Patricus was captured as a young boy by High King Niall of Eriu land in one of his pirate raids of Roman Britain. The young boy became slave to a druid master and then was freed after seven years returning to Britain to finish studying to become a priest in the church. Then one night, Patricus had a dream where he felt called by God to return to Eriu land and spread his Christian faith and religion among the pagans. When he arrives on Eriu land, he comes face to face with the ruling sons of Niall, druids, and witches that he battles in his attempts to evangelize the emerald isle. An unlikely hero named Dovfield arises to assist the priest in his efforts at facing the ruling pagans of the old, Eriu ways. But, Dovsfield has secrets that he himself doesn't yet know. Secrets that unfold as the forest spirits guide him to his destiny to stand and fight against the tyrants that rule the land; a battle that unleashes the rise of Christianity in Eriu.
