大和高田での写真展からの帰り路 富雄川を北上してると西も東も面白い空♫ 東の空は反薄明光線(裏後光)。 2024年9月10日撮影

どちらもiPhone～ なぜかピンボケ撮れてて ピントしっかりより良い感じだったのでこちらで✨

Two years ago, I went grocery shopping with my dad. I remember walking out of the store, looking over to my right, towards the clouds, and being amazed at what I saw. It's beautiful. Haven't had anything like this happen to me before, nor afterwards.

Anticrepuscular Rays: A Rainbow Fan over Spain Image Credit & Copyright: Julene Eiguren

Explanation: Yes, but can your rainbow do this? Late in the day, the Sun set as usual toward the west. However, on this day, the more interesting display was 180 degrees around -- toward the east. There, not only was a rainbow visible, but an impressive display of anticrepuscular rays from the rainbow's center. In the featured image from Lekeitio in northern Spain, the Sun is behind the camera. The rainbow resulted from sunlight reflecting back from falling rain. Anticrepuscular rays result from sunlight, blocked by some clouds, going all the way around the sky, overhead, and appearing to converge on the opposite horizon -- an optical illusion. Rainbows by themselves can be exciting to see, and anticrepuscular rays a rare treat, but capturing them both together is even more unusual -- and can look both serene and surreal.

Anticrepuscular rays are optical phenomena that appear as converging beams of light on the horizon opposite to the Sun. They are similar to crepuscular rays but occur on the antisolar point due to perspective, making parallel sunlight beams seem to converge.

Anticrepuscular Rays: A Rainbow Fan over Spain

A rainbow is pictured over the sea between an island and land. A series of light rays appears to connect the horizon to the rainbow.

Anticrepuscular Rays at the Planet Festival, 2024-07-19

For some, these subtle bands of light and shadow stretched across the sky as the Sun set on July 11. Known as anticrepuscular rays, the bands are formed as a large cloud bank near the western horizon cast long shadows through the atmosphere at sunset. Due to the camera's perspective, the bands of light and shadow seem to converge toward the eastern (opposite) horizon at a point seen just above a 14th century hilltop castle near Brno, Czech Republic. In the foreground, denizens of planet Earth are enjoying the region's annual Planet Festival in the park below the Brno Observatory and Planetarium. And while crepuscular and anticrepuscular rays are a relatively common atmospheric phenomenon, this festival's 10 meter diameter inflatable spheres representing bodies of the Solar System are less often seen on planet Earth.

Oh sure, you could easily just handwave most things and blame it on magic, but you don't have to for all of them!

For something like the seasons, it could be as simple as having different names for things. Maybe instead of dividing a year into four seasons, a culture divides it into six. You can still have summer (peak heat) and winter (peak cold), but the warming-up and the cooling-down periods each have two parts, with very different cultural connotations. That way you can have a Midwinter Ball as well as a Thaw Cookoff and a Hatchtime Egg-Painting Competition, with some time still to go before summer.

Jewelry can absolutely be anything we find pretty. That doesn't even need to be otherworldly, as long as there's some creativity put into it. I think the inclusion of that one on the list is to get people thinking about the possibilities instead of just sticking to the most obvious and over-used examples. I've seen some photos of gorgeous gowns decorated with iridescent beetle wings. Peacock feathers are a known quantity when it comes to spectacular birdstuff, but there's a ton of other possibilities there. The world is full of pretty things; as you said, it's all a matter of how valuable any given culture considers them to be.

Seeing an aurora near the equator would probably have to be a magic thing, but there are Southern Lights as well as Northern Lights, and all sorts of other atmospheric phenomena that aren't as famous. Maybe the story could include light pillars or anticrepuscular rays instead.

For domesticated animals, we do have plenty of real-world possibilities for pets other than cats and dogs. I don't think that entry in the list was as much about treating wild animals as like tame ones, as much as it was about inventing fantasy animals but treating them exactly like cats or dogs. While a shoulder dragon that behaves like a cat is adorable and lovely, there's untapped potential for going other routes. What about a dragon that overgrooms like a bird, or gnaws through the back of the snack cupboard like a hamster? A domesticated unicorn that uses its horn to unlock gates like the most troublemaking goat? Or some wholly made-up creature with behavioral quirks that can't be pinned on any existing animal?

Books are a tricky one. I wrote about a culture that uses knot-tying as a form of writing (inspired by quipu), though that does have limitations. Magic will probably have the most possibilities. Even if the end result does turn out to be Books But Different, or some form of Magic CDs, a bit of flavor will at least make it interesting. Maybe one culture uses pixies as scribes, and they write by dancing across the page like a tiny version of the Dinotopia dino-print alphabet. Maybe the common folks use clay tablets, pressing the edges of a stylus into the clay when wet, then drying it -- for an extra fee, they can have it enchanted to recite the message aloud when read or it can include a mental imprint so the reader gets a thought from the writer when they read. There's lots of leeway for making things interesting, even if they're not fully original.

I love thinking about stuff like this. Creative approaches to common things, clever explanations, surprises instead of everyday norms. Sure, you could just say that the wizard has a blue cat that teleports, and that's very cool, but you could also say he has an enchanted hairbrush that needs to brush something daily or else its bristles will overgrow, and he has to remind it to use the bundle of horsehair that's tied to the coat rack for just that reason. (Or the wig in the spare room. Or the stonework outside. Just not the wizard's hair; that's thinning enough as it is.)

Small fantasy worldbuilding elements you might want to think about:

A currency that isn’t gold-standard/having gold be as valuable as tin

A currency that runs entirely on a perishable resource, like cocoa beans

A clock that isn’t 24-hours

More or less than four seasons/seasons other than the ones we know

Fantastical weather patterns like irregular cloud formations, iridescent rain

Multiple moons/no moon

Planetary rings

A northern lights effect, but near the equator

Roads that aren’t brown or grey/black, like San Juan’s blue bricks

Jewelry beyond precious gems and metals

Marriage signifiers other than wedding bands

The husband taking the wife's name / newlyweds inventing a new surname upon marriage

No concept of virginity or bastardry

More than 2 genders/no concept of gender

Monotheism, but not creationism

Gods that don’t look like people

Domesticated pets that aren’t re-skinned dogs and cats

Some normalized supernatural element that has nothing to do with the plot

Magical communication that isn’t Fantasy Zoom

“Books” that aren’t bound or scrolls

A nonverbal means of communicating, like sign language

A race of people who are obligate carnivores/ vegetarians/ vegans/ pescatarians (not religious, biological imperative)

I’ve done about half of these myself in one WIP or another and a little detail here or there goes a long way in reminding the audience that this isn’t Kansas anymore.

Attack on @fallenclan >:D

Had some silly fun trying to figure out how to make the crow wing shadows look like crowflame had 'wings' while also making the sky in the background have a setting-sun like colour to imitate fire. This led me to discovering anticrepuscular rays! fun little guys.
