Describe ''[[VideoGame/{{Exile}} Exi]]''-- I-I mean ''Avernum'' here.

''Avernum'' is a series of computer {{Role Playing Game}}s by [[http://spidweb.com/ Spiderweb Software]]. There are currently six parts in the series, as well as ''Blades of Avernum'', which [[GaidenGame doesn't directly influence the plot]]. The first three games, and ''Blades of Avernum'', are actually remakes of the popular ''VideoGame/{{Exile}}'' series of games--and are rightly awesome. The fourth, fifth and sixth, however, are completely new games, with a completely new engine.

The games follow the adventures of several groups of, well, [[AnAdventurerIsYou adventurers]]. In the first, they are just a bunch of misfits cast down into the depths of Avernum, which is the name for a humongous series of caverns... and the only place the Empire does not rule, instead casting down its undesirables into it via a one-way magical portal. In the second game, the heroes are a band of soldiers in the Avernum army, accidentally getting a big role in the war against the Empire and diplomacy with an alien people. In ''Avernum 3'', the protagonists are the "secondary" team sent to the surface, after the first group disappeared without a trace. ''Avernum 4'' features another band trying to discover the source of numerous problems (mostly of the monstrous variety) which have sprung up after a period of peace. ''Avernum 5'' puts you in the shoes of soldiers from the Empire, now at peace with Avernum, trying to hunt down a particularly nasty rebel who wishes to end that peace. The final game in the series, ''Avernum 6'', casts you as Avernite soldiers desperately trying to stem the chaos of an Avernum overcome by both a Slithzerikai invasion and the Blight, a disease destroying Avernum's food supply.

''Blades of Avernum'' happens after ''Avernum 3'' and doesn't follow the exploits of Avernites per se. In fact, it does not have any cohesive, overarching plot at all. Instead, it lets you [[GameMaker create your own scenarios]] and [[GameMod play the ones other people have made]]. Unfortunately, it has been all but abandoned by Spiderweb Software. However, there is still a community of designers for it and [[http://www.truesite4blades.com/ several dozen scenarios]] have been produced, some of which are very good.

''Avernum'' is being rewritten ''again'', starting with '''Avernum: Escape From The Pit'''. The main reason behind this is that the first series (Avernum 1, 2, 3) doesn't run well or at all on modern [=OSes=] (especially {{Macintosh}} 10.6 or above), and the programmer wants to use a better looking engine. As well as porting the game to the iPad.

----
!! These games provide examples of:

* AllCrimesAreEqual: Not fitting in is a crime, and, depending on the mood of the judge, can get you executed or thrown into Avernum.
** Also, towns will try to kill you on sight if you get caught committing any crime from mass murder to petty theft. Sometimes even simple tresspassing will suffice.
* AllInARow
* AlwaysChaoticEvil: Used straight and subverted. Demons in particular with ''very'' few exceptions (read: not violently hostile) are this.
* AdaptationExpansion: What ''Avernum'' is to the ''VideoGame/{{Exile}}'' series.
** In turn, the latest rerelease of the first game adds more to the original game yet again (especially an extended tutorial intro), much like how the first ''Avernum'' polished and refined the gameplay from the first ''Exile'' game.
* AndroclesLion: If you're lucky, freeing a trapped animal will get it to help you. If you're unlucky, it'll just try to eat you.
* AnEconomyIsYou: Averted. Shops either have junk mixed in or only show you what you want to see. Plus, they probably sell their best stuff to Avernum's army instead of you.
* AnimalWrongsGroup: In ''Avernum 5'' there is the Circle of Life cult which breed various nasty critters and release them back into their (newly settled) natural habitat, much to the displeasure of others. However when the group is confronted it is shown that they are quite pacifistic.
* AnimatedArmor: Doomguards.
* AntiGrinding: Fairly well-implemented. You get very little XP from killing monsters far below you in level.
* AnvilOnHead: In the first game, 'X' is trying to research a spell that literally does this. [[spoiler: By the last game, he perfects it.]]
* AuthorityEqualsAsskicking: Generally played straight, as various leaders of both the good and evil persuasions (Hawthorne, Garzahd, the Triad, Erika, Rentar-Ihrno) are quite powerful, almost always magically. General Baziron in the third game is a something of a GameplayAndStorySegregation subversion. His description notes that he's clad as a Dervish, one of the Empire's elite soldiers, but that he's only entitled to because he's a great general and it's a sign of honors bestowed upon him, not because he's a mighty warrior. The game, however, has him as a Dervish, so if you pick a fight it turns out he really is a reasonably good ass-kicker.
