Echion was well-versed in secrecy, and for this reason Pactyas tasked him with a special mission: given that everyone ignored the man, Echion was told to watch everything, see everything. And make sure the presence of their Order in Makedonia remained secret, especially from the the Cult of Kosmos. Echion was further told to keep a keen eye on anything related to the Cult, and report any sign or rumour of their presence to Pactyas as soon as possible.
In 429 BCE, Echion found Hylas and recruited him to the Order's service. Hylas' exuberance and desire for revenge ultimately led the Spartan misthios Kassandra to discover Echion. As he was a member of the Order of Hunters, she slew him.
- Echion shares his name with multiple figures in Greek mythology.
