** The TabletopGame/{{Ravenloft}} novel ''Lord of the Necropolis'' has been sealed in the earth below canonicity with an Imprison spell for revealing the nature of the Dark Powers, which is a thing you are really, really not allowed to do.

*** The setting was officially ended with the module ''Faction War'', which ended with the Lady of Pain putting out a declaration that all factions were required to leave Sigil. Faction members could only stay if their renounced their faction. Half the factions were already dead by that point and many of the rest disbanded. In every 3rd, 4th, and 5th Edition book featuring references to Sigil, all 14 factions are still alive, well, and in Sigil. (''Magazine/{{Dragon}} Magazine'''s 3.5 edition ''Planescape'' material was an exception, referring to the factions regrouping elsewhere on the planes and former factioners in Sigil who still believed the same stuff but weren't organised about it.)

** In the novels, Dunkelzahn's death was a [[spoiler:HeroicSacrifice meant to help his agents prevent a premature invasion of Earth by the Horrors because of a side effect of the Great Ghost Dance]]. But in all subsequent sourcebooks, this aspect of the event is rarely touched upon, with Dunkelzahn's death being an assassination by unknown parties. One of the exceptions was in ''Harlequin's Back'', [[spoiler:where the players have to fix the aforementioned side effect]], and the prologue implies that Dukelzahn is, on some level, the one setting it into motion. This ''still'' fits in the continuity of the game, technically, as only maybe ''two'' people know what really happened to Dunkelzahn (Harlequin is one of them, and even he's not entirely sure). As far as everyone else in the world is concerned, it really ''was'' an assassination by unknown parties.

** ''War of the Spark-Forsaken'', a ''Magic'' novel published in 2019, has largely been ignored by subsequent authors contributing to the ''Magic'' canon, not in the least because of the HideYourLesbians issue with the character of Chandra Nalaar being retconned from being pansexual to always having been heterosexual and [[ShipSinking sinking a very popular ship]] in the process.

* ''TabletopGame/MagicTheGathering''. Karona meeting [[BigBad Yawgmoth]], apparently still alive, in the ''[[Literature/OnslaughtCycle Scourge]]'' novel has been {{retcon}}ned as having been an impostor. Or it could have been a {{Psychic Dream|sForEveryone}} of the past.

** While the ''TabletopGame/ForgottenRealms'' is usually content to pull a {{Retcon}} or push the Reset button, occasionally they'll outright declare something this. Prior to 5E, there was a rule that if anyone tried to imitate a wizard by using their personal magic seal, they would be punished by the divine intervention of Mystra, goddess of magic. 5E flatly calls this a ridiculous story that was never true and was probably made up by the wizards themselves to discourage the practice.

* This mixed with OurLawyersAdvisedThisTrope has brought about the final resolution to the Unseen debacle that has plagued ''TabletopGame/{{Battletech}}'' since at least 1995. In June, 2015, Catalyst Game Labs began phasing in new designs for the iconic Unseen designs that cannot be legally used or shown [[note]] Technically, the ''artwork'' for the 'mechs not derived from ''Anime/SuperDimensionFortressMacross'' (which is totally off-limits) can be used, but everyone involved doesn't want another headache with art that wasn't made in-house by FASA/Fanpro/Catalyst[[/note]], ones that are evocative of the originals but different enough to be considered legally original works. Catalyst has officially stated that the original "Unseen" art is no longer canonical.

** Because no one's entirely sure if the Chaos God Malal is owned by Games Workshop or the comic book author who introduced him to the franchise, GW dropped all mention of him from their gamebooks to be on the safe side. He still gets a few references; for example there's a Chaos Space Marine warband called "Sons of Malice" that wears Malal's colors, the rulebook for the spinoff game ''TabletopGame/{{Inquisitor}}'' includes a weapon very similar to the ones used by champions of Malal in the list of daemon weapons, and he appears in one of the short story collections GW released, though he is know as "Malice" there.

** The ''Storm of Chaos'' campaign for 6th edition, after a number of things with the story progression didn't go as planned (Its lore was supposed to follow player input depending on battle results, but [[BigBad Archaon's]] Chaos hordes [[EpicFail got trounced so badly]] in what was supposed to be [[ADayInTheLimelight their spotlight]] that [[Creator/GamesWorkshop Geedubs]] ignored the results to push their own story, [[BrokenBase angering the fanbase]]), was declared null and void and all references to it removed from the ''Warhammer'' canon (a AlternateUniverse set after its conclusion is the setting for ''TabletopGame/WarhammerFantasyRoleplay'''s second edition). Some of the events of ''Storm of Chaos'' were given {{Shout Out}}s in later official storylines and ''TabletopGame/WarhammerTheEndTimes'' is considered its SpiritualSuccessor.

** Due to the KillEmAll nature of the transition between ''Warhammer Fantasy'' and ''Age of Sigmar'', several characters who were killed off in the former were eventually brought back in the latter. For example, the aforementioned Eltharion came back as a suit of AnimatedArmor, whereas Sigvald the Magnificent was resurrected as a Daemon Prince.

* ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'':

** The [[OurDwarvesAreAllTheSame Squats]] were space dwarfs that got stricken from the records, partly due to a shift towards a [[ShooOutTheClowns "more serious"]] direction, partly because their attempted army book became an absolute mess after pre-production. For a while it was established that they ''did'' exist, but had been entirely eaten by [[HordeOfAlienLocusts Tyranids]]. They now exist again as a type of [[HumanSubspecies abhuman]]. They don't have any models though, and are basically just relegated to a minor bit of background fluff.

** The Fimir, Games Workshop's first try at an original creation (rather than re-branded miniatures designed for other properties) got almost entirely excised from canon. Mechanically, a mix-up had given them medium creatures stats while they were built and priced as large creatures. Lore-wise, they were an all-male race that could only reproduce through... well, {{rape|AsDrama}}. In a brand that was going for teenage audiences. They've slowly been reintroduced through Forge World and references in the 8th edition Rulebook, but are substantially different.

* The third edition of ''TabletopGame/{{Cyberpunk}}'', called ''V3'' or ''Cyberpunk 203X,'' leaned away from the series' traditional grit and genre tropes in favor of PostCyberPunk, ScienceFantasy, and themes of transhumanism. In addition, Creator/RTalsorianGames couldn't afford to commission artwork to illustrate the corebook, instead using monochrome photos of action figures posed by the founder's wife overlaid with a hideous green tint (which led to the derisive FanNickname "Barbiepunk"). In 2020, a newer edition, ''Cyberpunk Red,'' was released to coincide with the launch of ''VideoGame/Cyberpunk2077'', and included {{RetCon}}s to several key plot points of ''203X''.[[labelnote:Namely...]]Instead of destroying the planet in an atomic holocaust, the Fourth Corporate War ended with the Arasaka Corporation being effectively banished to Japan after nuking the heart of Night City. The [=DataKrash=] virus didn't permanently disable all NET functionality, but limited connectivity to city-specific local datanets and turned the rest of cyberspace into a wild frontier filled with rabid A.I. The "carbon plague" which erased all paper and led to most history being forgotten or [[AllHailTheGreatGodMickey misremembered]] is described as raging briefly, then stopping suddenly. Everyone still remembers what year it is.[[/labelnote]]

For a while it was established canonicity that they ''did'' exist, but only just long enough to be entirely eaten by [[HordeOfAlienLocusts Tyranids]]. Then the Squats came back, but recognized as a type of abhuman rather than a distinct race.
