Kadaun & Masera
The Ancient Planet, known as Kadaun in Didenki, is the largest inhabitable planet yet discovered.
It's also the center of its own solar system. Cool, huh? There is no literal night on the ancient planet, because its Omynic surface generates light and energy. There are, however, differences in light which they use to separate “daylight” and “dimness” or “rest.”
Kadaun is located in a galaxy not far in proximity from the Milky Way, but rather, far in dimension and reality.
All matter on Kadaun is made from Omyn Atoms, and four genetic Omyn-types - Enfamuy, Arlomuy, Finomuy, and Lyfamuy - originated there.
Kadaun is home to three ancient races, and in modern times, a fourth emerging race. They are the Arlomin, Vfinom, and Senfamin. The fourth is the Gindeki, outcasts who bear Lyfamuy, yet have not been banished to Masera for unknown reasons. All speak ancient Didenki.
Masera is one of Kadaun’s seven moons, yet it is the only one able to sustain life.
Like its mother planet, Masera is entirely comprised of Omyn atoms. However, Masera does not produce its own daylight. It absorbs Kaduan’s natural light.
It’s said Masera had no soul-life of its own, but rather, convicts—or in some stories, rejects—from Kadaun's three races were exiled there. Among them was the notorious Lyfel, a Senfamin said to have brought evil and fear to the Ancient Planet.
From the children of these three races emerged new kingdoms and peoples: the Amesytins, the Somorrins, the Oranu, and the Trajonyts.
The wildlife of Masera is generally violent and hostile. Plants are often poisonous and/or carnivorous. Because of this, Maseruy civilizations are under constant vigil and build walled fortresses. They spke Maseruy Didenki before Masera was destroyed in The Great Conquest.
Earth & Erbede: "The Sisters"
The Shadow Planet Theory, developed by leading Erbedian minds, states that Erbede and Earth are corresponding counterparts revolving on opposite poles of the same orbit around the same respective sun in the Milky Way Galaxy.
This means: Erbede and Earth never meet because they are fixed on the opposite sides of the same sun. A fact proven by their corresponding constellations.
The two planets are laced together via Omyn Spacial-portals which naturally open and close regardless of Omeing prevention or origin in specific regions such as caves and aquatic trenches.
Erbedians knew to look for earth because their verbal history contains accounts written by Erbedians who traveled to and from Earth just as they traveled between the other planets before The Great Conquest. These two planets were finally reunited in 0532 aa or 1946 a.d.
Earth is much larger than Masera, much smaller than Kadaun, and slightly bigger than Erbede. Despite its 8 billion people with thousands of languages and notable topography, it is almost entirely Omynless and inhabited solely by Humans.
Erbede is just smaller than Earth and also absorbs energy and light from its Solar System’s local sun. Though its geology and atmospheric makeup aren’t Omynic, they neither foster nor inhibit Omyn lacing in organic life.
Every known people group has inhabited Erbede, though it orignially had only four native peoples.
The Blue Moon
Until recently, not much was known Ma'ru. Turns out, the Ma'ru'fo, a people with tail fins instead of feet and gills as extra lungs, originated there. The meaning of the name, "Ma'ru'fo," is their ancient term for "Moon Beam."
Just like most real sisters, Earth and Erbede have many similarities and a special relationship as far as planets are concerned.
For one, they had no choice in the matter. They're connected, so connected they shall always be, and there's nothing anyone can do about it.
Earth and Erbede share not only their constellations and orbit around the sun, but also plants and wildlife.
