The similarly named Dragomirna Monastery is located in Suceava, Romania, though Bowen wonders if Bellairs found the name appropriate because of the dragon- echo.
Myers says the illustration of Dragomira was heavily influenced by Sergei Eisenstein's movie, Alexander Nevsky. "Prokofiev's cantata, from his score for the film, was a favorite of Bellairs and mine."
Marilyn Fitschen says she believes she saw a picture of a hand (or first) on a helmet somewhere [as inspiration] for Dragomira. "I may have been thinking of Don Quixote when I drew the figure on the horse. I do remember thinking of her troops as Valkyries (from Wagner's Ring Cycle). They were, of course, Norse.”
