related to Elayne, since both Tigraine and Elayne's mother Morgase were noblewomen in Andor. He traces his family back, and is horrified to learn that Tigraine and Morgase were cousins which leaves him Squicked out. However, it turns out that Morgase and Tigraine were not actually closely related, and "cousins" is just a term for other noblewomen in Andor who descend from the same general bloodline, and Rand and Elayne are not really closely enough in blood to make a difference. However, while her family line is too distant from his to really make a difference, Tigraine and Morgase both descend from the same long-dead queen many generations back, meaning that Elayne really is Rand's cousin, albeit a very distant one. Also, they have a mutual half-brother, Galad, who is the son of Rand's mother and Elayne's father.
Kiss-Kiss-Slap - Rand's relationship with his three girlfriends. Other relationships in the series gravitate between this and Slap-Slap-Kiss.
Klingon Promotion - One of the two ways to become a Blademaster is by defeating an extant Blademaster in fair, one-on-one combat. Rand and Galad become Blademasters in this way.
Knife Nut - Mat carries enough knives to impress the Aiel. Faile carries so many knives that Perrin worries about stabbing himself by accident if he hugs her. Min packs more knives then might be necessary too.
And of course, we can't forget Thom, who was not only performing fancy knife tricks, but using them to kill enemies with contemptuous ease, right from the first book.
Lady Killer In Love - Mat, not that he'll admit it although it seems his feelings have been manipulated by the universe in order to achieve his destiny, considering the woman is a veritable enemy with few redeeming qualities.
The only person who managed it was made a Forsaken purely on the basis of being able to do that. He was mediocre at just about all of the other things the folks on the dark side do, but that accomplishment was so impressive that he got recruited to the inner circle of team evil, and took up Shadowspawn breeding full-time.
Given the importance of the Shadowspawn to the Shadow's strategies, Aginor (the aforementioned Forsaken) is undoubtedly one of the most useful members of that group. The others were generals and spies and demagogues. Aginor built armies that would plague the world long after he was sealed.
Living Crashpad: With Born Lucky Mat Cauthon, who once killed an attacker by intentionally throwing himself off the roof while grabbing with them. He landed on top and the other person died in the impact.
Living Legend: Many, if not most, of the characters. Most apt would be Birgitte Silverbow, a Hero of the Horn, who is now wandering around the real world again.
The Ta'veren Power Trio - Rand, Mat, and Perrin - have literal, justified in-universe Plot Armor, so they can tell fate to go fudge itself. The distaff Power Trio - Egwene, Nynaeve, Elayne, and Aviendha - are particularly strong channelers, who have discovered long-lost or completely new weaves. Min has a completely unique prophetic ability. Most of the above, and several other characters as well, have become politically important leaders over the course of the story, except for some who started out that way. Basically, the only people who don't qualify are the people Jordan doesn't see fit to mention.
Loophole Abuse: Aes Sedai take this trope and not only run with it but they manage to take the family farm, get elected as Mayor and take over the Women's Circle. The main reason that people don't trust Aes Sedai is that they'll make a promise or statement they have no intention of keeping and just find ways around it, they are very good at this. This bites the Black Ajah in the ass when Verin exploits a very obvious loophole in their secrecy clause by posioning herself to pass on the identites of all the Black Ajah she's been able to uncover.
It's hard to believe anyone could be quite as dumb, complacent and arrogant as he seems, especially in a court like he comes from, but on the other hand he's been around for at least half the series and still has yet to reveal any hidden depths, so...
Weiramon: Excellent plan, my liege. Shall I charge at the opposing army? Rand: No. That’s a corn field. —Isam's snarky summaries
Book 13 confirms that he's a Darkfriend, which might explain some of his idiocy.
Lost Technology - Rare remnants of the Age of Legends that draw on the One Power. Angreal increase the amount of power that can be safely channeled by a person. Sa'angreal are far rarer and more powerful versions of angreal. Ter'angreal, however, were each designed to do a particular thing and hence vary hugely in their function; some don't even require channeling to activate. The original purposes of most are largely unknown, and attempts to discover their purposes are extremely dangerous. Known ter'angreal include the Oath Rod, items allowing access to the World of Dreams, a nigh-impossible-to-control balefire rod, various portals to other dimensions, Magic Bane and magic detection items, portable wards against evil, the Choedan Kal's buffered access keys... (Ter'angreal figure prominently in the game.)
