->''It's the world on the other side of the mirror, the world that pretends to look like ours, that behaves while you're watching it, that's watching you when your back is turned. Wonderland is the world that exists in empty places where no one can see it. It's the universe that's up and about at 3:00 AM. It's twisted and hungry and it knows all about you. It's read your mail, your diary, and your mind. It has your single, missing socks. It's eaten your sister. It's awakening across the globe and getting stronger. Wonderland is what you should be afraid of, instead of the dark.''

Imagine Lewis Caroll meeting Creator/HPLovecraft.

''JAGS Wonderland'' is a tabletop setting for the free generic RPG JAGS. In it, a bizarre, inexplicably contagious mental illness known as Cyclic Psychoaffective Disorder is sweeping the world. The psychological community and most governments refuse to acknowledge CPD as [[TheSchizophreniaConspiracy anything more than normal Schizophrenia.]] A few conspiracy theorists insist there must be more to it, but nobody believes them.

They really, really [[CassandraTruth should.]]

In reality, CPD is not a mental illness. In reality, there are seven lower [[LayeredWorld layers of reality (called "Chessboards" individually and "Wonderland" collectively by those who know about them) beneath the one we inhabit]], and once in a while someone [[DownTheRabbitHole accidentally falls through the cracks]] becoming Infected (or ''Unsane'', because they are not losing hold of reality, '''reality''' is losing hold of '''them'''), and periodically being returned to Wonderland against their will. While on one of the lower chessboards, they throw a [[ADarkerMe ''Reflection'' (an irrational copy of themselves) up onto our world]] (''Chessboard Zero'') that tries to imitate their actions on the lower levels to the best of its ability. If it can't copy them, it freaks '''out''' (''Dissassociation''). Worse yet, once one finally makes it back up to reality (usually taking a few hours and finding their Reflection has done something embarrassing or illegal) the native creatures of Wonderland can follow them back up (''Notice''). While in Wonderland, one can be mutated (''Twisted'' or ''Damaged''). Most people who are Infected die or vanish into thin air within a year.

[[WorldOfChaos Chessboard One]] looks like the real world, for the most part, except that the people living there (''shadows'' who directly reflect one person from Chessboard Zero) act very strangely, going about their tasks in very roundabout ways, and all spoken or written communication expresses exactly what the speaker subconsciously meant, rather than what they said. Chessboard One also serves as the entrance to the [[InnBetweenTheWorlds Linear Maze, a strange environment that connects all the other Chessboards to one another.]]

On [[DarkWorld Chessboard Two]], there are still shadows, but only a fraction as many. The parts that aren't directly used by shadows tend to be nearly-deserted, twisted places that look like they came from [[Franchise/SilentHill a certain little resort town]]. The deserted areas are home to monstrous manifestations of the dominant impression of the area on Chessboard Zero, known as [[Literature/WhereTheWildThingsAre Wild Things]], that have no direct analogue above.

On [[CloudCuckooLand Chessboard Three]], the world is nearly unrecognizable, becoming a strange mix of Victorian cities, Medieval countryside, and representations of bits of the mass subconscious (for example, a shopping mall might become a cathedral dedicated not to any god, but the idea of Consumerism). The Wild Things are pretty common here.

On [[DreamLand Chessboard Four]], small suburban towns dot the confusing, dreamlike landscapes of the mind. Things like expectations and ideas are actual physical substances that can be pried from the land. Wild Things are everywhere.

At the [[EldritchLocation very lowest layers]] live the [[EldritchAbomination Caretakers]], some of whom Alice and Lewis Carroll met, others who they had the good fortune never to. The Caretakers really don't care for reality, because it operates on mathematical principles and they operate on literary ones. [[OmnicidalManiac They especially hate (or love, for certain values of the term) mankind]], the one thing that can actually understand the rules. In the 1960s, after extended [[FirstContact contact]] with a shadowy organization in the US Government, the Caretakers decided something needed to be done. They ultimately decided that the [[DriventoSuicide most effective way would be to simply tear apart humanity's will to live]]. This they accomplished by creating a series of projects that could go up to the levels just beneath Chessboard Zero and bedevil any shadows they find. Foremost among these are [[GovernmentDrugEnforcement Big Pharma]], the official initiative supported by most Caretakers, which seeks to pervert psychiatric medicine to [[DespairEventHorizon eradicate all hope and free will]], and [[TheMenInBlack Project Pagan]], a Caretaker-controlled [[GovernmentConspiracy conspiracy within the U.S. Government]] to twist humankind so thoroughly that they will become [[TheGreys something the Caretakers can work with.]] A few others try to make [[DealWiththeDevil Faustian bargains with the Infected]] [[TheMole in exchange for exposing]] [[ZombieInfectee more people, with the goal of infecting the entire world.]]

What they don't know is the very lowest level, full of machines that keep the other levels working, could render them [[AscendToAHigherPlaneOfExistence obsolete if humans ever understood what the machines were for.]] Which they will. Soon.

