"Why does the third of the three brothers, who shares his food with the old woman in the woods, go on to become king of the country? Why does James Bond manage to disarm the nuclear bomb a few seconds before it goes off rather than, as it were, a few seconds afterwards? Because a universe where that did not happen would be a dark and hostile place. Let there be goblin hordes, let there be terrible environmental threats, let there be giant mutated slugs if you really must, but let there also be hope. It may be a grim, thin hope, an Arthurian sword at sunset, but let us know that we do not live in vain."
- – Sir Terry Pratchett, “Let There Be Dragons” (A Slip of the Keyboard)
NobleBright is an adjective derived from the term often used to describe Warhammer 40k: Grimdark. Just as every hero has a "mirror opposite" version that is evil, it's supposed that there must be a mirror opposite version of the heroes of WH40k where everything goes RIGHT. It can also be used to describe artwork that has a noble/bright feel, even if the setting itself would not normally be considered noble or bright.
Where the GrimDark tag usually describes a setting in a slow, painful decline, the NobleBright tag usually describes a setting emerging from a dark age and either returning to or in the midst of a golden age.
Example: WarHammer vs. BrightHammer
"We do not need a Warmaster in this age. A Warmaster would fail us. We need a DADDY." - Custodes showing their appreciation to Captain-General Kitten
This alternate universe setting, BrightHammer40k, comes with the tagline "In the Noble Brightness of the far future, there is only HIGH ADVENTURE!" This is as opposed to the original tagline of Warhammer 40k, which stated, "In the grim darkness of the far future, there is only war." BrightHammer40k's setting has strong 1920s-1940s pulp fiction themes, crossed with an "age of myth" bronze age culture.
Differences between WarHammer 40k and BrightHammer 40k include:
- The setting is loosely divided into city-states united by race, religion, philosophy or just simple common sense, rather than singular empires defined by paranoia.
- There is a wide variety in the type of characters, nations, flora and fauna, and major characters in the setting.
- Speaking of wide varieties of characters/nations, relations between different groups, whether cultural, political, racial, etc. are usually positive. Conflicts are either out of just cause or have the option of being resolved peacefully. (Unlike Grimdark, in which "conflict resolution" is usually genocide)
- There is an overall "pulp fiction" feel. Just like real life.
- The universe is old, in the process of rediscovering a forgotten golden age.
- Low level conflicts such as raiding are considered common, but war is not. Just like Mongolia.
- When a Noblebright universe has a war, it's usually for a well defined, just cause. Wars are usually fought with "smart" technology, and massive, endless slaughters are rare. (Grimdark usually devolves technology in some form, then throws in massive slaughters for the fun of it)
- Technology is wildly inconsistent. Just like Alaska.
- Villains are over the top, campy, and rarely played seriously. Very much like North Korea.
- Leaders are usually diplomats or wise "philosopher-kings" like in North Korea.
- Heroes do most of the heavy lifting in society, and there are heroes, great and minor, at every level of society.
- There is a strong emphasis on individual strength. (Grimdark focuses on the massed collective. Individual strength is insignificant in the enormous Grimdarkian Machine)
- Good guys can be jerks, but are still good guys.
- Over-the-top heroism usually carries the day.
- Obvious, thinly disguised Secret Agents everywhere.
- The setting is entering a technological renaissance.
- Everything is bright or vividly colored.
- As seen on TV!
Compared to Warhammer40k, Brighthammer40k is generally brighter and a nicer place to live, but is by no means peaceful, always in a low level state of conflict, internal and external, never quite turning into war. The skull motif is replaced by wings, and colors are often brighter.
Strikes a balance between Noblebright and Grimdark. Basically, you don't matter much, but if mankind can put their back into it hard enough, it'll turn out okay in the end:
- Big E is alive, and regenerating.
- Primarchs still exist
- There is hope for a better future. Even if you don't live to see it, your children may well.
- While the AdMech got buttfucked twice, it's slowly getting it back together.
TL;DR of the Spectrum
- Grim/Noble = whether the future prospects of the setting looks positive/negative, and whether anybody can accomplish anything significant for good or evil. Hope vs. despair.
- Bright/Dark = determines the current state of things. Is it generally a good place to live or a bad one?
8chan Explanation of the Grim/Noble and Dark/Bright Spectrum (by anons)
Grim/Noble asks whether there are heroes that exist, may appear to change the world for good or ill.
- A noble setting isn't one where everyone is good, more like one where people are active. The actions of a single hero can change the world, and a single big villain can ruin it: there are important people, who are so either by birth, rank or sheer willpower, and every single one of these people MATTER.
