The West burned; the East flourished. Just as the gods had made them.
As the years, decades, and centuries crept on, the elves of the East would establish vast civilizations, netting the continents with roadways and dotting them with cities. The West, meanwhile, emptied, with those few denizens left becoming fiery demons and vicious scavengers. From time to time, incursions would be made; East to West to seek out artifacts of ancient times, West to East to find food and resources that were depleted in the dead ground of their home.
The Easterners would develop militaries, first to protect themselves from these invaders, then to strike back at them before they could even try to invade. But they had only ever fought the scavengers; as they fought their way across the Western lands, they encountered stronger foes, animals bent to their environment to be as deadly as possible, and finally, the burning soldiers of the Fearful Knight.
And so, under blood-red skies, the world came to a heated night. The Knight struck at these unscorched masses, and the jungles burned. The druids found their magics useless when faced with the ashes that the red army left.
By the end, only two cities remained standing on the Eastern hemisphere: Adjilia and Tamblèn, the temple-cities of the Seers and Dragons. They held the dread armies back - Tamblèn with their powerful and new magics, Adjilia with their advanced sciences and strategies.
Then, when the last hopes of elfkind seemed to be fading away, aid arrived from an unexpected source. From a city of old, long held to be mere legend, came the Army of the City of the Orange Light. Hidden from the blazing legions by the residual power of their god and guardian, they protected themselves from the death of the West, then came to save the East. Facing an army undepleted, the warriors of the Fearful Knight were forced into retreat, before being broken with the killing of the Fearful Knight himself.
Three cities. A scorched world. Two peoples stripped of their innocence, and one that lost it long ago. But they remembered their gods from the days of old, and they were prepared to face their future anew.
