The King and the Sacred Relic

He was his teacher, his friend, the one who had stood before him like an impregnable wall, protecting him from boyhood into adulthood. Only after arriving in Jerusalem did he learn that the man was a wraith, stripped of his memories and soul. He had forgotten everything that came before, and slaughtered his loved ones for the enemy. He should have destroyed him outright, just as his mother had warned him to do. But how could he give up his ideals, or the person he was most devoted to?

A bizarre idea I jokingly tossed around with a friend: after the Lion died, the Fox turned him into a holy relic and put him to work for the Capet family. The main pairing is Louis IX x Richard I, with a little Fox/Lion and a Moon background.
