Eclipse: The Lost Book of Ascension

What happens if after the winter solstice, the days keep getting shorter? And shorter? Until there is an eternal night? What happens as the darkness grows? And the creatures of dusk take control of the Mountain? And the quest for the third Book is the only hope? The Mountain is in its death throes as the Nazir send their wraiths to finish what the dusk-rats and grale had begun. Soon there will be no daylight to protect the Maelir and Faemir, and with each twilight there are fewer places to hide. Will the Mountain finally collapse under its own instability or will Atreu and Verlinden's descent find the words of salvation in the Lost Book of Ascension?