* AutomatonHorses: ''Avernum 3''.
* BagOfSharing: Averted. Everyone has their own inventory, and you have to be adjacent to pass stuff along in combat.
* BareFistedMonk: Kinda. In ''Avernum 3'', in the endgame, characters are so powerful that they easily reach the weapon damage cap of 200 points. However, there is one weapon which doesn't have a cap--fists.
* BarrierChangeBoss: A few minor bosses in the second trilogy.
* BeneathTheEarth: The setting, except for ''3'' and ''Blades'', most of which take place on the surface.
* BigBadEnsemble: [[TheEmperor Emperor Hawthorne III]], [[EvilOverlord Sss-thsss]], and [[spoiler:[[{{Satan}} Grah-Hoth]]]] in ''1/Escape From the Pit''.
* BladeOnAStick: Preferred weapon of Sliths.
* BlockPuzzle: A few times in the first three games, usually done with [[CrateExpectations crates]]. Unusually, rather than getting them out of your way, you have to move them onto specific floor tiles without accidentally pushing them into the water (particularly difficult in the second game's aptly named "Test of Patience.")
* BookcasePassage
* BookEnds: In ''Avernum 4'', one of the first side caves you enter near the beginning of the game is dead-ended by three squares of cave-in. Much later, you find that the other side of that cave-in was a hideout of endgame-level mountain giants.
* BossInMookClothing: ''Constantly'' in ''Avernum 5''.
** Normal Sliths are pretty fair mid-level mooks. Slith ''warriors'' and ''shamans'', however, are in a league all their own. The warriors have ''way'' more health than anything at their level should have, are ''ridiculously'' hard to hit, and possess powerul attacks. Oh, and they can knock back ''and'' ensnare. Shamans, meanwhile, have even ''more'' health than the warriors despite being mages, spam summoning spells that will always summon a top tier monster (such as Revenants), and are almost always encountered with a small army of normal Sliths and Warriors. Oh, and they're both highly resistant to fire spells, which, at the point in the game you start encountering them, are pretty much a mage's only offensive spell.
* BottomlessBladder: Eating is only necessary to rest to regain HP, which is a change from the ''VideoGame/{{Exile}}'' games. If you want to just walk around to regain HP at a slower rate, that's fine too. Not to mention healing magic... This is [[AvertedTrope Averted]] in ''Avernum 6'', though. Due to the Blight, food is at a premium and malnourishment commonplace. To drive the point home, your characters will automatically eat food in their inventory at regular intervals. If there is no food in the inventory, they will be affected with a hunger debuff that reduces their abilities until they next eat. Thankfully, food is easy to come by.
* BrainwashedAndCrazy: In ''1/Escape From the Pit'', [[spoiler:the enemy Slith turn out to be this, having been corrupted by dark magic following [=Sss-Thsss's=] pact with Grah-Hoth.]]
* BreastPlate: One of the player character avatars looks like Comicbook/RedSonja, complete with chainmail bikini. One of the male avatars is also scantily-clad, and the Sliths and Nephils wear nothing but loincloths. Of course, the pictures don't necessarily reflect the gameplay.
* BrickJoke:
** X and his anvil spell.
** Early in ''Escape From the Pit'', Legram is something of a warmup boss helping your party get accustomed to combat. You can face Legram again much later in the game; you find that [[spoiler:in the meantime he's suffered a HumiliationConga where he's been rejected not only by Avernum, but also [[TruceZone the freehold of Kyass]] and even [[WretchedHive the cities of the Abyss]]. He tried to set up his bandit nation in the no-man's-land between Fort Saffron and Fort Spire, only for his base to get destroyed by eyebeasts. You're basically there to put him out of his misery.]]
* BucketBoobyTrap: The illustration for the "Tool Use" skill in the first three games. Naturally, the bucket is labeled "acid."
* CallForward: In ''Escape from the Pit'', completing a quest for for the talking spider tribe rewards with an unusually thin cloak and strange, shuriken-like blades. Veterans of the series will recognize these as Vahnati equipment.
* CameBackWrong: Crystal Souls are [[AndIMustScream rocks that can't so much as move on their own]]. Most of them aren't bonkers, but the ones that are tend to be ''impressively'' nuts. In the games you only deal with a handful that CameBackWrong, a few with post-traumatic stress disorder, and some that just don't like you. There are also the ones who are happy to chat, but they're less exciting.
