How does one kill a god?
The full might of Mad King Gwyn's unstoppable army of nightmares bears down on Autumn and the Fields of Reversal. Dwarves and elves alike scramble to find the means to defeat the unkillable.
As the royals and nobility of all courts prepare for the battle ahead, it is left to Aymon, Grisell, Arne and Brynhild to delve into the Spirit Realm and seek the answers they need from the very gods who have already failed to defeat Gwyn in the past.
What they find will unmake every aspect of Fae society - if they can survive the final confrontation with the Mad King himself.
