The Raavan myth on how the races and lands were divided.
Many millennia ago, the elves, dragons, mountain children, and the little ones lived together peacefully in one land. The elves in the forests, the dragons in the grasslands, the mountain children in the highest peaks and the little ones in the hills. Each race kept to itself and each race grew in number and variety. The dragons were the first to split, those with chromatic scales turning against their metallic brethren. But the dragons had great wings and flew to opposite corners of the land. The little ones were the next to split, the crafty gnomes disapproving of their simpler Halfling cousins. But the littles ones had many hills and established separate homesteads. And the elves told themselves that they would not fight, they would not split, for there was only one forest for all of them. And then the mountain children split, and the short sturdy dwarves exiled their larger blood-thirsty cousins from the mountains. The orcs moved into the forest. The elves were the fourth to split, some wanting to fight against the invaders and some wanting to maintain their carefully crafted peace. But they would not fight each other. So, for one last time, the elves came together and together they asked the land to solve their dispute. The land was the last to split, dividing the dwarves and dragons and halflings from the orcs and gnomes. And the elves were split from each other, some to live peacefully and some to fight for what was right.