However all is not lost. The remains of the agency that made first contact with Wonderland, called Project Pilgrim then and Project Puritan now, [[{{Masquerade}} crusades to keep Wonderland as hidden as possible, in the hopes that if the infection is contained, it can be controlled.]] Those Infected who survive for long enough and don't throw their lot in with the Caretakers wage a desperate struggle to get by. And most hidden of all, the Magicians, who learn to control Wonderland without entering it, and who each choose any of a number of different allegiances.

!!JAGS Wonderland uses the following tropes:
* AnimateInanimateObject: Some of the Caretakers, such as the Factory and the Wheel.
* AscendToAHigherPlaneOfExistence: [[spoiler: What will happen to humanity once (''not if, once'') they deactivate the Department of Works, the universe sized machine in Chessboard Seven that keeps reality going.]]
* AttackOfThe50FootWhatever/ IncredibleShrinkingMan: A gameplay mechanic. It just wouldn't be Wonderland without it. PC's and NPC's can be anywhere from an inch to a hundred feet tall, made that way by various sources. [[spoiler:Specifically, the Typeist can [[EnforcedTrope enforce]] this on others.]]
* BodyHorror: A common element, and frequent component of becoming Twisted. Upon entering Wonderland, people who feel powerless in life may become NoodlePeople. Gamblers and risk-takers may gain a prehensile neck. People who suffer from some form of self-loathing may be run through with metal blades and barbs. The list goes on.
* BedlamHouse: Just a few [=InNetwork=] Physicians can turn any mental hospital into this.
* BrainInAJar: [[spoiler:One of the formerly-human heads of Project Pagan. It's getting impatient with Pagan's slow progress, and is contemplating just wiping the unconverted mass of humanity out with nuclear weapons.]]
* BreakingTheFourthWall: ''Wonderland'' starts with Alice introduce the game to you. In MindScrew way.
-->''"I suppose you think you’re reading about me while I think I’m dreaming of you, but we can’t really be sure who is dreaming of whom and who is reading of whose dreaming…''
* BrownNote: The Llamed strain.
* ClapYourHandsIfYouBelieve: Inverted. By enforcing the notion that anything you see during an episode is [[AllJustADream absolutely one hundred percent not real,]] Underground support groups can slow or even halt the progress of infection. They believe themselves to be blunt realists who are DoingInTheWizard by refusing to embrace delusion; this belies the fact that Wonderland is [[DoingInTheScientist indeed very much real.]] Due to Infection originating from seeing and believing in an Impossible Thing, seeing and ''not'' believing weakens it. If it were possible to totally "unbelieve" in Wonderland, an infectee could be cured instantly.
** Ironically, this method is effective only as long as the support groups don't realize ''why'' it's effective -- If it were explained to them, they would know for a fact that Wonderland is real, and would be unable to disbelieve. And on it goes...
* DarkerAndEdgier: Than the [[Literature/AliceInWonderland source material]] to be sure.
* DeadlyDoctor: The [=InNetwork=] Physicians. They're created when the need to mentally dominate a patient takes over a psychiatrist from one of the lower levels of reality. They enjoy tormenting their charges a little too much.
* DownTheRabbitHole: In-universe slang for a deep trip [[spoiler:to the lower levels of reality, where the Caretakers live.]]
* DrivenToSuicide: [[spoiler:What the Caretakers hope to achieve on a worldwide scale with the Big Pharma project.]]
* EarnYourHappyEnding: It's going to be hard, it's going to be painful, many are going to die. But in the end, [[spoiler:humanity's victory over the Caretakers and Wonderland is not just likely, it's predetermined, a mathematical inevitability. Humanity ''will'' find the Department of Works in Chessboard Seven, destroy it, and transcend as the true master of everything and nothing.]]
* EldritchAbomination: The Caretakers. [[spoiler:Somewhat subverted in that they are ''absolutely '''terrified''''' of us, since while it ''is'' possible for us to figure out their rules, [[HumansAreCthulhu it's impossible for them to figure out ours]].]]
* EvilChef: They're really more like KnightTemplar Chefs, but Confection Cooks (Whirls produced when someone feels an overwhelming sense of anger towards a KarmaHoudini) use their pastries to bring about poetic fates for their targets. Unfortunately, they're also rather LawfulStupid...
* EnemyCivilWar: Between the 'true' Caretakers and the [[DeconstructedTrope Deconstructionists]]. No, really. Since the Caretakers embody literary concepts, naturally the ones who embody taking those tropes apart are their natural enemies. They're just as bad a lot of the time, but they're more likely to help you.
** Some of the Caretakers also work at cross purposes to each other.
* FateWorseThanDeath / AndIMustScream: Some Caretakers want to "civilize" humanity. This is the result.
* FlatEarthAtheist: The Support Groups refuse to acknowledge that the experiences they go through are actually happening. [[spoiler:At least not the Lower Echelon...]]
