In the concluding installment of The Changeling Trilogy, the Great Battle between the Danaans, the forces of order, and the Fomors, the agents of chaos, is joined. In Tir na Si, the Danaan stronghold under Benbulben, Paul is initiated into the mysteries of Druidism in an effort to understand the nature of the Danaans' chief adversary, Balor, King of the Fomors. But the truth revealed to him is more terrible than his worst nightmare. Chant of Fire depicts both the conflict between the universal powers of order and destruction, and the internal conflict between reason and instinct, between pessimism and passion. It is an odyssey into the innermost recesses of the human spirit.
