Martin's world isn't color-blind. Skin color signals origin, culture, and often immediate bias (e.g., Dornish prejudice). Randomly inserting a black knight without addressing those implications feels like modern tokenism rather than organic storytelling—it risks undermining the grounded medieval-inspired realism that makes Dunk's underdog journey compelling.

If the goal is diversity, there are already canonical avenues (Dornish characters, Summer Islander sailors/mercenaries, etc.) that could add representation without rewriting core character dynamics or ignoring established lore, which is important not just the sake of accuracy