* CatFolk: The Nephilim are a furry, feline race renowned for their sharp senses and ability to see in the dark.
** And the Nepharim, their stronger, infertile, cousins.
* CerebusSyndrome: A relatively mild case since the humor was always somewhat black. Installments after ''Avernum 3'' became darker and more serious, much like the tone of ''VideoGame/Geneforge''. Note this is also when PhilFoglio stopped illustrating the menus.
* ChaosArchitecture: Mostly justified. Avernum sees a lot of seismic activity -- not to mention that the first exiles didn't have much to work with when they built everything in the first place -- and [[spoiler:the Tower of Magi gets destroyed by demons]].
* CityGuards: They have a special statistic which makes them triple-effective when fighting against {{Player Character}}s.
* ClimaxBoss: Sss-Thsss in the first game, as well as Rentar-Ihrno's [[spoiler:first]] fight in the 4th game. Though the fact that you still have a third of the map to explore might spoil this one.
* ConvectionSchmonvection: In the original trilogy and ''Blades of Avernum'', stepping in lava deals a large amount of damage, but standing next to it is fine. Later games, counting the remake of the first game, simply make it impossible to walk over.
* {{Cult}}: In ''Avernum 3'', you can even join your choice of either anti-magic nutjobs or Creator/AynRand-inspired libertarian fundies. Then there is the Cult of the Sacred Item, which more or less makes [[KleptomaniacHero non-heroic kleptomania]] a sacrament; the Monastery of Madness, which has all the best of bad kung fu, and various minor demon-worshipping cults as well as more benign temples to this or that god or principle. The Church of the Divine Lucre worships money and their prices for services show it.
* DeathIsCheap: Only 375 GP at your local healer. Games 4, 5, and 6 replace it with {{Non Lethal KO}}.
* DeadpanSnarker: The PC's self-narration in 5 can falls into this category.
* DialogueTree: It's a lot like VideoGame/{{Fallout}}'s.
* DugTooDeep: Considered the inevitable result of any mining operation. The usual discovery is a crypt full of undead, but ancient ruins aren't unheard of. (Then again, it's said in the fourth game that all crypts are de-trapped, de-monstered, and looted within months of being occupied, so it's not clear how these ones were missed in the first place.)
* DungeonBypass: Intentionally in the case of the priest spell Move Mountains, which destroys cracked walls. For the unintentional version, see GoodBadBugs below.
* ElementalCrafting: Beginning with stone and working up to steel, then magical. This is pretty well justified in the first two games, where the resources to forge proper steel weapons (rather less magical ones) are scarce and it makes sense for you and a lot of the lower-level mooks to be wielding stone weaponry and "poor" leather armor, and for bronze, iron and steel equipment to be increasingly expensive. Considerably less so once you stop spending the entire game underground and cut off from the surface world.
* ElevatorActionSequence: Twice in the fifth game (with lifts, no less!)
* TheEmpire: Quite literally, because The Empire is its exact name--tough to be an emperor ''of'' something when you rule the entire world. It also has TheEmperor--Hawthorne is either type 1 or 3, Prazac is 4 (albeit technically an Empress.)
* EndOfAnAge: ''Avernum 6''.
* EnemySummoner: in a [[SummonMagic literal sense]].
* EternalEquinox
* EverybodyHatesMathematics: In ''Avernum 2'', you and your party visit a sleepy little bed & breakfast owned by a farmer. While poking around, you discover books owned by the farmer's wife, full of horrifyingly alien texts and eldritch symbols detailing a strange magic none of you can comprehend. If you ask her about it, she tells you what they're about with a sigh: Algebra.
* EverythingFades
* ExactWords: When Erika was first exiled to Avernum, she was cursed so that she would immediately die if she ever returned to the surface. [[spoiler:As her fight with Rentar-Ihrno in ''3'' shows, it turns out "being on the surface" means ''having a single ray of natural sunlight shone on her'']].
* FaceHeelTurn: [[spoiler:Rentar-Ihrno]] in ''3''. [[spoiler:In ''2'', she's one of your main allies in the war against TheEmpire, but the various atrocities committed by the Empire leads her to believe that HumansAreBastards, and she turns into an OmnicidalManiac]].
