The Dark Decade

Geological / environmental event

ten years of darkened sky's, no sunlight, it even appeared that the moon and sun had completely vanished.  the World grew cold and ash fell from the sky.  Much of the life on the planet was snuffed out, crops were unable to grow, livestock unable to graze.   Many city states vanished, and even the mighty Crastion Empire was unable to to survive, and fell to the worlds turmoil.
