The use of magical elements in "The Chivalry" suggests that the main idea or theme of the story is about the importance of personal integrity and staying true to one's values, even in the face of temptation or pressure to do otherwise. Mrs. Whitaker encounters several magical items that could potentially give her power or wealth, but she refuses most of them because she recognizes that they come at a cost to her moral principles. For example, she turns down the magical ring that could make her wealthy because she knows it was stolen and she doesn't want to benefit from ill-gotten gains. Similarly, she refuses the magical potion that could make her irresistible to men because she values genuine human connection over superficial attraction.
By refusing these magical items, Mrs. Whitaker demonstrates her commitment to her own moral code and integrity. This suggests that the story is advocating for the importance of staying true to one's values, even in difficult or tempting situations. It also suggests that the pursuit of power or wealth at any cost is ultimately unsatisfying and can come with serious consequences. Thus, the use of magical elements in "The Chivalry" serves to reinforce the story's main message about personal integrity and staying true to oneself.