- In a grim world, no matter what you do, an individual can't secure more than an individual victory, if even that, because the rest of the world is too big/scared/powerless/selfish to act upon his impulse.
Something like Morrowind or Berserk is noble (bright and dark, respectively) because it is about one man forcing destiny's hand and changing the world.
- Now, a bright world is one full of opportunity, of wondrous sights to behold. It doesn't mean that it has to be MLP, it can be dangerous, but your first instinct when looking at a new location should be awe and wonder: people may adventure to save the world, but they leave town with a smile upon their face, eager to see what comes next. The shadow of Risk is largely erased by the glint of Adventure. In a bright world, it's quite possible for people to go on adventure just for the hell of it, since the journey is its own reward. Resurrection, or at least means to heal grave injuries, is usually accessible, to counterbalance the fact that the risks out there are real.
- A dark world is one where life sucks, and something or someone is poised to kill everybody else in the story - whether it be demon overlords, 'nids, or even the lack of water, if this threat has its way everyone dies and they die for good. If you lose an arm, you play a cripple. In the extreme cases, even when you win a fight, your career is over (i.e. gangrene). This means that, even though people may be ready to help (noble), they'll need a damn good reason to do so, since stepping out of line is so dangerous (dark).
Given is an example of each type of setting to show how the combinations of noble/grim and bright/dark work;
- 40k is (grim)dark because, no matter where you go, there is only war, and heroism's only reward is usually a notch on a gun or a corpse in a trench. No matter who you are, most of the galaxy probably wants you dead, and staying home today is the best choice you can make. Even if you make it to the end, you may have to sacrifice everything to save everyone, if you haven't already done so.
- Berserk is (noble)dark because, while there seems to be light at the end of the tunnel, it takes men and women of insane willpower to get there: no matter whether you are big or small, even when you have nothing, the only thing that may save the world is the will within you screaming, "Go on!" And if hope was to fail, you're getting a book-long bloodbath-orgy, and all its consequences.
- Morrowind is (noble)bright because, even though the world is fraught with dangers, you can fix everything. The reason it isn't dark is because there is so much to see, so many interesting people to meet, so many cool things to experience that, at the end of the road, you'd do it all over again if given the chance to see it once again with virgin eyes.
- Sandman is (grim)bright because the incredible vistas and interesting people are all that can distract Dream from the dullness of his existence. He will tire of them all, but even he has to admit that he saw some cool shit. Also, notice how the relative freedom from consequences (people can get somewhat rezzed/healed/characters don't die much), a bright trait, reinforces the futility of the struggle in a grim world.
In short, grimdark and noblebright worlds both exist, and both are interesting to play in. So do grimbright (perhaps these are the most narratively counterintuitive and hardest to pull off, but simultaneously they can be the most interesting worlds to run in) and nobledark (seems to be enjoying a big surge in popularity these days - people like the aesthetics and adult nature of dark worlds, but not the crushing nihilism; in nobledark, most things suck, those rare moments of genuine nobility and decent change are all the more poignant, even if they come at great cost). Every type allows for evil and struggles to exist, and for stories to be told. Noblebright is not (usually) utopian or down to shiny, pleasant aesthetics (after all Adventure Time looks textbook Noblebright but is actually sugarcoated Grimdark) and evil can even triumph: it's less of a matter of who wins, and more of a matter of tone. In a bright world, the BBEG can win, but he won't skullfuck to death everyone the PCs know in front of a crowd without the mood turning to dark.
Some examples of each:
- Warhammer, both kinds - Warhammer 40000 coined the term Grimdark from its tagline, so goes without saying.
- A Song of Ice and Fire / Game of Thrones
- Star Wars, if you leave out the "good vs. evil space fantasy" factor and consider that millions, if not billions die simply because of the will of some omnipresent force, in this case, the Force.
- E.Y.E Divine Cybermancy
- Gears of War - Basically a world in which humanity has been at war with itself and genocidal mutants for over a century. The world is apocalyptic and everyone uses chainsaw bayonets to saw their enemies in half.
- Killzone 2-3 - If Space World War Two met Gears of War, Killzone is the product: A genocidal war between humanity and a mutated version of them on a wasteland planet. Both sides commit war crimes incessantly.
- The MachineGames Wolfenstein series - It's 1960, Jim, but not as we know it. The Nazis used crazy super-technology to win World War II and grind the Free World into dust by 1947. The games pull no punches in its depictions of the Nazis' ideology and the kind of waking nightmare they would turn the world into if they were free to reshape it as they saw fit.