* FantasticDrug: Skribbane in ''Avernum 3'', ''5'' and ''6''. It gets name-dropped in ''Escape From the Pit'' in the Freehold of Kyass (as the reason for one of Kyass's men going crazy), but you never actually see any in-game.
* FantasticRacism: The Empire hunts down damn near everything that isn't human, and has succeeded in wiping out at least one race of sentient humanoids.
* FantasticSlurs: Nephilim and Slithzerikai are called [[CatFolk kitties]] and [[LizardFolk lizards]] respectively. Avernites are called worms (by people of the Empire) and voles (by those in the Abyss). [[http://encyclopedia.ermarian.net/wiki/Hate_language Here's a list.]]
* FightWoosh: Only for outdoor battles in the original trilogy.
* FireIceLightning: And poison, acid, and "disruption."
* FlowerFromTheMountaintop: In the third installment, there is a quest like this. Said flower is also guarded by hordes of gremlins who [[CharmPerson charm]] you constantly.
* ForcedTutorial: In the fourth and fifth games.
* FriendlyFireproof: Most spells use this. However, Wall of Blades will damage anyone nearby.
* FunctionalMagic: All the "flavors" are used except Wild Magic and MagicMusic. "Styles" are "Mage" (BlackMagic with DarkIsNotEvil employed) and "Priest" (WhiteMagic.) Both Mage and Priest spells include ElementalPowers and SummonMagic, though priests can only summon spirits. Necromancy in the standard sense is mage-only, always evil, and restricted to your enemies.
* GettingCrapPastTheRadar: Look very closely at PhilFoglio's drawings.
* GhostlyChill: A good sign that you're entering a crypt or other haunted place is the sudden chill in the air.
* GlobalCurrency: Explained as barter goods. And in the third game, the currency really ''is'' global, as the Empire controls the entire surface world.
* GodMode: Arcane Shield renders you ''almost'' invulnerable. As it wears off, however, more and more attacks slip through.
* GoodIsNotNice: Erika is the closest thing the series has to a BigGood, but she's haughty, arrogant, and ''violently'' opposed to long term peace between Avernum and the Empire.
* GottaCatchEmAll: The second game has a clear example, the Crystal Souls. The first has you gather and reforge the shards of the sword Demonslayer to fight Grah-Hoth, but [[ReviveKillsZombie a few well-aimed Arrows of Light can also deal with him]]. Some of the games give a soul crystal (not a Crystal Soul) in which you can store copies of monsters to summon later, turning them into {{Mons}}.
* HarderThanHard: Torment. It [[NintendoHard lives up to its name]], particularly in the fifth game.
* HarmfulHealing: In the first three games, never use the "First Aid" action when you haven't trained in the skill. You have a high chance of doing damage to your unfortunate ally.
** Later games use it as an automatic action performed after battles, which restores a small amount of HP and MP, averting the trope.
* HeelFaceTurn: [[spoiler: Rentar-Ihrno in the 4th game, depending on your dialogue choices.]]
** The Nephilim and Slithzerikai undergo this in the second game on, following the player's defeat of the former's more hostile leaders and [[spoiler:cleansing the Slith of Grah-Hoth's taint]] in the latter's case.
* {{Hellfire}}: Quickfire.
* HideYourChildren: Generally they only appear in areas with no monsters. If they're human, anyways--nothing stops you killing a "baby hydra." And often very little stops you from killing a child [[VideoGameCrueltyPunishment if you don't mind the town attacking you on sight]].
* HoistByHisOwnPetard: Emperor Hawthorne [[AddedAlliterativeAppeal cultivated a climate of cutthroat competition]], instituting {{Klingon Promotion}}s and [[LockedAwayInAMonastery underworld exile]] for losers of political clashes in order to keep them from threatening his power. This concentrated a lot of determined resentment among people capable of thriving on being ReassignedToAntarctica, at least one of whom never stopped conspiring revenge, and many others willing to support it.
* HopelessBossFight: [[spoiler:Rentar-Ihrno]] in ''Avernum 3''. [[note]]It is actually possible to win, provided you are very, ''very'' persistent, but according to the small handful of people who have actually done it, the hours it takes to accomplish aren't worth the payout.[[/note]]
* ImAHumanitarian: Well, the bloody bodies in Garzahd's pantry are of indeterminate species, but they look humanoid, and the meat from them is classified as "weird." Creepy meat shows up many times in giants' and ogres' homes as well.
* InexplicablyIdenticalIndividuals: The Merry brothers in the third game.
