Aderyna

**Aderyna** (Terra Avium) is a planet with the Shatterverse and is the third planet within the Avian System. Aderyna has two moons: Telekanti and Nilikanti, and is home to one of the most abundant and lively flora and fauna. Its main sapient species are avians - humanoid bird creatures of all shapes and sizes. Aderyna is the origin of the magic systems: Domain Synergy and Eildic Glyphology

## Geography & Ecology

The Aderynan surface features forests, mountains, volcanoes, plains (savanna), and oceans. Similarly to Earth, the forests of Aderyna contain a wide diversity of flora and fauna, with giant forests and trees suitable for building cities upon its branches. The planet's gravity is also lighter, featuring more oxygen within its atmosphere thus the appearance of many large lifeforms.

### Avian

Compared to the Shatterverse, the most unique race on Aderyna appears to be the avians - bird-like hexapodal humanoid creatures with a pair of arms, wings and legs. They're intelligent creatures and, though their history proved them to be territorial, has grown to be more accompanying of other avian races. There are many species of avians and are spread across the planet - each with different religions and cultures and way of life. Their diet mainly consist of nuts, fruits, insects, and some mammals.

Their cities are usually designed to avoid predators down below, utilizing height and flight. In towns or cities where forests are abundant, their homes are often high up in the leaves. Some other cities by the shore tend to be built on rock cliffs or further inland. Avians are the only sapient mortal race on Aderyna.

Avians also often cooperate to defend themselves against outside forces and different clans. They have also learned to farm giant insect species and harvest nectars from different plants.

They are capable of manipulating Domain Synergy, using eildic glyphology, and bonding with ethos. Avians are also capable of bonding with an Elemental, but there hasn't been any case of such things. Elementals are generally regarded as too powerful to be wield by mortals.

### Ethos

Ethos are mystical spirit-like creatures made from fragments of Elementals. They are very attuned to nature, often seen as forces of nature themselves. Most of them are non-sapient, but sapient ethos (great ethos) are at least a century old. Ethos function similarly to the mechanics of Elementals. An ethos never truly dies, but instead loses their sapience and awareness, making their mind undergo a "input" state - similarly to that of a computer.

Ethos were the first users of Domainer Synergy - the manipulation of certain elements. They speak in the language of drawn sigils and symbols called glyphs - which is also their method of casting spells. An ethos can only manipulate one element, but generally don't gain exhaustion from overusing it. More powerful ethos have larger Reservoirs and more command of the regions around them.

An ethos can be bonded with a mortal being, turning the being into a Domainer and strengthening them both. A dead ethos can be attached to a being's soul, turning them into Domainers also but with limited powers. A fused ethos soul can be genetically passed down - their powers splitting and duplicating as they're passed onto the next generation. Curently, no Domainers have bonded with a living ethos, and Domainers function via their souls attached to "dead" ethos.

Great ethos, upon "death" and without a soul to attach to, will accumulate their powers in the physical realm and fossilizing into eilds. Eilds are gemstoens that can store and channel power, commanded by the language of eildic glyphology spoken by ethos. If a regular ethos "dies" without a soul to attach to, their soul essence will pass onto the nearest object or being - possibly granting it sentience if culminated enough essence.

Great ethos have centralized societies in the spirit realm and are generally very territorial. Ethos appear in the material realm through things respective to their element - such as plants, animals rocks, fish life, etc. Powerful ethos can have permanent 'homes' inside certain things they possess. They interact to other living material beings through the cognitive realm. But as of current events, ethos rarely show themselves in the material realm due to a genocidal event caused by Qwui. Ethos don't like the idea of their dead attached to a soul and only capable of listening.

### Flora & Fauna

Aderyna's atmosphere has a lot of oxygen coupled with a lighter gravity, enabling the lifeforms to become very large.

Aderyna features an incredibly diverse and grand varieties of nature. Forests cover most of the land areas - taking up to nearly 50%. Aderyna's climate is harsher in some places, while lusher in other places - like Earth taken to extreme. Plants and fungi become gigantic in sizes

In the tropical forest areas, rainfall is abundant and the ecosystem diverse. In areas such as Rajamerak, there are forests of giant trees able to hold up cities and towns. Rainmoss is a common moss that is used as a source of synergy intake as well as a defense against predators lurking in the tropicals. Some fungi species - such as the Pearlcap and Sun Mane - and have an internet-like network, though are limited to only several forests across Aderyna.

