Nereus
A truthful and gentle ancient sea god, the Old Man of the Sea born from Pontus.

Overview
Nereus is the first visible entrance into Pontus’s old sea-god branch, called the “Old Man of the Sea” by Hesiod. The poem stresses that he is truthful, unlying, trustworthy and gentle, linking justice and kindly judgement to his character. He later fathers the Nereids with Doris, but this account keeps only the core identity needed to bridge later sea stories rather than creating the full catalogue of fifty daughters. He remains distinct from both Poseidon, the Olympian ruler, and Pontus, the primordial Sea.
