What remarkable light sources does (or doesn't) your world have?

Humans actually glow in a color only griffons can see. The griffons never told them, and used the fact that humans didn't know about it to their advantage in the many attacks on humans. Imagine trying to hide from something that is already known for its impeccable eyesight, not knowing you're glowing in a color it can see. To this day, that is a well-kept secret of griffons, as even half humans emit a faint glow. There is no malicious reason for why griffons hide that fact, they just don't like humans. At all. So they want to know who is how much human, so they can avoid that person. If they consider them a person, that is.


Quantext609

Has any human gotten close to cracking the code?


Kartoffelkamm

Not really, since they went extinct some time before the events of the story I'm writing in that world. But most humans that came close to figuring it out were quickly confused with the typical "I can smell your fear" thing. Which isn't even that weird, because dwarves can hear precious metal ores.


DoomTay

Unrelated, but there's a guy here who has been showing stuff for a griffon-centric world. For a second, I thought you were that guy


Kartoffelkamm

I see.


Martinus_XIV

Why the bad blood between humans and griffons?


Kartoffelkamm

Generations of slavery and abuse. Humans didn't recognize griffons as sentient beings, and since the griffons were upset about that and retaliated, sometimes with lethal force, humans decided that that gave them the right to be d*cks to griffons.


bigbogdan98

Nothing remarkable , unless you count the glowing plants that can be found under and above the ground , candles , torches , oil lamps , we have 3 moons in the sky but on different orbits so we have only 1 at night with another 1 during the day and the 3rd one can appear at sunset or sunrise , the life goddess who took the shape of a sun and can be seen as a large star in the night sky but doesn't give too much light , dwarves in their entirety and some humans have electricity , no one uses magic for light and about the people staying up , depends .


Brumbleby

So, nothing remarkable, then? 😜 Serious posts only Haha, wonder what those moons do to the tides


bigbogdan98

Well , i want to keep it "normal" and "realistic" About the tides , I imagine them a bit higher and faster since one moon is a bit bigger than our own and the other 2 are smaller + they are at a bigger distante than our own . The same about the earthquakes and the vulcanic activity , a bit bigger but not big enough to be a nuisance .


Brumbleby

Cool. Thank you for sharing 😊

Nod is a continent located in a giant cave, so obviously there is no sunlight there. Instead, the primary light source is the manna roof. Manna is a bioluminescent, mushroom-like plant that covers the roof of Nod, and look like stars glowing in the cave's black ceiling. The manna is in sync with the rising and setting of the sun, for when night falls on the surface the manna will fall out of the roof in clumps and the cavern becomes much darker than it is normally, although some manna plants will still remain. And in the morning, the manna will regrow on the roof, and the cycle will repeat for the next day. This defines the day/night cycle of Nod. Nod even has its own summer and winter solstices, as during the summer solstice the manna grows very thickly in the day, while during the winter solstice there will be barely any growing at all and the nights are pitch black. Mannafall is an important part of replenishing the nutrients of the soil in Nod, acting as litter than makes the soil fertile as it decomposes (fun fact - manna decomposition is actually odourless), and fallen manna is a major part of the diets of nomads and poorer village-folk since it's so easy to get a hold of - some people even live off of it. It tastes sweet and soft, like marshmallows.


Brumbleby

Do these people know about the sun?


JA_Pascal

Nodians are descended from people from the surface and both writing and oral history recites the existence of the sun, moon and stars. Understandably however, confusion quickly began to spread as to what the celestial bodies actually were and if they even existed, so you have some pretty weird misconceptions and ideas bouncing around about them.


Martinus_XIV

I'd love to hear some of these misconceptions...


JA_Pascal

[I talked about them in this comment thread.](https://www.reddit.com/r/worldbuilding/comments/pjjedl/what_do_people_think_of_the_stars_and_the_moon_in/hbxxvz2/)


Quantext609

Does Nod ever export the stuff to other countries? It sounds very useful.


JA_Pascal

Nod is a continent and got sealed off from the surface centuries ago, so there's no contact between Nod and the surface anymore. Even if there was, manna goes bad pretty quickly so it was never an international trade good. Sometimes it gets traded to desert-dwellers who live in areas with very low amounts of manna, though.


CodyLabs

Where does the manna get it's energy for such rapid growth? Does it leech off chemicals from plants in the ground above?


JA_Pascal

People don't know where the manna gets its energy from, or how it grows so quickly. A few gods do but it's secret knowledge.

