The Dragon Prophecy was the subject of a major storyline within "Generation Two" of our universe.
Since time immemorial, the three celestial Dragons had stood watch as the galaxy's most powerful protectors. Unfortunately for the universe, power corrupts, and after millennia of working alongside each other to maintain peace and order, the three Dragons began to fight one another.
One one side of the fight, Daniel and Eli Almis, who believed themselves to be so powerful that they should rule the galaxy with everyone worshipping them as Gods rather than the three of them serving to help the galaxy. With this mindset, the two Dragons began a galactic conquest, dominating anything and everything in their path.
On the other side of the battle, was Ven Almis. Ven had remained dedicated to protecting the galaxy and always would, despite the darker choices of his brothers. Unfortunately, he was outnumbered and outmatched and chose to go into exile deep within unknown space, hoping for a miracle to come along one day to put things right. Luckily, that day would eventually come.
The Universe had grown tired of such powerful and unstoppable beings laying waste to the galaxy, so a prophecy was enacted. One that told of the birth of a celestial dragon so powerful and dedicated that it would be able to stand against the might of the other three dragons combined and still defeat them if it ever came to that. This prophecy needed to be acted upon immediately however or else the galaxy might well have been destroyed. In a time of great need, the Rift of the galaxy emerged, making itself known to the galaxy by slightly altering timelines to artificially insert the fourth dragon into existence. This being would eventually come to be known as Bethany Almis.
For many years, the child of the Rift would live a somewhat normal life on Earth until the day that she would be found and trained by her older brother Ven. He would help her realize and reach her maximum potential until one day, she would be powerful enough to fulfill the prophecy. Eventually she did. With the help of her older brother and the betrayal of Dan by Eli, the fourth dragon managed to set things right in the galaxy ending the conflict once and for all as balance returned to the universe. After the prophecy was complete, the child of the Rift disappeared, making her way to the Rift to become its eventual Queen and one of the most powerful, yet reclusive beings in the galaxy.
