Tiresias is first referenced in The Circe Saga, when Circe tells Odysseus that she cannot help him return home, but she can send him to the land of the dead—where Tiresias waits. As the only soul who retains his prophetic abilities even in death, Tiresias becomes Odysseus’s only hope for navigating the wrath of the gods. His role is that of a harbinger: he does not offer solutions, only truths that cannot be escaped.

In The Underworld Saga, Tiresias appears in the song No Longer You, delivering a vision not of triumph, but of tragedy. He describes an alternate universe where Odysseus could have made it home with his crew intact, but clarifies that this is not that universe. Instead, he predicts a journey marked by loss, betrayal, and the eventual transformation of Odysseus himself. The line “A man who gets to make it home alive, but it’s no longer You” reveals the brutal emotional shift Odysseus will endure—a foreshadowing that rattles the hero’s moral compass.

Later fan theories, supported by the recurrence of Tiresias’s musical motif in Six Hundred Strike, suggest that this was the precise moment the prophet foresaw: the death of hundreds at Odysseus’s command and the breaking of the man he once was. Though Tiresias returns briefly in The Wisdom Saga during one of Athena’s timedives, his most powerful role lies in setting the stage for the moral descent Odysseus embraces, confirming that prophecy, while truthful, is rarely comforting.