* InsufferableGenius: The VainSorceress Erika considers over-lengthy titles beneath her. Not everything good in Avernum is her doing, but it's probably fair to say that without her help, the Avernites would not be surviving nearly as well as they have been.
* InsurmountableWaistHeightFence: Plenty of them.
* InvisibleMonsters: Guardians and black shades in the first three games. The only way to attack them is to walk into the seemingly empty spaces they occupy.
* KarmaMeter: The original trilogy has a reputation stat. Completing quests and performing other good deeds raises it. Getting caught stealing and other bad deeds lowers it. A high reputation will make certain [=NPCs=] help you. However, you start off with a low reputation and will almost certainly end up with a high one.
* KickTheDog: Some of Gladwell's quests may be solidly to flimsily justified on a search for knowledge and power ([[{{Munchkin}} which for the player it naturally is]],) but every one of them smacks of ForTheEvulz motivation on his part. Combines with YouBastard, as the player receives passive-aggressive guilt trips from characters who couldn't possibly know their involvement.
* KindheartedCatLover: Motrax the Dragon. Unlike his siblings, he's not reclusive, power-mad, or spiteful towards humans, preferring to actually trade knowledge with visitors. He also considers cats "remarkable".
* KleptomaniacHero: You. But {{NPC}}s only care about some items. What's more, you never need worry about which ones, because the game ''tells you outright''. Imagine walking into a store with candy bars labeled "Don't steal this one, it's Not Yours" and the sure knowledge that no one will mind if you hork all the rest of them.
* KnightsAndKnaves: Referenced but averted by a sign in Erika's tower in ''Escape From the Pit'':
-->One goblin tells the truth,\\
The other lies.\\
[[CuttingTheKnot Pierce them both to get the prize]].
* LaResistance: The Scimitar.
* LastChanceHitPoint: Standard mechanic in the first three games. This is exploitable if you pick a fight with an enemy that's significantly above your level, but can only attack once per turn.
* LemonyNarrator: Particularly in regard to being a DeadpanSnarker.
* LightAndMirrorsPuzzle: Several in the Golem Factory in ''Avernum 3''. The goal is generally to point the lasers in such a direction that they won't block your path. (Which is odd, because you [[InsurmountableWaistHighFence ought to be able to crawl under them...]])
* LimitedSoundEffects
* LinearWarriorsQuadraticWizards: Priests and mages tend to become demigods in the second half in the games, vastly overshadowing the warriors' usefulness. Averted, however, in ''Avernum 6'', with the introduction of dual-wielding. A properly built fighter is the best source of single-target damage in the game.
* LockedDoor: Typically, any door you aren't supposed to get through has an absurd value required to pick/bash it, like 200, where a good thief has a skill of maybe 15. However, in the earlier games, having the Unlock Doors spell learned at the highest level possible meant you could unlock those as well.
** In ''Escape From the Pit'', the game outright tells you when a door isn't meant to be picked.
* LuckStat
* LuckilyMyShieldWillProtectMe: To balance out the greater attack power of spears in the later games, they're all made two-handed, swords are all made one-handed, and shields become very effective at reducing damage.
* MageTower: The [[CaptainObvious Tower of Magi]]. Erika, Patrick, and Solberg also have their own towers in the first two games (Erika has a new one in game 3).
* MagicAntidote: Apparently literal.
* TheManBehindTheMan: [[spoiler:When you assaassinate the Slith King Sss-thsss in the first game, King Micah then dispatches you to look into the destruction of Fort Remote. Grah-Hoth reveals himself, and expresses anger that you killed his "pet".]]
* MinmaxersDelight: Divinely Touched.
* MildlyMilitary: For some reason Avernum's military is fond of sending its ill-prepared new grunts (not even special forces or shock troops) out on scouting missions in groups of four (in plainclothes, no less, though somehow other Avernites will recognize you as a team of soldiers), while the better-trained and stronger troops remain to guard the fort. In most of the cases the loose justification is that you're actually PrivateMilitaryContractors (and therefore disposable).
* MirrorMatch: In the fourth game, you'll encounter a few instances where you'll have to fight a party that mimics the game's cookie cutter party layout: Human warrior, Nephil Archer/Slith rogue, Human Priest, Human mage.
* MissingSecret: Missing minor secrets are favored by Spiderweb.
* MoneyForNothing: Things worth buying are rare by the end of the game in the original trilogy. You either max out on gold or spend it on frivolous things. By the third game, however, spending money on training can keep your cash valuable all the way through.
