The Teichos of Herakles was a fortress dedicated to the legendary hero Herakles, located atop a peak in the Achaean region of Erymanthos Peaks, Greece. It served as the headquarters of Polemon the Wise, the Sage of the Silver Vein branch of the Cult of Kosmos.
When the Order of the Storm branch of the Persian Order of the Ancients came to Achaia searching for Kassandra, Darius and Natakas, the men serving the Order captured locals and took them to the Teichos. There they were questioned about 'yellow-eyed man' and 'Eagle-bearing misthios '. Natakas asked Kassandra to help the people. While rescuing the people, among them Kleta, Kassandra found a letter addressed to the Cult of Kosmos from the Order of the Storm, signed by the Tempest.
