When Brokenstar attacks the ThunderClan camp, he ends up in a fight with Yellowfang. Yellowfang severely scratches Brokenstar, which renders him sightless and therefore helpless and at ThunderClan’s mercy. Brokenstar’s loss of sight symbolizes secrets and deception, reflecting how many characters in the novel are unable or unwilling to see the truth. For example, when Fireheart tells Bluestar that he suspects that Tigerclaw is dangerous and disloyal, Bluestar tells him that he’s mistaken about these concerns. Nonetheless, Tigerclaw continues to exhibit sinister tendencies. Another example is Graystripe’s insistence that his relationship with Silverstream won’t have consequences until he sees the truth during the battle with RiverClan warriors. Even Fireheart, to some extent, deludes himself, thinking that he can keep his visits with Princess a secret.

While Brokenstar’s vision loss symbolizes how characters sometimes fail to see the truth about their own actions and motivations, it also reflects the vulnerability of being unable to know the future. The cats face various threats, including war, disease, and famine: While they strive to make the best decisions they can, they don’t know what lies ahead. Individuals who seem trustworthy may turn out to pose a danger.
