The Stavropolous River is located in Velo, Greece. Dante Vale, Sophie Casterwill, Lok Lambert, and Zhalia Moon travelled whilst searching the Argo and its treasures including the Hoplite Titans of Jason. Whilst diving down to investigate the ship, Lok nearly drowned after his air tank was cut off. It turned out that the Argo was not sunk here but that the ship belonged to Atalanta, one of the bravest of the Argonauts. S1E10
