The powerful, learned woman is a figure of fear in the works of Williams, seen as transgressing her proper role. In Lewis, legitimate authority figures are male, illegitimate ones are female, and gender roles are strictly demarcated. Tolkien, however, not only creates powerful and heroic women, but also suggests that the combination of authority and femininity can be particularly potent and talismanic.