Like most things dwarvish, describing how a clanhold operates starts with beer. The typical dwarf consumes about 2,500 calories a day. Miners require 2,000 more calories per day. There’s 2,000 calories in one gallon of dwarvish stout, which requires 2.5 pounds of barley, hops, yeast and dwarven brewing talent per gallon. If 20 percent of dwarves are mining, that’s 160,000 dwarves, and at 300 days a year, that’s 120 million pounds of grain. How in the hell do dwarves grow millions of pounds of grain on a mountainside? They don’t. They grow it *in* the mountain. Beneath the surface, the center of dwarvish clan life is the *sonkamen*, or sunstone, placed at the center of an intricate and perfectly angled group of mirrored trays for growing food in a *garündůma*, or green room. A sonkamen is a magical device which can be enchanted by 6th level or higher clerics of Moradin, requiring a diamond worth at least 1,000 sovereigns. A sonkamen holds a permanent Daylight spell, which follows a normal day/night pattern of 12 hours. It can be commanded to turn on or off by anyone with the command phrase. Sonkamen are hung from a chain in the garündůma, a perfectly spherical room exactly 60 feet in radius, into which trays bearing soil have been packed from floor to ceiling. The trays are fed from water pipes built into the walls. And the outside surface of the room that isn’t holding plants is plated in mirror-finished silver, allowing the light from the center – with magical assistance from the spell – to reflect and strike every plant in the room. The silver alone is worth 10,000 sovereigns. Clans often describe their strength by the number of garündůma they possess. The garündůma provides its own temperature regulation, and because it has no seasonality, crops can easily yield three harvests in a year. Each harvest produces 3 acres worth of regular crops – peas, beans, cabbage, turnips and in particular the dwarvish yam that is a staple of the diet. It also produces, through the crazy upside-down cultivation techniques developed over centuries, another 3 acres of dwarvish barley, at 600 pounds per acre. The yield of the standard crops provides enough food for two people to survive a year without any other sustenance. A harvest of 1,800 pounds of barley becomes 720 gallons of stout dwarvish beer, enough for two miners to work for a year.

###🌫️The Outpost⚙️ Bioluminescence is a common cheap form of lighting in many parts of the world due to it requiring no power and the ability to reproduce on it's own. There are variants of bioluminescent light sources made by both red and green spirits. The former come in barnacle like creatures with glowing "legs" and the latter as moss and weeds that have glowing leaves.


Brazyer

**Mythria** It is one of the daily duties of priests in the Luna Cathedral to maintain the 'holy flames', sconces and braziers alight with green fire to represent the glow of the Emerald Moon. These verdant lights are situated around the main altar, and at the entrance, and gain their hue through a combination of kindling gathered from the mystical Greenwood forest and Viridian Salt. These holy flames are temporarily extinguished during times of great mourning, like at the end of a Pontiff's life, or during times of remembrance, such as the anniversary of Saint Sirius' death and the 'Final Crusade'.


MysteriousMysterium

832 While electric light is available in this world set on earth in the 2240s, Aether as the energy distibutor (blue liquid) also glows when charged with electricity.


sifsand

The Xamoyan tribes use fire, specifically campfires and torches. They are a stone-age tribal people after all. It also doubles as a weapon and cooking tool.


Brumbleby

So, fire good?


sifsand

Fire very good.

The people of Unum have been biologically-engineered several times throughout their history from the golden irisis of the Vahlen, placed upon them as a mark of ownership by the 'god' Nox, to the gigantism of the Neo-types. However, the oldest modification, and the one history has forgotten the origin of, is Unumese Acausal-Biology (A-B), a series of cell sized nodes that runs along the nervous system of every human on Unum. While the most interesting ability A-B provides is allowing its users control over all four fundimental forces of nature (electromagnetism, gravity, strong & weak necular forces), the most relevant to this discussion is the bio-luminescence that is something of a 'side effect' of 'casting' Acausal-techniques as the users A-B produces waste heat and converts it into photons. Unumese bio-luminescences creates distinct patterns as it illuminates the user's nervous system from the inside, and at particularlly high n² percentages the glowing patches are visible in broad daylight.


Runitari

There are no celestial objects since the world exists on the border between reality and the astral. Instead the horizon of the Dark Ocean gives off a subtle light that gives a gentle glow to the world at night. Also there are a variety of plants that have absorbed primal energy and molten materials to become a radiant tree or plant within the caverns of the world.


