The Battle of Galen's Vale is over, but the war for the Empire's future has just begun. Concerned by rumors that the Magistratum's authority is waning, Sir Konrad Vonvalt returns to Sova to find the capital city gripped by intrigue and whispers of rebellion. In the Senate, patricians speak openly against the Emperor, while fanatics preach holy vengeance on the streets. Yet facing down these threats to the throne will have to wait, for the Emperor's grandson has been kidnapped - and Vonvalt is charged with rescuing the missing prince. His quest will lead him - and his allies Helena, Bressinger and Sir Radomir - to the southern frontier, where they will once again face the puritanical fury of Bartholomew Claver and his templar knights - and a dark power far more terrifying than they could have imagined.
