When the Cult met for the first time after quite a while at the Sanctuary of Kosmos beneath the Sanctuary of Delphi in Phokis around 431 BCE, Lagos was there as well as Pausanias.

As a reminder of this, and proof of where Lagos' loyalties should lie, Pausanias gave him his ring. The Sage of the Peloponnesian League branch of the Cult, Pausanias, targeted Lagos' family, and threatened them with torture and death unless Lagos' did as he was told. He first considered them merely as 'business partners', but eventually they showed their true colors. Cult of Kosmosĭue to his influential position, Lagos was approached by the Cult of Kosmos sometime before the Peloponnesian War. ĭue to this friendship and Lagos' aid, Brasidas wanted to free Lagos from the Cult of Kosmos' grasp when he came to Arkadia with Myrrine and her daughter, the Spartan misthios Kassandra around 428 BCE.

The two kept in contact throughout the years and grew close, with Brasidas even referring to Lagos as a "dear friend." In turn, Lagos mentioned how Kassandra's words upon their meeting reminded him of Brasidas when he was her age. Whether their friendship began before or after this incident is unknown, but this deed made enough of an impression on Brasidas that he reminisced about it years later during the Peloponnesian War. When the soldiers serving under the Spartan general Brasidas were starving, Lagos managed to get supplies to them. An Arkadian farm owner, Lagos rose to become the leader of the region during the 5th century BCE, his wife Philonoe and his son Niloxenos beside him while he kept the "breadbasket of Peloponnese" full.
