One thousand years ago, [[{{Gotterdammerung}} the gods and the most powerful demons enacted an extremely destructive war called Ragnarok]]. The gods, who otherwise would have lost, broke the taboo that mortal creatures must not have godly powers in order to create the Grim Angels, incomplete yet extremely powerful beings who were able to turn the tide. Afterward, the gods vanished, sealing their powers within the recently liberated land of [[VideoGame/RivieraThePromisedLand Riviera]] and entrusting the rule of Asgard to seven proxies called the Magi. The Grim Angels, too, were sealed away until the time would come that their powers would once again be necessary to protect Asgard from the threat of demons.

Since that time, TheVerse has been locked in something of a status quo: Demon factions are always on the lookout for a chance to attack Asgard or otherwise expand their turf, and the [[HaveYouSeenMyGod now-godless]] Asgard must continually discourage them. Thus, there is a constant battle of OrderVersusChaos being waged on a cosmic scale. Not helping things is that the Magi, originally humanoid beings with all-too-mortal desires, are waging a constant and quiet political war amongst themselves.

And so, in the countless mortal worlds that lie between Asgard and Niflheim, life tends to be rather grim. And to make matters worse, even when their lives ''aren't'' being sidelined by the heavenly cold war, [[HumansAreTheRealMonsters the people of the human realms have usually got their hands full persecuting and killing each other]].

This is the setting of Creator/StingEntertainment's Dept. Heaven series. Each game released thus far has taken place in a different mortal world, depicting the struggles taking place therein (and, often as not, how interference courtesy of Asgard and demons has made it worse). The series as a whole is known for its GenreBusting gameplay, [[DarkFantasy dark storylines]], [[GrayAndGreyMorality morally ambiguous characters]], purposeful ArtStyleDissonance,[[note]]Creator/SatokoKiyuduki, famed for her [[PuniPlush puni-moe\]] art style, has been the art director since the second game, 'natch[[/note]] and oblique references to Myth/NorseMythology.

The series is meant to span [[NumerologicalMotif nine core episodes]], not counting spinoffs. It should be kept in mind that episode number has nothing at all to do with series chronology,[[note]]The episode numbers are in fact just the order that the games' original concepts were pitched in[[/note]] and that the games are released out of chronological order as well. Usually, though, series mainstay characters (most often the archangel Marietta) will pop up briefly to give series fans an idea of when the story takes place.

Those of the games which have made it into English have always been localized by Atlus,[[note]]and TLC'ed by 505 Games for Europe and Australia[[/note]] and around the time of the announcement of their localization of ''Knights in the Nightmare'', it was announced that Atlus of Japan would be Sting's exclusive publisher. Ideally, this would ensure that this series would continue being localized for the foreseeable future. ''Ideally.''

** ''VideoGame/YggdraUnison'', an [[GaidenGame alternate-universe spinoff]] that gives [[DemotedToExtra almost]] everyone a chance to be the main character. Originally released as a cellphone-exclusive [=MMO=] in 2007, but a DS remake was also released in late 2009. NoExportForYou.
** ''VideoGame/BlazeUnion: Story to Reach the Future'', a PSP-only prequel to ''VideoGame/YggdraUnion''. The game takes place in Bronquia three years prior to ''Yggdra'''s story, and focuses on Gulcasa ([[spoiler:Garlot]]) and the Imperial Army. Released in 2010. NoExportForYou.
** ''VideoGame/GloriaUnion: Twin Fates in the Blue Ocean'', another PSP game. Is largely unconnected to the other Episode II games, and is a {{pirate}} dramedy. Released in June 2011. Still NoExportForYou.
* '''Episode III:''' Currently planned as an MMO of some type, although production is on hiatus. Ito mentioned that it is supposed to take place roughly at the same time as ''Knights''. See [[ this interview]] for details.

!!Common tropes utilized in this series:
* AerithAndBob: The range of names goes from "normal" (Rose, Marietta, Luciana) to "a little strange, but believable" (Malice, Nordische, Kylier) to "downright bizarre" (Staehelingum, Medoute).
* AllThereInTheManual: Good luck piecing together the full plot without the World Guidance books and the various interviews with the director.
* BittersweetEnding: As stated in an official interview, "Sting games don't have happy endings", so even the better outcomes to each game come with uncertain futures, fallen comrades, or both.
* BlueAndOrangeMorality: The gods.
* CelestialBureaucracy: Which is currently being taken care of by a...
** CouncilOfAngels
* DarkerAndEdgier: ''Knights'', ''Blaze Union'', and ''Gungnir''.
** LighterAndSofter: ''Unison'', ''Riviera'', and ''Gloria''.
* DemonLordsAndArchdevils
* FallenAngel: There's at least one in each game. Most of them are at least somewhat sympathetic.
* FantasticRacism: In many flavors.
* FromBadToWorse: Marietta's character arc through the series.
* GenreBusting: Gameplay-wise, [[DoingItForTheArt this is the whole point of the series]].
* GoodIsNotNice: Oh boy. Asgard is acknowledged everywhere as the force preserving order, but it is filled with [[FantasticRacism racist, elitist fanatics]] and is [[spoiler:run by the BigBad]]. It was no better when the gods were in charge, even--they had a nasty habit of raining down DisproportionateRetribution upon anyone that looked at them funny.
** LightIsNotGood / DarkIsNotEvil: In all games but ''Riviera''.
* GrayAndGreyMorality: All games except ''Riviera''.
* GreaterScopeVillain: [[spoiler:Hector]] until ''Riviera.''
* HaveYouSeenMyGod
* HostileShowTakeover: The Episode II games have become as much Gulcasa's story as Yggdra's (they each have main-charactership of two); Yggdra has usurped partial main-charactership of ''VideoGame/KnightsInTheNightmare'', and has been featured in the concept art for Episode IX.
* LazyBackup
* MindScrew
* MultipleEndings: And in every game that sorts its endings by letter, the A ending is always canon.
* OrderVersusChaos
* OurAngelsAreDifferent
* RageAgainstTheHeavens: What a number of the antagonists are trying to do. Perhaps not surprising, given Asgard's preferred management methods.
* SlidingScaleOfIdealismVersusCynicism: After Riviera? Firmly cynical.
* SortingAlgorithmOfMortality: Aside from [[PlotArmor the]] [[WeCannotGoOnWithoutYou hero]], no one is truly safe. Love interests may be able to [[DisneyDeath escape on a technicality]], but especially in the episode II games, no role is more dangerous than that of [[UnluckyChildhoodFriend the hero/sidekick's childhood friend]].
* WhoWantsToLiveForever
* YouCantFightFate: Every game but ''Riviera,'' which actively promotes ScrewDestiny.
