Ryugu

**Ryugu** is the great dragon sea god, a primordial dragon descended directly from Circunus and that played an integral part in both the Ethyria Project and the containment of The Darkness, and the creation of the mermaids and Atlantis.

## Appearance and Personality

Ryugu appears as a sort of intermediate between a dragon and mermaid form in the form of a "sea serpent". Ryugu's body is much more slender and streamlined compared to that of other dragons, but he is still much larger than any mermaid. The more streamlined and serpentlike appearance are adaptations to the water environment given they help him swim faster. Ryugu also lacks large wings because those aren't needed when you are primarily swimming through water rather than flying through air or space.

Ryugu's personality is not much known in the present, but it is known that he was a very fair dragon who sought to correct injustice and suppress darkness, even at the cost of his own life.

## History

### Beginnings

Ryugu was born during the lifetime of Circunus around 4.75 billion years ago, and was birthed directly from Circunus. Not much is known about Ryugu's time in Circunus' star system, except that he was entrusted to be one of the guardians of the Star System. He was often seen as the second main child of Circunus along with Madra. the mother dragon, and it was known that both were upset when Circunus decided that when Pendora's Box was forged, it would be passed to a lower level dragon.

When 4.7 billion years ago Circunus went supernova, Ryugu and all the other major dragons went into stasis, as while he was an independent being, his essence still depended heavily on Circunus' presence. After the Solar System formed from Circunus' essence and ashes, Ryugu and the others arrived and re-activated, as the essence was now once again contained in a celestial form, this time inside the sun and planets of our solar system.

### Dragon Sea God

Ryugu settled on Earth around 4 billion years ago in the Oceans and began to strongly associate with the element of Water, a key component of the Earth Celestial. His resonance with this celestial altered his form to be more in line with the celestial, converting it into the familiar sea serpent shape that Ryugu is famous for having. It also enabled him to gain immense power over the Earth's oceans, almost full and complete power over them. This earned him the title of the Dragon Sea God.

As Dragon Sea God, Ryugu watched over the Earth's oceans and were in charge of making sure the nascent life on Earth, which had just developed from protocells, was able to successfully evolve. During this time, Ryugu had a son, Merphis, and many grandchildren and great-grandchildren through Merphis, the mermaids. To set up a home for his descendants, Ryugu and them created a vast underwater city named Atlantis. While Atlantis was initially a trading and cultural hub for dragons to visit and mingle from all over the solar system, after a few millennia the rising mermaid populations displaced the dragons and the city became entirely a mermaid city.

### Darkness and Ethyria Project

However, as Ryugu monitored the Earth, he felt unease and eventually realized there was a rapidly growing darkness within the Earth that had been incubating for 700 million years and was ready to emerge. This darkness, The Darkness, would spell the end of all life not just on Earth, but possibly everywhere. To stop the Darkness, Ryugu called out to God Himself, who had been watching Earth as well. God resolved to stop the darkness, but as Earth had formed from the same material He had, He was unable to fully control the darkness due to that entanglement.

As such, God needed a foreign spirit of light who could assist. Ryugu, knowing he would need to be sacrificed to this end, volunteered anyways. God used Ryugu's power to cast a powerful magic spell to contain the darkness which came to be known as The Ethyrium, a ball of both light and dark, with the light from God's spell and the dark from the Darkness which was now sealed inside. Ryugu's legacy would continue on through the Ethyrium, which was made from him and sustained thanks to the Ethyria Project, and from the mermaid line.

## Powers and Abilities

Ryugu, as a primordial dragon and main child of Circunus himself, was one of the most powerful beings in the Solar System, potentially and likely exceeding God Himself in power. He possessed enough light energy to contain the darkness before it got too powerful when he became the Ethyrium, no easy feat and one that has to be renewed by God's own children every reincarnation cycle of theirs.

Dragon physical characteristics: Ryugu is inorganic and is a sentient collection of raw stellar material with a high density of Immaterial Essence, essentially being a being of pure energy. He can survive in the vacuum of space, does not need to eat, and is much stronger and durable than an organic lifeform. Ryugu was also able to survive after his father's supernova and remain in stasis until arriving in the newly formed solar system over a hundred million years later.

Aquakinesis: As a dragon who took on and essentially embodied the element of Water, Ryugu had unlimited control over all the Earth's oceans and water.

Flight and Swim: As the embodiment of the Earth's oceans, Ryugu could travel anywhere in the world's oceans almost in an instant. Ryugu is also capable of sprouting his wings once again when needed in order to travel space at large fractions of the speed of light.

Pure Power: Ryugu possessed an enormous amount of pureness power, which enables him to contain the Darkness within himself as the Ethyrium.
