On the mist-shrouded Isle of Hibernia, now known as Ireland, 26 years have passed since the murder of the high king, Fiacha Finnolach. The usurper Elim of Ulster’s promises of peace and prosperity have come to naught, as drought and famine afflict the land. Across the Irish Sea, the Roman Governor of Britannia, Julius Agricola, is met with an intriguing proposition. Fiacha’s son, Tuathal Techtmar, born when his pregnant mother fled into exile, has grown to manhood. He seeks the aid of Rome in avenging his father and becoming High King of Hibernia.

The year is 104 A.D. Two years have passed since King Decebalus knelt in submission to Emperor Trajan. The recent war between Rome and Dacia was brutal and costly for both sides. The graves of many thousands lie between the River Danube and the gates of Sarmizegetusa.

In the year A.D. 9, three Roman Legions under Quintilius Varus were betrayed by the Germanic war chief, Arminius, and destroyed in the forest known as Teutoburger Wald. Six years later Rome is finally ready to unleash her vengeance on the barbarians. The Emperor Tiberius has sent his adopted son, Germanicus Caesar, into Germania with an army of forty-thousand legionaries. The come not on a mission of conquest, but one of annihilation. With them is a young legionary named Artorius.

The throne of England is slipping from King Henry’s grasp. His only son has drowned in the English Channel, and the predators are gathering ready to devour both England and Normandy. When the last of King Harold’s housecarls returns to England to die, he brings with him a reluctant hero who will save the kingdom. Alfraed, son of Ridley, is the first of a new breed; he is an English knight.

Duty bound to save the Empire from falling further under a tyrannical usurper, Cursor resolves to unravel the conspiracy and bring the perpetrators to justice. Aiding him is an old friend; a retired Master Centurion named Gaius Calvinus. Regrettably, they know that if successful, Tiberius' retribution will be swift and brutal, sparing neither the innocent nor the guilty. This leaves only two dark paths for Cursor and Calvinus; either allow the pending reign of terror under a ruthless usurper, or unleash the unholy vengeance of an emperor betrayed.
