Argonaut Expedition
The collective event launched by command, sustained by many skills and shaped by taking the Fleece and returning with its costs.

Overview
The Argonaut expedition is completed collectively by the many companions Jason gathers. Some crew members have individual roles, while others appear through shared rowing, counsel, mourning and combat. Ancient works do not preserve one identical roster, so the expedition represents the common voyage and its decisions without claiming that every tradition names the same complete company.
