Long ago there was a mother with three daughters. The mother's name was Selena and her daughters were from youngest to oldest, Luna, Terra, and Gaea. The three daughters followed their mother everywhere. Of the three they were all granted the power to make one mortal race however they pleased. Gaea made the Humans, small adaptable, and very intelligent creatures that spread quickly and could advance their technology even quicker, though their ability with magic wasn't always the greatest. Terra made the Terrans though she didn't want much in terms of a mortal race she made the Terrans very resistant and even more adaptable to the environment than humans. And finally, Luna chose not to make a humanoid race and made beast-folk, a race of animals with the complete intelligence of humans and resistances to the environment they were born in. Their mother, Selena, made a planet for the races to live on named Selenus, and at first, everything was ok. The humans settled in areas where they made citadels and kingdoms and used their land well while the Terrans settled a bit more in the outskirts and due to their adaptive nature began to take on other forms, such as orks, minotaurs, centaurs, demonfolk, and even the first drakenblood. And the Beastfolk lived in the between of the two not far into the outskirts but close enough to have relations with the human and non-human races. Yes, everything was working out fine until the humans decided they wanted to spread their domain and spread their way of thinking and technology. At first, it was just negotiations with the Beastfolk for land then it was sneaking land from them then finally they fought for the land taking every piece and acre from the beastfolk driving them further away and into the territory of the Terran's descendants, known as the Inhumans, then an all-out war began some races of Inhuman's took the human's sides wanting power and technology and other fought against them including the beastfolk and Terrans. Soon Luna, Terra, and Gaea fought as well and despite all attempts from their mother to calm them down, nothing worked. It had gotten to the point that they chose champions and had them fight to the death for as long as they lived and if they died they would be reincarnated. It was an endless battle and Selena had just about had enough. It wasn't until the humans disgraced their creators Terra and Luna and made a weapon to destroy the foreign Goddesses. Selena stepped in and told the three to stop their fighting when the weapon malfunctioned and exploded. The force of the explosion was so powerful it tore off a section of Selenus and the beam from the machine's turret struck Terra tearing a large section of her face and arm off. Selena was infuriated, one of her beautiful children were harmed and because of another one of her children's creation, she had enough. Because the source of the machine's power was magic, humans were stripped of their ability to manipulate, and use mana, thus stripped of their ability to use magic. Gaea pleaded with her mother saying it was naught but an accident but she wouldn't listen, she used the pieces of Selenus that had been blown off and sealed Gaea inside of it, she then threw all forces that joined the human's side onto the new planet and threw it to the outer reaches of the galaxy. Selena knew that Terra would die if she didn't do anything so she used her powers to seal her inside a small planet as well and Luna decided to do the same, the two new satellites were set to orbit Selenus and Selena rested deep within Selenus to be awakened far into the future if the need ever arose.
Meanwhile, on the outer reaches of the galaxy, the planet which would soon be known as Earth was settling into its new solar system as the being within it let out all of her rage transforming all the surplus of mana to coalesce into beasts that ravaged the land
