In around 429 BCE, Sosipatros was hired by the Spartan general Brasidas to wait for the misthios Kassandra at the Statue of Artemis for her and direct her to where Brasidas and her mother, Myrrine, were. Sosipatros, however, had been paid off by a third-party to obstruct Kassandra. After being defeated in combat, he told Kassandra where she could find Brasidas and her mother, before she finished him off.
- If spared, Sosipatros will roam the world until encountering Kassandra again.
- When slain, Kassandra retrieves a letter from Brasidas, as well as a ring, regardless of when Sosipatros is slain.
- Sosipatros carries a shield emblazoned with the emblem of Phokis, and wields a blade identical to the Epsilon Blade.