Some other prominent forests include Everfall - a boreal forest unique for its constant orange leaves all year long. Various other terrains include deserts (Erimosk, Sharadun, Thenakii), praries (Avokii, Gold Fields, Three Folks Grasslands). mountains (the Sierra Whispers, the Canary Peaks, the Skytops), jungles, swamps, tundras, etc.

Bugs, such as dragonflies and centipede, resemble that of Earth's prehistoric giants but larger. Their average size, depending on the species, range from 2-5 meters in size - similar to that of the Quorls from the world of Malazan. Invertebrates generally dwell on land and on trees. Some species of invertebrates - such as Scorchblights and Lurchworms - are considered predators. Many civilizations have created ways to defend themselves against creatures like these.

Mammals on Aderyna also seem to be gigantic and enormous. Woodrats, creatures averaging 1-2 meters long, are farmed by avians. Some other mammals include species of the Eutriconodonta and Monotremata order, as well as several takes on modern animals of Earth today. Curiously, there are no non-humanoid birds, and there are no humans (there are still primates on Aderyna, however).

Various other animals are also present, including reptiles - notably the Jungle Viper - and many aquatic creatures of leviathan size.

## History & Mythology

### Pre-Migration

The Avian System was created by an unknown deity or group of deities, and inhabited by a race of people long lost and forgotten in the history of time. A large-scale war happened, which wiped out almost the entirety of the creatures, gods, and entities on the Avian System. This led to the abandonment of Solra, losing its magical powers - as well as the abandonment of Tele and Nili. The aftermath of this war led to a cataclysmic event, which sent shockwaves through out the entire system. After some time, however, entropy collided with each other viciously to form sentient Elementals.

The Old Spirits of Aderyna are rumored to have spoken of the days before the Migration of Gods. Information about the world before then was very scarce and mostly forgotten. Through some research by Guild of the Farseekers, they've managed to pin point some crucial locations to determine the ancient history of Aderyna.

Traces of scattered, broken weapons are found on the planet Vicgathar - currently known to avians as Undirheim. It is theorized that before its repurposing into an underworld planet, it was once inhabited by an extinct race of people, or at least a large-scale war was mainly fought there - extending to the entire solar system. However, the planet is currently uninhabitable and unbreathable, making traveling there incredibly difficult alongside its chaotic and rare rifts. But there have been sightings of Old Spirits - the likes of Aderyna's - still dwelling there. Some other speculations point to Marquan - a dark planet within the same solar system containing cave-dwelling life forms. It is said the creatures existed before the Migration.

#### Reis Rithe

After the dust have settled, the magic was bundled and turned chaotic, forming incredibly powerful Elementals called An'Telats. Reis Rithe, meaning "Kings Roam" was an age when the An'Telats roamed Aderyna. An'Telats were representations of natural elements of earth. There were three An'Telat from the beginning: Sky, Earth, and Water.

During the Reis Rithe, terrains were reformed and recreated on Aderyna. And with it came the ethea, children of Elementals created to fight their wars. However, the lands were still unstable and destructive, with the Elementals raging wars with one another. This created the stark difference between terrains. Ethosian life were constantly destroyed and renewed. After some time, some ethea gained sentience from the culmination of magic, age, and other fused ethos. The ethos would eventually become a separate entity from the An'Telats, and some grew to despise the wars.

#### The Regeration

During the Reis Rithe, many uprisings happened between rebellious ethea and An'Telats - yet almost all of them failed. The most prominent one, however, was the Regeration - when ethea gained help from the Old Spirits in gathering and distilling the old magics.

Ethea mimicked magical shockwaves which, before Reis Rithe, was an entropic factor in the old world's desolation. The Regeration, however, killed a lot of ethea - fossilizing them into the natural regions where they infuse with certain gemstone minerals called eilds. But the aftermath of the rebellion sent out massive shockwaves off-world, signaling outside forces to the Avian system, as well as weakening the An'Telats enough for outside forces to interfere. This would eventually attract Theruee and the First Flight.

### Migration

The Migration is an incredibly important part in Aderyna's history and is the beginning of Terra Avium. Theruee, after escaping from his homeland's wars, gathered other gods from other planets. The First Flight was formed, led by the sun god Theruee and the moon goddess Qwui. The gods took on bird-like forms, migrating to find a new home and ending their journey in the Avian system. Theruee moved into Solra, fueling it with his own magic, while Qwui took charge of the moons and planets (except for Aderyna) - mainly Tele and Nili. But the other gods needed something to rule over as well.

The First Flight chose Aderyna as the place to create life. Thus, avians were born - shaped and molded from birds of other planets, yet obtaining a humanoid shape.