CrunkBunni

During the night the Morningstar Academy is lit up by wall sconces in the shape of flames, each with a different design, carved from wood. They are enchanted each night to behave like fire and release light with minimal heat, to protect the wood. Some say that Gaia Shrinehands (mages from the Gaia Shrine) can use their magic to embue the flames with the properties of different plants. that a sufficiently determined Shrinehand could use the soft light to disperse an odourless poison into the air... But then again, theres no way anyone would do that.

Bifrons On the tidally locked planet of Bifrons, the sun is always up for half the planet. As a red dwarf it produces a much weaker light than Sol... except when it's flaring, which is a common enough occurrence that everyone has a flare shelter built into their homes. Over on the planet's Nightside, the presence of a "nearby" star cluster means the clear night sky is about twice as bright as Earth's on a full moon. But for cloudy periods, the few nations that live on the Nightside rely on glowrods: glass tubes filled with chemicals extracted from bioluminescent fungi.


RandallBates

There is on the southern nation of the continent of Haxii glowstones that are not rare but not that common, other than that there is some people whose powers can lead to various source of lights, but the other alternative lightsource other than torch or oil lamps and candles are the Gaz on the nation of Victoria using unknown methods with the flames of dragons to obtain this gaz that is used for various means the main one being the illumination of streets and factories that permits night work for the war effort


Martinus_XIV

the continent of Sylarbora sits entirely above its planet's permanent cloud cover (to them known as the Sea of Mists). As such, the sun is visible all day and the three moons are clearly visible all night. They are used much more directly to tell the time and to navigate than they are in our world. There is also Luminite, a mineral that contains Lumen energy. Luminite crystals infused with Lumen glow dimly in a soft yellow, magenta, viridian, deep blue or silver. The crystals can be used to build Lumenic devices which can i.a. grow brighter and be used as lamps. Also, Sylarboren humans have glowing eyes. They aren't bright enough to shed light, but they can be seen in the dark.


DwayneTrawick

Simple, radiance lamps. These use radiance stones (a clear crystal enchanted with light energy) which are either removed from the lamp and recharged by the local mage, or (if you live in a big city) wired into the energy grid.


Silverdragon701

Angels and Demons both emit colors only visible to cats, and humans who have eaten Photosygia Paxis, a mushroom found on church steeples Geld, the color of Angels, has been described as a golden honey-blue, and is said to bring a sense of deep calm and serenity, like floating on the surface of the sea of creation. Afror, the color of Demons, is described as a blinding, burning red shadow, and inspires deep-seated anxiety and dread.


CreeperTrainz

While the sunlight on Aldreas is almost identical to that on Earth (if a little whiter), moonlight is a much more impressive sight. As Aldreas is a moon and orbits the super earth Tal very closely, moonlight (or rather the light reflected off of Tal) is nearly 1000 times brighter than the moon, with Tal itself appearing twenty times larger in radius than the moon does on Earth. This means that on the side permanently facing Tal (known as the Nearside), nights can be as bright as as a cloudy day on Earth, depending on where you are and what time it is.


Brumbleby

I've been thinking about bioluminescence and how someone might harness it.


DoomTay

Dwarves make use of crystals that emit light. Great for navigating caves (Yes, the whole idea is a Bionicle homage)


CodyLabs

The Keslersphere. The machine war left so much space debris in orbit around planet Vinland that it can be seen as a glittering second layer of stars, flying in every direction, visible for an hour or two before sunrise and after sunset. The sparse human colonies on the planet enjoy a rather lower-tech existence without internet or long-range communication, as the speeding debris would quickly shred any attempt at a satellite presence.