* MoneySpider: Averted. Enemies usually have relevant loot, and frequently make use of any consumables they get spawned with. Some enemies do drop money, but only those that would believably carry some.
* MookMaker: The essence of the plot of the third game. There are also some monsters that behave this way.
* MultipleEndings: ''Escape From the Pit'' has [[spoiler:a Safety ending where you save Avernum from the demon Grah-Hoth and transform it into a secure nation, a Freedom ending where you lead the people of Avernum back to the surface, and a Revenge ending where you topple TheEmpire.]] Interestingly, [[spoiler:its possible to complete ''[[GoldenEnding all three at once]]''.]]
** This needs a bit of clarification. [[spoiler: First, only escaping Avernum actually ends the game. The other two let you continue playing, and if you choose not to leave once you find the exit, you can keep playing. Second, killing the Emperor does not topple the empire at all. In fact, the empire invades Avernum in the next game as revenge for the assassination. Third, while killing Grah-Hoth does make Avernum a safer place, it is still quite dangerous, just no longer at risk of imminent demonic invasion. It is hardly a "secure nation."]]
* MySpeciesDothProtestTooMuch: The Sliths and Nephils are your foes in the first game and [[MonsterAllies playable species]] in the second -- the Sliths even state a distinction between "Darklings" and those who don't kill everything that moves. Also, Motrax the friendly [[OurDragonsAreDifferent dragon]] (and Melanchion in 5 and 6) and a few non-hostile ogres.
* MysteryMeat: "Weird meat" comes from a variety of sources, of which the ''least'' disturbing is giant lizards used as livestock. At least one example ([[BigBad Garzahd's]] "pantry") is apparently humanoid in origin, maybe even [[ImAHumanitarian human]]. However, all of it can be eaten without harm.
* NarrativeProfanityFilter: "Those blinking, farging porgers don't have the blanks..."
* NoCanonForTheWicked:
** Inverted in the second trilogy, as [[spoiler:even if you kill [[EvilSorcerer Gladwell]] in the current game, he still shows up alive in the next game]].
** Played straight in ''5'': You can choose to ally with either [[spoiler:the Empire or the Darkside Loyalists, and your allegiance determines whether General Redmark or Dorikas becomes Emperor. ''VI'' reveals that the Emperor is Redmark, and that the Darkside Loyalists were (mostly) eliminated]].
* NotMeThisTime: In ''Avernum 3'', your party is trying to figure out who created the plagues of monsters that are attacking TheEmpire. You can question the dragons, the Vahnatai, and the sorceress Erika, all of whom have grudges against the Empire and the means to create the monsters, but they all insist that while they hate the Empire with a passion, they have nothing to do with this. It's up to your party to figure out which--if any--of these are responsible.
* NotSoHarmlessVillain: In ''Escape from the Pit'', the bandit Legram serves little purpose other than to serve as your intro to combat at the start of the game. [[spoiler:Late in the game, he reappears not only ''much'' stronger than before (complete with an upgraded sprite), but he has an entire team of high level bandits and monsters at his command.]]
* NPCAmnesia
* NumericalHard
* OhCrap: In ''Escape from the Pit'', Legram's thugs have this reaction if you choose to immediately attack rather than plead for mercy as they expected.
** In 4, you're marching up to the front gate of the [[VeryDefinitelyFinalDungeon Very Definitely Final Dungeon]], when suddenly the nearby defense pylons turn on. Note that the same pylons are implied to have massacred a force of ''thousands'' of Avernite soldiers earlier in the game.
* OneSizeFitsAll
* OpeningTheSandbox: The final chapter in ''Avernum 2''.
* OrganDrops: Fortunately, they're usually quest items rather than food.
* OurMonstersAreDifferent: In quite a lot of ways.
** BlobMonster: Slimes. Not very tough, but their attacks are acidic, and one variety [[AsteroidsMonster splits in two every time it's damaged]].
** {{Demons}}: Of a secular variety, believe it or not. They're a ProudWarriorRace with a sadistic sense of humor, but they spend most of their time fighting each other.
** GiantSpider: A variety, including the Giant Intelligent Friendly Talking Spiders (and Roaches, in the third game). There are even evil magical spiders, called aranea.
