The novel explores the intersections of cultures, particularly between the colonizing Homelanders and the native Hillfolk of Damar. McKinley approaches this theme with optimism and compassion, offering a vision of unity and mutual respect forged through individual relationships, shared values, and transformation. While this vision is also embedded within the limitations and contradictions of its time, the novel seeks to explore the nature of cultural tension and reconciliation. 

The early chapters of The Blue Sword make clear that the Homelanders are foreign occupiers in a land they do not understand. Istan is a distinctly British colonial outpost, complete with cultural superiority and administrative detachment. The Homelanders, including Sir Charles and his wife, Lady Amelia, live physically and culturally apart from the native Hillfolk, whom they regard with suspicion and a sense of exoticism. The wall around the Residency is a literal and symbolic divide between cultures, and Harry’s initial curiosity about the Hillfolk is framed as unusual for a Homelander. When Corlath arrives at the Residency to warn of a Northern invasion, the Homelanders dismiss his warnings and treat him as an irrational native, despite his authority and intelligence. As the two main sympathetic characters within the outpost, Harry and Jack, respond with greater openness, it becomes apparent that the novel offers a critique of imperial ignorance and arrogance.

Harry’s incorporation into Hillfolk culture, while initially framed as an outsider integrating into a foreign culture, is that of a person displaced from their cultural heritage rediscovering their roots. This narrative move sidesteps some of the thornier implications of a colonizer becoming a native hero by suggesting she was “always meant” to belong. Nevertheless, Harry’s increasing identification with the Hillfolk is portrayed as sincere. She trains hard under Mathin, endures the laprun trials, and earns her place as a Rider. These chapters emphasize discipline, loyalty, and honor—values that McKinley treats as universal rather than culturally specific.

The battle at the Gap serves as a culminating moment as Hillfolk and Homelanders fight side-by-side against the inhuman Northerners, a symbolic enemy that threatens both. The Northerners are never fully explained, which serves to unite the two peoples against a common enemy but also avoids interrogating the more complex realities of real-world colonization and conflict. In fantasy terms, however, the battle represents a hopeful moment where, through shared sacrifice, a new alliance is forged. Harry and Corlath marry, and she becomes queen, blending her dual heritage into a political and personal partnership. Jack is made a queen’s Rider, further solidifying the role of Homelanders who choose to serve Damar rather than rule it. Even Sir Charles, the embodiment of colonial governance, begins to support diplomacy with Damar, prompted by his changed perceptions following the actions of Harry and Jack.

The Blue Sword presents a vision of cultural bridging that is hopeful yet constrained by the genre and historical moment in which it was written. Published in 1982, during a period when fantasy was beginning to reckon with more inclusive narratives, McKinley’s novel stands out for centering a female protagonist who crosses cultural boundaries not to conquer but to serve and protect. The novel’s structure remains reliant on tropes that can reinforce colonial hierarchies, even as it seeks to challenge them; nevertheless, The Blue Sword is ultimately a story about building something new. McKinley does not suggest that the Homelanders should govern Damar, nor that the Hillfolk should adopt Outlander ways. Instead, she offers a third path: One where individuals from both cultures come together through respect, shared struggle, and affection.
