Celtic Britain is on the brink of collapse, and the kingdomβs bloodiest days are upon it. For many years, the people of Britain have enjoyed peace and prosperity under the reign of King Arthur. But Arthur is now weakening with age, and the seeds of discontent are being sown.
Seeking to cleanse the land of Christian belief, dissenters need a symbol with which to legitimize their pagan claim and unite the malcontents. They seize upon the ancient Cup of Bishop Lucius of Glastonbury as a way of fragmenting Arthurβs hard-earned kingdom.
The ultimate threat to Arthurβs rule lies far closer to home: his own kin will betray him. Celt will slay Celt and the rivers will run with blood. Will all be lost, or can Arthur conquer the mounting forces before itβs too late?
