It is recalled that in the 5th century, the Druid Merlin had helped the young Arthur to become king of angleterre. But Merlin, victim of the Morgan Fairy, had ended prisoner in the heart of a rock... Centuries later, in the middle of the age, Merlin was liberated. The men of An Mil no longer interested themselves in magic and everywhere the chapels of the Christians replace the ancient dolmens. The small people of the fairies are dying, the dragons have almost disappeared, Ireland is invaded by the priests. With the help of a few pints of beer and the young Gwyned, descendant of Galahad, to whom he entrusts the fabulous sword Excalibur, Merlin will seek to cut off the litter out of Ireland and to save a world of magic and enchantment gradually destroyed by the new beliefs. Adventures, humor and secularism, a new series to the amazing scenario served by the drawing of a newcomer: Eric Hubsch.
