Major Afendra is known for writing the unofficial guide titled “Major Afendra’s Guide to the Riders Quadrant (Unauthorized Edition)”, referenced throughout the Empyrean Series, particularly in Iron Flame and Fourth Wing. This guide is known for its candid and often harsh observations about life in the Riders Quadrant. It contains sharp insights, warnings, and advice regarding cadet life, combat skills, signets, and political realities within Basgiath College and the Kingdom of Navarre.

Though Major Afendra is not a directly active character within the main plotline, their presence is strongly felt through these pointed observations, which regularly preface or conclude key chapters, providing context, warnings, or foreshadowing crucial plot points.

In essence, Major Afendra serves as a voice of experience, often cynical and critical, aimed at helping cadets survive and understand the ruthless environment of their training and service.
