In "The Mark of Athena," Percy reflects on the challenges faced by demigods, feeling torn between the worlds of mortals and the divine. He understands that the rivalry between the groups of demigods stems from the tension that exists between their respective heritages. However, he holds onto the hope that unity might be possible, not only for himself but for all who share this dual life. He believes that finding common ground could provide a sense of belonging that transcends their fragmented identities.

Percy recognizes that being a demigod means navigating the complexities of feeling out of place in both the mortal realm and Olympus. This struggle embodies the essence of their existence—balancing the two worlds while seeking acceptance in both. His yearning for peace highlights the importance of connection and belonging, suggesting that it is crucial for demigods to embrace their dual natures rather than be divided by them.
