Vael stole magic from the gods for her people and put an end to centuries of unrest. Now magic is gone, and the battle for the Witchlands’ soul begins anew.

After a millennium of prosperity and magic, one catastrophic night undoes the realm of Yvaelen. Magic has fallen, and prayers to Vael the Giver go unanswered.

In Spellfall’s wake, the Restorationists seek to replace lost magic with experimental technology, causing rifts between the old ways and new. King Thealys Vorrine is trying her best to bridge the gap between the two eras. But when a charismatic priest of the Faith rises in the ranks wielding an offer of bloody salvation, Thealys finds her allies disappearing one by one.

Across the realm, a con artist, a lost knight, a priestess, and a bandit queen fight fate and society to find a path forward for themselves, while the shattered voice of a god cries out from the mouth of a monster.The dark betrayal behind Spellfall, and the very fabric of Yvaelen’s faith, will be hidden no longer. What began with a thief’s touch will end with a reckoning. And deliverance for some may be a waking nightmare for others.
