Methuselah

In the dawn of history, there was a greater civilization. Masters of the world. All of the known world was once ruled by a race known as the Endless. They built great cities, mastered the elements, and even delved into the creation of other species. But, as with all empires, they grow too big to hold themselves together. With civil war and rebellion, the society of the Endless crumbled, and their people vanished.   Millennia later, the world is in a state of relative peace. The Chromatic Dragons have been hunted into obscurity, the Metallic Dragons hold domain over a proud serving people, the forests teem with wonders both mundane and magical. No more are there those in slavery forced to compete in blood sport. No more are the folk of the world predated upon by larger beasts, and if they are, they can stand with a solid fighting chance. Sure, the dragonslayers still hunt the dragons, and the fey trick the humans, and man will be led astray by greed and pride, but the world will survive these quarrels.   But there is a trouble brewing. A new creature has been crawling from the southern jungles. One that hungers. And will consume all. Scouting parties have revealed the jungle is being rapidly deforested, the ferns derooted, even the grass plucked. A desert remains where resplendent canopies once shaded, leaving behind sand and the metal fortresses of the Cravers. This, the world would not survive. Left unchecked or unsated, their empire will grow into the other kingdoms, and consume all.
