Sirus is the head chief of Planet X (Planet Nibiru) and second-in-command of the Nibirian leadership. He is Alpha Iris's right-hand man and voice of reason — a loyal servant, a wise counselor, and one who gathers information at exceptional speed.
In the beginning of the story, Sirus helped Alpha Iris become ruler of the universe. He is always offering Iris warnings and advice, watching carefully and speaking wisely when others would stay silent.
However, as the story progresses, Sirus begins to see that Iris's actions contradict what the almighty god's scriptures preach. His loyalty to Iris comes into conflict with his deeper devotion to the gods themselves. Devoted to 'lives' of service in order to be seen as righteous and worthy before the almighty gods, Sirus ultimately makes the decision to go against Iris — choosing what is right over what is loyal.
Sirus also appears in the New Lost City series, carrying his role as a spiritual force across the Planet X Universe.
Loyalty vs. Righteousness: The central tension of Sirus's arc is the moment when his loyalty to Alpha Iris runs headlong into his deeper commitment to divine truth — and he must choose which matters more.