* ForTheEvulz: The Army of No was meant to ''punish'' humanity, not just destroy it. Which means their Caretaker sponsors gave them a sense of humor that is best described as [[EvilIsPetty maliciously petty]]. Such as specialized devices for destroying [=iPods=] (so they can remove the music that gives you joy), and television bugs that force the most grating, annoying ads through your media devices (so they can laugh at your frustration). It's even part of their official SOP for keeping the troops entertained.
* ForTheLulz: The Cheshire Cat will do anything for his amusement, never let things settle down if he can “turn the heat up”. He can be helpful, but his help usually sends you from frying pan into the flame.
* FullCircleRevolution: It's basically stated that [[spoiler: if the Deconstructionists win they'll be just as bad as the Caretakers - the StealthPun here is that they would pull a DeconReconSwitch.]]
* GovernmentConspiracy: Project Pilgrim, set up by the government to combat the spread of Infection, and Project Pagan, set up to [[spoiler: turn humanity into something the Caretakers can tolerate.]]
* TheGreys: [[spoiler:The result of Project Pagan's attempts to turn humanity into Rational Actors.]]
* TheHeartless: Whirls, Shadows who were spliced off from the people who cast them in the grip of strong, usually negative emotion. The [[PsychoPsychologist InNetwork Physicians]] are the [[TheUsualAdversaries variety that is usually the most antagonistic]], but the others aren't nice either.
* HumansAreSpecial: Aside from the automated Department of Works, humans are only ones that are capable of understanding math, something the Caretakers can't.
* LittleGreenMen: [[spoiler:The original "aliens" produced by Project Pagan. Very few humans were intelligent or megalomaniacal enough to be converted, thus the focus was shifted to turning people into TheGreys.]]
** The Field Martians of the Army of No, too. They actually don't claim to be from anywhere but Earth (the name is a reference to the [[WarGod god known also as Ares]]), but they are indeed green, [[MarsNeedsWomen and they are lustful]].
* LovecraftianSuperpower: Like Alice, you may get a serpent's neck and loose sight of your feet. Or other things... [[spoiler:Unlike most examples, however, the Twists are not due to corruption of yourself, but exposure to Wonderland allowing you to manifest [[PersonalityPowers bits of your subconscious]] as mutations. They're actually vital to fighting the Wild Things, and they're quite temporary.]]
* NiceJobFixingItVillain: At some point in the distant past, the Caretakers managed to damage the machines. This caused the breaching between Chessboard Zero and lower layers. [[spoiler:Unknown to them, it all went according to the Department of Works's plan. Now it's only a matter of time before humans discover the machines.]]
* PersonalityPowers: If you end up falling DownTheRabbitHole, you tend to walk away from the experience with powers that shape themselves to your personality and traumas. Getting the attention of the Caretakers can have this effect as well, but their rather warped perspective tends to make their alterations... [[BodyHorror unusual.]]
* PuttingOnTheReich: The Army of No, intentionally.
* RuleOfDrama: In Wonderland these have replaced the laws of physics.
* SecretProjectRefugeeFamily: The Lost Family, who fell into the hands of an [=InNetwork=] Physician, escaped, and now work with groups around the country to fight their influence and try to rescue people trapped in the lower Chessboards.
* SexySecretary: Andrea, the Secretary of the Army of No. She uses a poisoned stiletto to clean her nails, so it might not be a good idea to hit on her too much, unless it takes the form of a humiliating bribe to get an appointment with her boss.
* ShoutOut: Watching ''Music/{{TheWall}}'' is specifically noted as a good way for an infected individual to slip down a few levels.
* TheMadHatter: Oddly enough, the trope namer doesn't count in this version--in fact, no one is quite sure what the Mad Hatter thinks, because he's trapped in a strange mini-reality where it's always Thursday afternoon.
** You can get a Mad Hatter Reflection with the Cool Reflection perk, though.
* ThePowerOfHate: The Wheel claims to run on self-hatred, which he considers to be a universal force instead of an emotion. [[spoiler: He's also the Caretaker behind the aliens, who were originally humans that have been stripped of all emotions except hatred.]]
* WickedWitch: The [[ExactlyWhatItSaysOnTheTin Wyches]], Whirls born from the realization that one is obeyed because he is feared rather than respected. They are, as their nature would suggest, purveyors of BlackMagic (actually techniques to call up Wild Things from the lower Chessboards) and vicious bullies. Hell, an effect they exert on Zero is literally Halloween decorations and B-Movie occult symbols showing up everywhere!
* WhiteMansBurden: Parodied with the White Rabbit's Burden, the twisted feeling of responsibility some Caretakers have for mankind.
* WorldOfPun: Wonderland seems to run on puns almost as much as it does the RuleOfDrama. General Ledger of the Army of No constantly demands '''more reports!''', the Army itself has long divisions instead of regular divisions and field martians (who aren't from Mars), the Liebrarian presides over a library filled with untruth, the Typeist is constantly infuriated by humanity's inability to stick to her categories...