** {{Golem}}: Often found protecting powerful wizards.
** TheGreys: Vahnatai look the part, and generally fit the role as an ancient, mysterious species with uncertain motivations regarding humanity. This being HeroicFantasy, they rely on {{Power Crystal}}s rather than technology proper, but they do seem to be telepathic. They're also pretty high up the SortingAlgorithmOfWeaponEffectiveness--even a basic "waveblade" (flamberge) significantly outdamages an iron sword, and their "razordisks" (FuumaShuriken) are pretty much the sole reason Throwing Weapons is a viable skill.
** {{Hellhound}}: Added in the fourth game, and resemble the roamers from ''VideoGame/{{Geneforge}}'' (which is from the same developer and uses the same engine). They don't seem to be genuinely demonic, but they do breathe fire at you.
** LizardFolk: The Slithzerikai.
*** ReptilesAreAbhorrent: Subverted; in the first game, they're introduced as an enemy, but they're only fighting you because of the warlike leader Sss-Thsss commanding them. [[spoiler:Then you find out that he and many of the others were influenced by demons, so now you have to rid the sliths of their taint.]] By the second game, most sliths are peaceful, though you still have to deal with some slith brigands from time to time.
** ManEatingPlant: Well, technically man-eating fungus.
** OurDragonsAreDifferent: Avaricious, arrogant, and annoying, they're also ridiculously tough. Fortunately, only five of them are left alive as of the first game. Unfortunately, they're breeding...
** OurGhostsAreDifferent: Some ghosts are friendly. Shades, Black Shades, Greater Shades, Spirits, and what have you? Not so much, unless you summoned it. Usually.
** OurGiantsAreBigger: They're a ProudWarriorRace ''and'' they [[ReligionOfEvil worship pain]].
** OurGoblinsAreDifferent: They start out seeming AlwaysChaoticEvil, but turn out to be {{Barbarian Tribe}}s that only commit banditry because it's "what goblins do best."
** OurZombiesAreDifferent: Well, there are zombies, ghouls, ghasts, quickghasts, and the odd specter. Vahnatai even have vahnavoi for physical and hraithes for magic.
** RodentsOfUnusualSize

** TheUndead: As of this writing, the games have used every entry on the page ''except'' FrankensteinsMonster, {{Mummy}}, and TheGrimReaper.
** {{Unicorn}}: There are a few friendly ones, but most of the ones you meet try to kill you. Across the board, they're all considered ugly unpleasant pests rather than majestic creatures.
* OutrunTheFireball:
** Several cases of outrunning quickfire in the original trilogy, including across the roof of an enemy fortress in the second game.
** The Test of Speed in the second game drops you in a room, and when you touch the door, the opposite wall opens up, releasing quickfire. You have to make it through a maze to the door before dying. Since the quickfire moves three steps to your one, it seems hopeless... until you realize that, compared to the world around you, you actually move ''faster'' while in combat mode (four or five steps per turn). Now if it weren't for those damned goblins...
** Outrunning an [[spoiler:exploding Empire portal]], in one case. Jeff Vogel must like this trope.
* PamphletShelf
* PlanetOfSteves: The Giant Intelligent Friendly Talking Spiders are all named Spider.
* PortalNetwork: In the second trilogy.
* PsychoSerum: Skribbane. See FantasticDrug above.
* PurelyAestheticGender: It's not registered in the game system anywhere; you can choose a male- or female-looking character portrait (and in case of non-human races it's not really clear which are which) and that's about it.
* RashomonStyle: Different {{NPC}}s who have been in Avernum since early on in its history tell you different stories about those early years. Notably, Erika claims to have invented the light-giving fungus on the cave walls, whereas actually it was just there when they arrived.
* ReallySevenHundredYearsOld: The Vahnatai.
* ReligionOfEvil: Tons and tons of them.
* RevengeBeforeReason: Erika is ''obsessed'' with toppling the Empire, and doesn't give a damn if innocent lives are lost in the process.
* RewardingVandalism: Breaking into people's houses, even if you don't take anything, can earn you XP, as long as you're careful and don't get caught. Some valuable items you can even take in plain sight, as long as they're not marked "Not Yours".
* {{Shareware}}: The earlier games make a joke out of having your path blocked by the "Shareware Demon", who demands that you perform the "Rite of Registration". You can play a very substantial portion unrestricted before that point, though.
* ShoutOut:
** To WesternAnimation/SouthPark in one of the Blades of Avernum scenarios. There is a statue guard with a muffled voice [[spoiler: who gets smashed by an explosion.]]
