80+ Astronomy Features For Fantasy Worldbuilding50 min read

Comets, eclipses, and cosmic wind! Welcome back, Outlander, to the 15th entry in Mythic Ecology, my series on how learning real-world landscape features can enrich our fantasy worldbuilding and storytelling. In this post I return to my minimalist framework for Dungeon Masters, Game Masters, fiction writers, and similar worldbuilders to merge the realms of general myth and geomorphology. Last entry I took a look at Rock Formations. As I resume my journey sketching a framework for designing Yridia, my unique D&D 5e fantasy world, let’s learn some rock formations, with a visual guide. With the deep space themes of Spelljammer set for official release for D&D 5e, I figure this one might be especially helpful!

How does one interact with such astronomy aspects in normal D&D 5e play? Here’s some ideas, which I will tag where relevant:
1. Magical Means: Arcane & Divine Scrying (e.g. the Scrying, Legend Lore spells), deific powers (e.g. Cleric’s Divine Intervention, the Wish spell), teleportation (e.g. the Teleport, Teleportation Circle) planar portals (e.g. Gate, Plane Shift, Astral Projection spells).
2. Spelljammer Vehicles: spacefaring vehicles in the forthcoming Spelljammer material.
3. Magitek Telescopes: a bit of a deus ex machina of magic-powered optics comparable to some variety of industrial telescope lenses, perhaps powerful artifacts.

All the images herein I use for educational and entertainment purposes, I claim no rights to any of them. For corrections or content removal requests, hit my contact page.

Let’s revisit my minimalist framework for my worldbuilding. The six archetype tags with which I will flag all the various real-world land features in my Mythic Ecology Series:

1. Settlements: habitable regions of either Work or Play, Familiar or Exotic, offering diverse narrative functions: a Day in the Life, Home Base, Personal Reasons, Gathering Supplies. Can subvert tropes with Ruins or Escape.
2. Omens: sensational, temporal, or particularly pointed features that offer narrative functions of forshadowing, and good or evil portents. Can subvert tropes with a Wild Goose Chase.
3. Overlooks: sites of magnitude and grandeur, living monuments which can function narratively for finding resolve, invoking spirits, or as a Call to Adventure. Can subvert tropes with Dread or Betrayal.
4. Passageways: transitional journeylands, including magical portals, functioning narratively for initiation and return, thresholds and tests, shortcuts and setbacks.
5. Abyss: a void or confined space presenting scarcity or temptation, desperation and danger. Can subvert tropes with a Timely Rescue or Secret Refuge.
6. Battlegrounds: sites fit for epic, sprawling encounters and climax conflicts. Can subvert tropes with Alternative Solutions.

Feel free to submit your own ideas, or draw outside the lines. Alright, let’s see how astronomical phenomena fit in.

TIP: Since most of this entry’s features function as omens, if you want some prophecies to go along with them, I use the free D&D random prophecy generator tools from Fantasy Name Generators, Chaotic Shiny, and Springhole.

Folklore associates it with increased power of spells and rituals during this time, sometimes prohibiting those as dangerous. Colloquially, can refer to a moon with a temporary black-ish hue.
[Omens, Overlooks]

Blood Moon – the reddish coloration of an eclipsed moon. Arises due to sunlight refraction in the atmosphere scattering green to violet wavelengths.

[Omens, Overlooks]

Major Lunar Standstill – when a moon’s range of declination, and consequently its azimuth range at moonrise and moonset, reaches a maximum: highest or lowest. Viewed from the middle latitudes, this moon’s altitude when it contacts the observer’s meridian changes in only two weeks from highest to lowest above the horizon (either due north or south, depending on hemisphere). Likewise, its azimuth at moonrise changes from northeast to southeast, and at moonset from northwest to southwest. Associated with cultural architectural alignments and megalithic monuments.
[Omens]

Planetshine – when a planet reflects sunlight that dimly illuminates the dark side of a moon, while that moon appears as a narrow but waxing crescent to observers upon the planet.
[Omens, Overlooks]

Saber’s Beads – a broken arc of illuminated lunar mountain peaks, generally within 24 hours of a New Moon. Rarely observed due to the varying of lunar libration and sun proximity. Resembles moments just before and after total solar eclipse.
[Omens]

Supermoon / Perigree Syzygy – a Full Moon or New Moon which coincides with perigree, when a moon comes closest to its planet in its elliptic orbit, resulting in a larger-than-usual apparent size of the lunar disk to an observer. Opposite of Micromoon.
[Omens, Overlooks]

Micromoon / Apogee Syzygy – a Full Moon or New Moon which coincides with apogee, when a moon goes farthest from its planet in its elliptic orbit, resulting in a smaller-than-usual apparent size of the lunar disk to an observer. Opposite of Supermoon.
[Omens, Overlooks]

Wet Moon / Cheshire Moon – a visual phenomenon where a crescent moon’s “horns” point up at an angle, away from the horizon, similar to a smile or a bowl. Occurs when a crescent moon sits low above a planet’s horizon, at a point roughly above its sun’s invisible position below that horizon. Happens more often in the tropics.