- Dark Souls
- Conan the Barbarian - Takes place in a fictional time period after the sinking of Atlantis but before the historical record began. There are monsters and villains everywhere, all magic is black, and the few cities are run by maniacal sorcerers and other unsavoury types. Conan usually only barely survives his stories through wit and dumb luck rather than might, and he certainly cannot change the world, not at least until he becomes the good king of Aquilonia.
- Dark Sun
- Delta Green - Earth and mankind exist in a tiny flickering firelight of sanity and civilisation that can (and inevitably will) be snuffed out by alien gods and forces of madness. You play as the clandestine agents of the US government tasked to investigate and combat this phenomena. Few people in Delta Green live to retire, and the most common retirement plan usually involves a bottle of whiskey and their service pistol.
- Dwarf Fortress
- Nineteen Eighty Four / I Have No Mouth And I Must Scream / Xeelee Sequence - All three are strong contenders for the most Grimdark story ever put to paper, experts are currently divided. The first takes place in a (possibly) post-apocalyptic Earth split between three totalitarian superpowers that are constantly at war despite sharing the same nihilistic ideology, and the hero is an ordinary man who gets captured, tortured and thoroughly mindfucked by the police into accepting the rule of the Party. The second takes place in a post-apocalyptic underworld city where a psychotic supercomputer tortures the last four living people and brings them back to life if they try to kill themselves; the protagonist "wins" by mercy-killing the other three but his moral victory is tempered by the fact he is trapped forever at the mercy of the machine. The third takes place in a nightmare hellscape where the entire universe is dying between a cosmic war of two god-like races, whilst the human race has degenerated to such levels of bastardry, that the actions of stripmining entire galactic superclusters or committing a xenocidal killing-spree across the universe that stretched for millions of years is a mere dip in the ocean. There is no hope or salvation, heroism is not only dead but outright outlawed, absolute surveillance and total control due to mass time-travel usage, as an incalculable amount of human child soldiers would die for nothing. Meanwhile the surviving races are fighting tooth and nail, killing each other as they are trying to escape a reality that is collapsing in on itself.
- The Sims - Pretty self-explanatory. The world is generally nice to live in and stories are more about your Sims' living one day at a time than anything else.
- Most Tycoon games
- Mass Effect
- The Commonwealth Saga
- Eclipse Phase
- The Culture - Futuristic novel series by Iain M. Banks, set in a utopian society based on socialist and anarchist principles achieved by post-scarcity technology (space hippies whose words are backed by star-system busters, this lot are probably the only fictional sci-fi civilization that would beat the Imperium hands-down in a war). The protagonists are usually Special Circumstances, agents of the closest thing they have to an intelligence division given license to operate outside of their laws and morals to uphold the Culture way of life.
- Scarred Lands
- RWBY - The result of Sailor Moon and Bloodborne having a drunk fling, it subsists on a steady diet of Rule of Cool. You take four cute teenage heroines and watch as the grim, behind-the-scenes reality of their glamourous high adventure world beans them over the head repeatedly. Because they are just rookies who don't matter much in the grand scheme of things. Then they come back with a vengeance and it becomes pure Noblebright instead.
- Doctor Who - It's a time travel show where the protagonist is a millennia-old alien who has seen and done some truly incredible shit in his time, but cannot overtly alter the flow of history or even build close relations with his human companions. He just saves the day and goes off to another planet.
- Most of Zeus' flings with mortals (from the gods' perspective)
- The Lord of the Rings - If Warhammer is the platonic ideal of Grimdark, LOTR is the platonic ideal of Nobledark.
- Mass Effect - A universe where there are millions of heroes, and of course, Reaper Grimdark.
- Terminator - "No fate but what we make".
- Fallout - Especially New Vegas, oh boy, New Vegas. The Independence ending is basically the story of how a wasteland courier dug their way out of their own grave and brought down two post-apocalyptic superpowers through sheer force of will and character.
- The Iliad
- Most Batman stories - Yes, Gotham sucks and yes, Batman is a dark character, but he is also a deeply idealistic hero (refuses to kill, believes in the inherent good of people and the human spirit). Which is why putting Batman in Grimdark tends to really not work.
- Warhammer novels like Ciaphas Cain and Gaunt's Ghosts. Especially ones where the protagonists are ordinary people like the Imperial Guard rather than the superhuman, galaxy-bestriding Space Marines.
- Exalted - Encapsulates the nobledark spirit for RPGs. "The world sucks. You have the power to fix it. Try not to fuck it up worse."
- The Chronicles of Narnia
- Forgotten Realms
- Star Wars
- Most Marvel movies, except the one that is really infamous for not being this
- The Odyssey
- And of course, Star Trek - The platonic ideal of Noblebright.
