Explanation: The quote reflects the mythic and enduring nature of King Arthur's legend. Despite his apparent death, there is a widespread belief in England that Arthur is not truly dead but has been transported to another realm by the will of Jesus Christ. This belief holds that Arthur will return in the future to achieve a great and holy purpose, specifically to reclaim the holy cross. This idea is part of the broader Arthurian mythology that portrays Arthur as a messianic figure who will come back to save his people in their time of need. It underscores the hope and longing for a noble and just leader who embodies the ideals of chivalry and righteousness, symbolizing the perpetual human desire for a savior in times of despair.