** In the third game, there's a Burma Shave ad.
--> Before they send us
--> to a grave
--> Alien Beasts use

* SmallNameBigEgo: Legram of ''Escape From the Pit'' is this, thinking he's to become the great leader of a bandits' paradise. To the point where [[spoiler:his last words are that he knows your weakness, and that he will defeat you next time... cue him falling dead]].
* {{Sssssnaketalk}}: The Slithzerikai, a race of lizardmen native to Avernum, speak like this. Some learn English well enough to avoid it, though.
* SoloCharacterRun: Many players opt to use just one character (a "singleton"). The only two major problems are skill selection and loot hauling.
* SpaceCompression: Averted in the earlier games, where there were two scales--Outdoor Mode and Town/Combat Mode, which made the world actually seem gigantic. After the engine change, it just seems like the cities are placed next door to each other.
* StarterVillain: Legram in ''Escape from the Pit''.
* StockScream: In some games in the series the Wilhelm scream can be heard upon dying.
* SufficientlyAnalyzedMagic: Wizards are basically scientists (often [[MadScientist mad ones]]) and the Tower of the Magi is basically a research university. Some wizards will ask for your help with experiments, to test whether some spell or creation is safe (no).
* SuperDrowningSkills: Normally the game doesn't allow you to enter water, but when it does happen, it's an instant death.
* TakeYourTime: Most of the games, though in the third towns will be destroyed if you wait too long. And don't expect much Tower of Magi usage after [[spoiler:day 160]] comes around, though [[spoiler:at least you'll still be able to get training from 'X' and Solberg]].
* TalkingAnimal: Giant Intelligent Friendly Talking Spiders. As ''Blades of Avernum'' puts it, "Some creatures are more dangerous, but few are [[AlienScrappy more irritating]]."
* TalkingTheMonsterToDeath: Once or twice a game. The fourth had a particularly unusual approach--every enemy who talks to you before fighting you gives you a dialogue option that seems like it would lead to this, but in all but one case you fight no matter what option is chosen. That one case is unmarked, apparently a bonus for roleplayers.
* TechnologyMarchesOn: All of the games will run in any incarnation on [[IBMPersonalComputer Windows]] [=OSes=] (all the way back to the ''Exile'' games) with maybe only a few minor compatibility tweaks at best on 32 and 64 bit [=OSes=]. {{Macintosh}} (for which the games were originally made) has problems running the older games on their newer OS versions, hence the {{Updated Rerelease}}s.
* {{Tuckerization}}: See [[http://www.spiderwebforums.com/forum/ubbthreads.php?ubb=showflat&Number=122074#Post122074 this thread]] for a list.
* UltimateBlacksmith: There's only one fellow in the original game who can reforge Demonslayer. Played with in that he lives in a major town and isn't hard to find--but he doesn't live in the metalworking "capital" of Avernum (Dharmon); instead, he's [[spoiler:in the mining town of Fort Draco]]. The third game has only one smith who can forge swords out of mithril, and he lives in an otherwise inconsequential town in a boring corner of a frontier province. He is of very questionable sanity, at best.
* UniversalPoison
* VainSorceress: Erika considers any magician who tries to look important via lengthy, impressive titles a blowhard -- probably because being the acknowledged best, titles are ''beneath'' her. She certainly demonstrates the arrogance and haughtiness of the trope, especially when venting her bitterness toward old topside rivals. Rather proud of her beauty, too.
* VendorTrash
* VideoGameRemake: Of the ''VideoGame/{{Exile}}'' series.
* VideoGameCrueltyPotential: With a few plot-based exceptions, you can kill off every inhabitant of most towns and still win the game. The exceptions generally get you an automatic NonStandardGameOver when you try.
** In ''Avernum 1'', you can smash the eggs of a hostile Slith tribe, if you don't mind fighting the angry lizardmen who attack in response. In ''Avernum 2'', you can kill the hatched children of another hostile Slith tribe and leave their tiny bodies floating around in a pool of water, with the same result of the tribe attacking you. Good thing the game only describes what is done to their young.
* VillainEpisode: In the fifth game you play as Empire soldiers sent to Avernum on a mission.
* WeBuyAnything
* WithThisHerring: Always present, always [[JustifiedTrope justified]]--for instance, in the fifth a double agent stole all the equipment you were supposed to get.
* YouAllLookFamiliar: Lampshaded three times in the third game.
* YouAllMeetInACell: The first game starts off with the party getting thrown into Avernum.
