Extinction Beast
About
The end of an age given flesh - a predator so vast and unkillable that legend names it the thing that closed the door on the dinosaurs' world. Where it walks, ecosystems collapse, and it eats until there is nothing left. It appears perhaps once in an age, drawn up from some deep and lightless place, and the land it crosses takes generations to recover - scholars argue whether it is a beast, an omen, or a punishment, but the few who saw it and lived agree only that it was still hungry when it left.
