The End of Civilization as we Knew It; Saints on the One Side, Saxons on the Other

An Arthurian trilogy comprising nearly 1500 pages has come into my possession thanks to someone having an inkling of my tastes and generously hoping to satisfy them, I will be eternally grateful. Written by Bernard Cornwell as the 'Warlord Chronicles' (The Winter King', 'Enemy of God' and 'Excalibur), Arthur's story, recounted at the behest of Queen Igraine of Powys by Lord Derfel Cadarn, a war-lord turned monk; he fought with Arthur to hold the incoming Saxon tide that takes place in the final years of the 5th century A.D., whilst remnants of the Druidic religion live on mainly in the person of Merlin appealing to the Gods of Britain to fight back against the new eastern religions, brought to us through Roman rule before the legions left us to fight for ourselves, including Christian fanaticism, Mithraism and even the cult of Isis. Merlin's efforts fell short, Arthur had more success, better than Cnut, but in the long run, rightly or wrongly, the majority of us now take our moral lessons from the Hebraic Scriptures in English.
