The Golden Age of Man ended with the breaking of the world. Some surviving documents imply that humankind tried to destroy itself, while myth and legend claim that Jormungandr, the World Snake, rose out of the sea and poisoned the sky as the series of events know collectively as Ragnarok began to unfold around the Earth.
The truth is lost in time. The great Empires of Man are dust and twisted ruin. Strange magics flow through and across the surface of the World. Gateways open to strange dimensions. And Mankind stubbornly goes on.
