Since time immemorial, the cinder spires have provided shelter for humanity. But the ancient power that once upon a time sank the world into a shroud of mists and filled it with monstrous and fantastic creatures has returned. Asleep for ten thousand years, the Ancient Enemy has awoken, and those great powers which once stayed the Enemy's hand are all but gone from the world. In the end, it is the loyalty and courage of a single airship's crew which will determine whether humanity will arise from its ashes or vanish forever.
