Penumbra W.A.V.E.

Penumbra W.A.V.E. thicc lore

Setting: A large purple gas giant orbits a rather ordinary white star. This planet has six moons of various sizes that all orbit it.

All of these moons differ in composition and environment but share one commonality: the presence of a mysterious iridescent crystalline material in the surfaces and atmospheres of each. Dubbed "moonstone", this material forms the backbone of society on the main moon, Mykaris.

Day/night on the moons is asynchronous due to the gas giant occasionally blocking the sun. During "nights" on any one moon, starlight refracts through the crystals on any of the other six that are visible, bathing the moon in bright, iridescent Moonlight.

Of the six moons, only 3 are known to support life. Mykaris is the most vibrant, followed by Palama, the largest, and Myacumma, the closest to the planet.

Travel between the moons is special. Spacecraft have not yet been developed on most of the moons, so travel is accomplished through Moon Gates: magical doorways located in hard to reach places on each moon. Travel through these is exhausting, and depends on the physical distance between the moons at the instant of travel.

Moons:

Mykaris is about Earth sized, with one ocean taking up about 40% of the surface. Most of the land is rocky desert or mountains, with very little forest.

Mykaris is populated by multicolored humans (mostly purple, silver, and light blue), who call themselves "Mykarians". They are ruled by a King (currently King Ekkaj, of the House of Bil) who lives in the Mykarian Citadel.

Mykarians have mastered the art of harnessing Moonlight. Their biochemistry and diets infuse their bodies with microscopic Moonstone crystals; and they are able to use powers of light and darkness, and in some rare cases even generate or control their own Moonlight, using Moonstone-infused weapons.

Mykarians harness this power in 3 major ways. The first is focused application of Moonlight; this form is called Penumbra. The second is the opposite, complete and total pulling away of all Moonlight in a vicinity, letting the force of the resulting darkness do the work. This is called Umbra. A third form exists in ancient writings; the usage of both of these concurrently, and in perfect harmony. Light and dark waveforms overlap precisely to create unimaginable power; this is called Antumbra. This form is exceedingly dangerous to even attempt, and none have succeeded in centuries.

Mykarians have an army, which mainly defends the cities and their surrounding lands from khyrongs, great beasts that roam the deserts. Think centaurs mixed with crocodiles.

Palama is the largest moon. It is largely covered in ice and ocean, with dense tundra on land. It is also volcanically active, with great mountain clusters surrounded by metallic minerals.

Palama was home to the Relamp, another humanoid species. Relamps were rather reptilian in nature, cold-blooded with scaled tentacles in addition to their arms. They learned to convert Moonlight into electricity, and used this knowledge to travel between Gates more easily.

Relamps used to travel between Palama and Mykaris in antiquity, but as of the Day of Storms none have since been found. Expeditions to Palama find only abandoned ruins of their temples and fortresses, though it is commonly suspected that a few remain in hiding on the uninhabited moons.

Little is known about Myacumma. Its inhabitants, a race known only as the All Moons Clan, discovered spaceflight and left the planet before it was consumed by a calamity. It is unknown whether this was caused by them, and will likely never be known, as all Gates to Myacumma have been destroyed.
