Following a spell gone wrong, ex-assassin fire witch Iefyr Sealash wakes from five years of contentment in the Haven Cove refuge to find his mind shattered and his family captured by High King Nylian's warlocks. As his memories collide with his present and his wife Benny is forced to undergo the Spellkeeper completion sequence, Iefyr is sent on a quest to find an ancient Spellkeeper who may only exist as a legend.

Iefyr's fragmented mind is only one adversary he must face. The price of failure is high. If he does not return the missing Spellkeeper to the capital city of Anthora, he will be declared a traitor and permanently separated from his spouses and children. The threats of the High King and the Moonlight Guardian are ever-present as Iefyr gathers his allies and follows them into one of the most dangerous places in Bacra—the deep labyrinth of the Underground.
