'''Guardians of the Flame''' is a fantasy series by Joel Rosenberg about a group of roleplaying college students who abruptly find themselves inside the world of their game, in the bodies of their characters. The first book, ''The Sleeping Dragon,'' depicts their attempt to return to Earth, and their later commitment to return. Theater student/[[TheBigGuy huge fighter]] Karl Cullinane vows to end slavery in his new home and persuades his friends to join the crusade. The remainder of the series follows his efforts, and later those of his son Jason.

Karl's colleagues, at least at the start, are history student Jason Parker and football hero Walter Slovotsky (the party thieves), engineering student Lou Riccetti and English major Andrea "Andy-Andy" Andropolous (the party wizards), disabled computer science major James Michael Finnegan (AKA the dwarf warrior Ahira), and Doria Perlstein (the party cleric); the gamemaster is a philosophy professor at the university.

Some of the tropes encountered include:
* AddictiveMagic: Stated explicitly to resemble cocaine addiction - a little bit every now and then is okay, but use too much and it's a steep, quick decline into obsession, madness, and bad hygiene. Demonstrated with [[spoiler:Andy-Andy]], who keeps to a slow, safe, gentle progression, until [[spoiler:Karl]] dies, at which point she takes a [[JumpingOffTheSlipperySlope flying leap off the slippery slope]]. [[spoiler:Subverted in the end - given the choice of sacrificing her sanity or ability to do magic for enough power for an epic spell, she chooses the latter. She does, however, display symptoms of catastrophic cold-turkey withdrawal afterward.]]
** This may be the entire motivation of [[spoiler:Arthur Deighton/Arta Myrdhyn]].
* AnAdventurerIsYou: Each of the students becomes an archetypal role-playing hero, complete with the abilities and limitations appropriate to their level and class.
* AnotherDimension: The fantasy world that the students are sent to (and later returned to) in the first book.
* AnyoneCanDie: ''And how!'' Usually, one significant character per book bites it, but the biggest one has to be when [[spoiler:Karl, the central protagonist of the series so far,]] sacrifices himself so the rest of his motley crew can escape a trap in the fourth book. Other hugely important deaths include [[spoiler:Jason Parker,]] [[spoiler:James/Ahira, although he got better,]] [[spoiler:Rahff Furnael,]] [[spoiler:Chak,]] [[spoiler:Baron Zherr Furnael,]] [[spoiler:Tennety,]] [[spoiler:Mikyn,]], and [[spoiler:Durine]].
* BerserkButton: James/Ahira's feelings toward his handicap, condescending people, and the name "Jimmy" from anyone except Walter Slovotsky.
* TheBigGuy: Karl Cullinane in his warrior persona. Also Walter Slovotsky, football player/party thief, in either persona ... big, beefy, and too good-natured to dislike.
* DefiledForever: Doria's view of herself after [[spoiler: covering up a teenage sexual experience, which then left her sterilized by an STD that was treated too late]].
* EarnYourHappyEnding: Big time. In the course of their quest to return to Earth, [[spoiler: two of the students are killed, two are raped (with one becoming catatonic), and all but one are captured by a slaver that they have to fight free of. And then they have to go back to resurrect one ... yes, that's right, just one ... of the fallen heroes and wake the catatonic one, with part of the price being Lou giving up magic, Karl agreeing to fight slavery for the rest of his life and Doria passing into the care of her clerical order for the forseeable future.]]
* FantasyGunControl: Subverted from the third book on, when engineering student Lou Riccetti works out how to recreate gunpowder weapons and give the fight for freedom a big edge. [[spoiler: It becomes an arms race, though, after the bad guys figure out a way to create a magical equivalent to gunpowder]].
* GameMaster: Dr. Arthur Deighton, philosophy professor, is a longtime GM who has this great new campaign he wants to try ...
* GladiatorGames: Subverted, in that the Great Games of Pandathaway are not a sentence for slaves but actually a means for fighters to earn a few coins in between jobs. Participants can become quite wealthy if they fight well, or bet well.
* GreatBigLibraryOfEverything: The Great Library of Pandathaway, which makes the similarly-named one of Alexandria look sick. However, actually finding anything there can be quite expensive, especially if the librarians take a dislike to you.
* HesJustHiding: Performed in-universe with [[spoiler:Karl]]. His friends know that he's almost certainly dead, but they hold out hope, in part because he's such a powerful symbol for the resistance.
* HumansAreBastards: How Ellegon has come to view humanity after having been drugged, captured and forced to incinerate sewage for the last 300 years to keep himself from drowning in it. After his liberation by Karl, subsequent books find him modifying his views, saving his wrath for the slavers.
* IceCreamKoan: Slovotsky's Laws, an ever-growing list of Walter Slovotsky's humorous (and often accurate) observations about the world around him.
* IChooseToStay: James Michael Finnigan, after getting the chance to leave his crippled body and become the dwarf warrior Ahira.
