After the storm 5000 years ago earth underwent a massive change uprooting all the human civilization. Few who survived couldn't recall what they faced during the storm. Almost all traces of life had been wiped out from the planet.
From then on Earth didn't remain the same. A strange sort of energy was perceivable throughout the earth bringing with it countless changes. Earth started evolving and along with it the inhabitants that were still alive also started to evolve.
This led to a great struggle for existence among the inhabitants of the planet and led to a massive war. Humans who didn't evolve became the weakest memebers in the ecosystem and were dragged at the bottom of the food pyramid.
The creatures once humans hunted became hunters. They became more intelligent, more cunning and more dangerous. Humans who were left a handful went into huding.
Six major tribes flourished in the wake of this development. Roc, Tiger, Draco, Elves, Qilins and the Nymph. Tigers were the fiercest of the six and were proficient in wielding the power of fire. They were the biggest perpetuators of the massive genocide that occurred after the storm. Fortunately, before they could wipe out most of the creatures from the face of Earth the Dracos appeared who confronted the tigers with their control of earth element.
Similarly other tribes also were undergoing massive changes.
The oceans underwent the most significant change and not much is known about it. It is only known that the periphery of it ruled by nymphs and its branches runs throughout the single continent.
The elves were the tribe that hated war. They gained the power of nature and learned to communicate with the plants and lived in narmony with the nature of the continet.
And among the six two hagemons contested for the supremacy.
Rocs and the Qilins.
Rocs who wielded the power of wind became the master of sky and surveillance. And the Qilijs with thier thunder became the overload of land.
Qilijss ruled the land for 4000 years and on the dawn of the fifth millennia a seventh tribe emerged from the shadows "humans". The old overlords. Perhaps the humans gor the most simple and most unique transformation of all the major tribes. It wasn't actually a transformation but a discovery. Humans discovered a way to wield magic.
