Prologue- The Prophecy
Centuries ago two ancient magics combined to create a spell, or curse of sorts. This curse came to be known The Curse of the Children of Fire and Ice.
The curse was an agreement between the elements of Fire and Ice and, mediated by the elements of Earth and Air. The constant bickering amid the two was becoming hazardous to the inhabitants of the earth.
Each element argued that they were meant to battle the other, each protecting the earth and all those who dwelled upon it form the other's destructive forces.
Therefore, because neither would accept the reality that they were meant to coexist, each one balancing the other, Earth and Air decided to prove to them that they could work together and complement each other.
So, it was determined that Fire and Ice would each produce a child made in it's own likeness with all of its blessings and, if the children could not see past their differences and learn to love, accept, and respect each other then the elements of Fire and Ice could obviously do the same.
Fire and Ice accepted this test and agreed not to interfere with their or influence their children in any way. Both resolved to abstain from quarreling until the outcome had been learned and the verdict given.
However, each still had their conditions; the children had to be complete opposites and would be taught to hate one another since birth, just as their elemental counterparts had been.
Only if they could overcome all these obstacles to come together as one would both Fire and Ice agree that they could indeed coexist with each other and they would be forced to at least attempt to learn to love, accept, and respect each other as well.
Air was delighted and quite assured that victory would be theirs. While Earth, on the other hand, was quite worried because the gravity of the situation was much larger than any of the other elements had come to realize.
If the experiment should fail, the consequences would not only include Air's wounded pride, but also, the eventual end of the mortal race.
For if the experiment failed and, the two began to fight again. Then the world would enter a state of chaos, with a constant war between the two elements where all life on earth would be plagued with wild uncontrollable fires, massive floods, never ending snow, scorching heat, hail as big as an infant's head, and tsunamis until the inevitable entire elimination of planet earth… but no pressure.