TheIncomprehensible

I have two worlds, both with their own unique light sources. In the southern continent of Soltarra, there are bioluminescent plants and fungi that emit a blue light. Plants are seen above the surface and are blue because their equivalent of chlorophyll (which is the pigment(s) that gives plants their green color) happens to be blue. The light it emits tends to be rather dim. On the other hand, fungi grow below the ground and grow quite brightly, providing enough light to be used as a food source for plants below ground. Also on Soltarra, in the country of Orethia, there is a species magic-based beings called Wraithkin. They are composed entirely of magic, and if they are composed of the right magic (like fire magic) then they can give off natural amounts of light. Orethia also has a lot of magic, and some of the magic of their human mages has the side effect of producing light. Some animals will also produce their own light, usually due to indirect magical means, although this one is much less interesting since it's usually a matter of "this animal is naturally on fire" or "this animal glows". Far north, on the SMC, there's a mineral called a moonstone that gives off a light similar to that of the moon. However, it's not entirely useful because the humans there have artificial light that's considerably brighter. > Do people go to bed at sundown or stay up reading with a candle? With this sentence, I'm assuming you're also looking for unique uses of existing lighting rather than just unique lighting in general. Southeast of the SMC, there's Duskala. The species on the island has a unique attribute where they change form at night. Transformation can include any number of things like gaining limbs or altering skin. Transformations happen when the sun rises and falls and are rather disruptive when they happen, so the Duskalans have timed their sleeping habits such that their transformations happen while they are sleeping for the greatest convenience. ____________________________________________________ In my other world, it's split into a human realm and a dream realm. The dream realm looks a lot like the human realm (complete with its own copy of Earth), and the dream realm has a permanent purplish haze with an unknown light source. No one knows where the light is coming from, it just is. The most common theory is that the dream realm is actually an entity of its own that is capable of providing its own light without any assistance, although what the entity is currently isn't known. The dream realm houses beings called spirits. I won't get into too many specifics about spirits (for the gist of it think of a cross between Luigi's Mansion ghosts with Stands from Jojo's Bizarre Adventure), but the part that's related to light is that they emit some light when they travel to the human realm. How much is dependent on the spirit and how long they have stayed in the human realm on that particular trip to the human realm (they start out bright and dim over time), but the light is always unusual.


TrezVenator

The rotting fumes of The Gods Corpse collect in small cavities inside the body, giving a faint light all 24 hours a day, granted the corpses skin is slightly translucent so sunlight reach's through at noonday to brighten it up a bit. So rotting fumes interact with air to create bioluminescence/chemiluminescence gas (It's all pretty toxic, thankfully lighter than air)


kairon156

In my world magic is very common. Some people simply cast sight magic to allow them to see in low light, while others use rune magic on objects to make them glow while the rune it's self is being charged. Magic gems give off a faint glow when their charged so they can be used as a night light, just bright enough to see the shape of objects around you. I have a vague idea for sun and moon stones but IDK what their function will be just yet. --- Awesome question by the way, I never gave light sources much thought sense technology exists in parts of my universe too.


Fire-Fly_

Not so much a light ‘source’, but in attempting to imitate the crystalwork of the Kalkarans, Valean engineers accidentally created a crystal which refracts light within itself in such a way that the chances of it escaping are *incredibly* low. Basically, you can leave it out in the sun all day, and then if you take it into the dark *just* enough light to properly see by will escape. The earliest versions only lasted a few seconds at best, however through refinement, as well as strategies to have multiple working together, it’s now not uncommon to see these crystals used as streetlights. However, with the advent of electric lighting, they’re quickly falling out of fashion


Inflatable_Bridge

The Araen live in caves, and grow a certain type of moss that glows. When processed correctly, they can make *yiaor klaiossan*, a *bottle that glows*. These emit about the same level of light as your average light bulb, and are used everywhere in the Araen cities. Why don't they use fire? They don't like fire. In fact, they hate it and are afraid of it. The Earthmen on the other hand have mastered fire, being able to change its color with certain powders and make them grow and shrink at a moment's notice. They are the only Riadan species that has mastered fire like this, and one of two in the entirety of all worlds. Humans and Herunds simply light their stuff with fire, though the Herunds also occasionally use the glowing bottles instead of torches and candles. Not always though, as they don't know how to make them themselves.


Soggy_Memes

The Alrûnai have wind and water power that gives them their electricity, plus the natural light of their twin stars. These are red dwarf stars, so they're more of a dimmer orange than our sun and are much, much older. This gives Alrûn a slightly warmer, duskier lighting than places that orbit more normal, main-sequence stars. Yandij has one sun, and it is a main-sequence star much brighter than our sun. Yandij is very far away from the star, far enough that the world is quite cold by nature. The sentients of Yandij (who I've re-written and developed more thoroughly since I last mentioned them, and that means all the species+subspecies) have 3 main sources of power: Wind power, water power, and steam power. This steam power is made by harvesting dew and heating it up to create steam (this tech was also used by the evil Matriarch we see on Yandij in the project they appear, in combination with other chemical technology, to create the chambers for the Interspecies Breeding Project). The Tadibzi people live on Galramlia, an incredibly hot desert world that orbits two large white stars. They, as such, have a lot of solar power, but they also operate on a lot of sand power. This works in a similar method as water power, turning sand in massive turbines to create friction, therefore creating heat, which they turn into energy using other technologies of their own creation. They rarely let the secrets of this sand power out to others, and only 4 offworlders know of its full design.
