Here is the beginning of a legend. Long before Camelot rose, a hundred years before the myth of King Arthur was half-formed, at the start of the Red Century, the world was slipping into a Dark Age… It is AD 367. In a frozen forest beyond Hadrian’s Wall, six scouts of the Roman army are found murdered. For Lucanus, known as the Wolf and leader of elite unit called the Arcani, this chilling ritual killing is a sign of a greater threat. But to the Wolf the far north is a foreign land, a place where daemons and witches and the old gods live on. Only when the child of a friend is snatched will he venture alone into this treacherous world - a territory ruled over by a barbarian horde - in order to bring the boy back home. What he finds there beyond the wall will echo down the years. A secret game with hidden factions is unfolding in the shadows: cabals from the edge of Empire to the eternal city of Rome itself, from the great pagan monument of Stonehenge to the warrior kingdoms of Gaul will go to any length to find and possess what is believed to be a source of great power, signified by the mark of the Dragon. A soldier and a thief, a cut-throat, courtesan and a druid, even the Emperor Valentinian himself - each of these has a part to play in the beginnings of this legend…the rise of the House of Pendragon.
