The Fflict, a fictional society in John Scalzi's "The End of All Things," has a unique understanding of gender, recognizing five distinct categories: male, female, zhial, yal, and neuter. This classification reflects a broader and more inclusive view of gender identity compared to traditional binary systems. Each gender has its own terms and pronouns, showing the importance of respectful acknowledgment of individuals' identities.

Aul is identified as zhial and prefers the use of zie pronouns, highlighting the significance of personal choice in pronouns. The text emphasizes empathy and understanding toward those whose experiences differ from traditional norms, illustrating the importance of using correct pronouns as a way to honor one's identity and experiences. This perspective invites readers to consider the complexities of gender and the importance of inclusivity.