Some ethea and avians were able to bond with each other, creating powerful Domainers that could shift the elements to their will. The earth ethea suffered the most casualties, and from their deaths the gods rebirthed them into a different form: the forest ethos.

The First Flight sought atfer Aderyna's original inhabitants, wanting to ask around for information and to make a deal. The ethea warned the First Flight against peace-making with the An'Telats, but the First Flight proceeded. The Elementals weren't fond of this new force so they decided to destroy Aderyna, the First Flight, and any ethea rebelling against them. This started the Amatagan - the War of Commencement.

#### The Amatagan

The Elementals killed countless avians, ravaging genocide upon the race and greatly angering the gods. The Amatagan was a long and painful war, hurting both sides severely. During the Amatagan, the rebellious ethea offered help to the gods. From this, Theruee realized that Elementals can also be bonded like ethea, but they needed a way to silence the Elementals to avoid corruption from bonding. TTheruee also learned of the Old Spirits, thus begin seeking after them.

With help of the Old Spirits, Theruee culminated the old powers into a weapon, crafting the Sunrazor - a deadly and incredibly powerful weapon invested with Old magic and Theruee's sun magics. It was capable of cutting through anything except the spiritual form, and able to severe a Soul Link. Wounds made by a Sunrazor cannot be healed through mundane means, and is incredibly difficult to heal through magical means due to the burning solar essence. With the Sunrazor, he severely damaged the Elementals, turning the tables to his favors. Some powerful great ethea were granted their own divine-powered weapons, only bestowed unto the strongest of Domainers called Archaviators.

The Air An'Telat, Ha'Sithri, after some time grew accustomed and even liked the avians for their respect to flight. It also saw the unrelenting stubbornness of the other An'Telat. So Ha'Sithri decided to join the gods, betraying the others and aiding in the Amatagan. Ha'Sithri looked over the skies, scouting and striking those who opposes it in the war.

Eventually, the opposing An'Telats were cornered one by one and slain by the Sunrazor. The remaining An'Telats' Soul Link was severed, removing the physical, cognitive, and spiritual body away from each other. One by one, Theruee disembodied the slain Elementals' bodies and scattered their parts across Aderyna. The bodies melded with each other, creating a transition between terrains and geographical regions. The souls of Elementals, now considered "dead", underwent a listening state and bonded with the gods, granting them dominion over the elements.

Only Ha'Sithri didn't meet this fate, and was placed above the lands to watch over the avians and any troubles that would concern the gods. Opposing great ethos and the minds of Elementals needed somewhere to go, so the First Flight repurposed Vacgathar into Undirheim, then banished the oppositions to that planet. Many opposing mundane ethea died away, escaped, or went under new rule of allied great ethea. The gods continued to distribute powers amongst each other, finally dawning a new age for birdkind.

### Re Aure

For some time, clans and nomadic tribes were built. But due to the guidance of gods and the ability of flight, connection and trade quickly began. Geographical, astronomical, and cartographical technology developed. And not for long, the first avian city was built, naming itself Ar Pero - meaning "First Feather". This began Re Aure, meaning the Golden Age. Culture sprung abundantly. Trades were established. An avian life flourished across the continents and seas.

Arkhaism, the largest religion on Aderyna, was established. With it the tradition of singing the Dawn Chorus, and the beliefs in the three Domains and its deities. Ethosian culture had large influences on Arkhaism and avian life. With the bond, both avians and ethea grew stronger faster together. Several more cities are established, namely Eili Mar and Sol Virstre.

However, tensions began lurking in the gods' domain. Qwui, the original moon goddess, was devastated after Amatagan. She began hating Theruee and his power and the love avians had for him. She decided she wanted to reset it all and start all over. Many gods who were traumatized joined in her ranks. Qwui plotted behind Theruee's back. She was to unleash the old ethea and An'Telat back into Aderyna, but it required her to capture an artifact in Theruee's possession.

### The Sorelion War

#### The Attack on Ar Pero

The Sorelion War started when Qwui launched an attack against Ar Pero, wrecking devastion upon it. This caught Theruee's attention. The battle lasted seven days and night, and Ar Pero fell. Other cities and societies were alerted of this fairly quickly. War was declared. Soon enough, two sides were apparent: The Sun and Moon. Back then, these are two completely equal domains of power as Qwui was Theruee's half.

Both sides threw everything at each other. Ha'Sithri's powers were divided among Qwui and Theruee, so much so it couldn't join the war due to split consciousness.
