Background
The Temple of Artemis at Ephesus was one of the largest temples ever constructed, dedicated to the goddess of the hunt and rebuilt multiple times after fire and flood. Its sheer scale and the wealth of its treasury made it a destination for traders and pilgrims across the ancient world. Ephesus sat at the mouth of a great river, and commerce flowed through it like the tide.
In 7 Wonders, Ephesus opens with a Papyrus (manufactured good) production, reflecting its scholarly and mercantile reputation. Its Wonder board converts that commercial energy directly into coins.
