Does this seem like a strange image to include in a sci-fi story? Hm. . . maybe it is partly an excuse for a good image of St. Michael, but then again perhaps not! I won’t spoil why he’s in Shards of Crystal, so you’ll have to read the book to find out.
This depiction of St. Michael is inspired by the statue found crowning the Castel Sant’Angelo in Rome, where, according to tradition, after many prayers by the people, St. Michael appeared and put an end to the plague ravaging the city at the time - hence why the original statue is depicted sheathing his sword.