* MadeASlave: At one point, the party is captured by slavers intent on revenge for an earlier humiliation. Also part of the origin story for many of the people who are freed and/or recruited by Karl's band.
* TheMedic: Doria attempts to avert this trope -- she's sick of playing the healer, she wants to *do* something. She only agrees to play the cleric after winning the power to approve the others' characters, but gets conned into letting them all play who they want anyway.
* MontyHaul: Averted. The GM tries to give the characters a big pile of magic items at the start to make the quest a piece of cake, but a panicky Lou accidentally blows them up with a Lightning spell.
** Not quite his fault, he'd been told at the gaming table to prepare one 'just in case' due to the shift in starting points, suffered a head injury when they were transposed and just let loose with the lightning bolt due to his confusion.
* NeverLearnedToRead: Though all the main characters are literate in English, everyone except the wizards and cleric finds themselves unable to read or write the language of their new home. As early as book two, this has been corrected [[spoiler: except for Jason, who is killed early in book one]].
* OurDragonsAreDifferent: Ellegon, a young dragon who is fiercely devoted to Karl and deathly afraid of bows, despite his near-invulnerability, thanks to [[spoiler: a poisoned bolt he was shot with as a child]].
** More specifically, dragons in this world are the typical extremely powerful western wyrms, save that they cannot afford to harrass humanity too directly because of a deathly allergy to a common herb named dragonbane which can be used to poison missile weapons.
* OurDwarvesAreAllTheSame: Ahira, who pretty much follows the fantasy archetype [[spoiler: with the possible exception of his inability to swim, due to a racial density that is greater than humanity's]].
* PowerLossMakesYouStrong: Lou Riccetti actually becomes more dangerous ''after'' [[spoiler: losing his wizardly powers and being forced to rely on his engineering skills]].
* PrimeDirective: Utterly averted - at least in the first four books, none of the main band even stops to think if it's ethically or morally justified to introduce huge changes into the sociopolitical culture of another world[[note]] of course considering that this is ''slavery'' that will probably be practiced for many more centuries absent intervention and they did make an effort to establish a better system...[[/note]]. For example by introducing guns which triggers an arms race and trying to end slavery by violent assualts on slaver caravans rather than waiting to see if it comes about naturally as society evolves past the need or allowing of slavery. Not to mention setting up their own ''kingdom'', forever changing geopolitical makeup of the world. Possibly justified by the fact that Arthur Deighton/Arta Myrdhyn had already seriously interfered (including fighting a massive magical duel that laid waste to an entire valley) though it's not made clear whether he's an earth or world native.
* RapeAsBackstory: [[spoiler: After being captured by slavers, Doria the cleric and Andy-Andy the novice wizard are gang-raped. Doria, who already had [[DefiledForever issues in her past]] goes catatonic; her treatment by the Healing Hand is the beginning of her truly accepting her clerical status. Andy-Andy, meanwhile, helps Karl and Co. get even over the long run.]]
* RedStringOfFate: Karl and Andy-Andy. In later books, it's revealed that [[spoiler: the wizard who sent the students across was actually waiting for Andy-Andy to join the group, since she and Karl were fated to have a child who had the power to wield a particular artifact]].
* TheResistance: Karl and his friends decide to oppose the local slave trade and thereby set themselves up as this.
* SpellBook: A subplot in the first book, after Lou/Aristobulus [[spoiler: accidentally destroys the spell books for himself and Andy-Andy, meaning they both have to conserve their spells until they can find a way to acquire or create new ones.]]
* SquishyWizard: Played straight in the first book: Lou's wizard, Aristobulus, is elderly and frail, and neither he nor the younger Andy-Andy have any weapons or weapon training. In later books, Andy-Andy breaks with the trope and begins learning some useful combat skills.
* ThrowingYourSwordAlwaysWorks: Demonstrated and subverted at a crucial moment in the Great Games of Pandathaway. [[spoiler: The sword misses completely, but distracts the other fighter long enough for his opponent to close with him and grapple instead.]]
* TrappedInAnotherWorld: Karl and his friends have no easy way to return to Earth, short of finding a gate guarded by the world's oldest, strongest dragon.
* VancianMagic: All wizards and clerics in Rosenberg's world work by this rule, needing to either memorize spells or pray for them each day. This causes huge problems when the party's most experienced wizard [[spoiler: accidentally destroys his spellbooks]] while the party's sole cleric [[spoiler: is unable to regain her spells through prayer because she no longer believes in a benevolent deity]].
* WeHardlyKnewYe: [[spoiler: Jason Parker]], one of the original party, is killed off very early in the first book to hammer home how dangerous the situation is.
* YouFightLikeACow: Subverted. Early in the first book, Karl starts to make a quip after cutting off an opponent's hand ... only to get grabbed from behind by another combatant in mid-joke. [[LampshadeHanging Lampshaded]] as Karl thinks to himself "You stupid idiot. You know better than to chat while a fight's going on." Only the timely arrival of Ahira with a crossbow keeps him from getting his throat cut.
