However one day, Humans - who are not born naturally with a primal arcanum of magic(an innate understanding of whichever source) - grew tired of not being able to do magic and uncovered a seventh source, dark magic.
It requires that humans kill a magical creature in order to be performed. Humans refuse to stop practicing it, which pisses off the elves and dragons so much that they Trail Of Tears' the humans to the west side of the continent and divide it in two with a lava river.
The King of the Dragons guarded the border for many years. One day, in the winter before the show begins, humans from one of the kingdoms used dark magic to kill the King of the Dragons, as well as allegedly destroy his only egg, the Dragon Prince. The Dragon Queen hires a group of Moonshadow elves to assassinate the human king responsible, along with his son. Thus, the events of the show are set into motion.
