During the time where it was not numbered and where there were no continents, there were many Kingdoms. All Kingdoms were separated into three groups: The Humans Kingdom, which they have split into four small groups, ruled by different Queen's and King's.
Then, there are the Elven Kingdoms. Yes, Elves. Two Kingdoms, with different looks, skin tones, even eye color. You have the Dark Elves of the Dark Kingdom and the Sky Elves of the Light Kingdom. Both humans and Elves stretched themselves from each other.
In the Elven Kingdom, there were many small wars. So, the great King's of both sides set laws.
"Each tribe shall stay on their own side. Crossing the others side without permission will be an automatic tortured life for you." said the Sky Elf King.
"No Sky Elf and Dark Elf shall come to be together. If thee are to conceive a child with the opposite Elven side, it shall be killed and you will too, be tortured for life."
And so the rules went on, and on, and on. And each Elf from each Kingdom obeyed for sentries, until came along the next Elven Queen and King of each Kingdom. Princess Elora of the Sky Elves and Prince Voron of the Dark Elves.
