In the third century, also known as 217, it was believed to be a period of great happiness for humanity. However, despite Rome's status as the dominant global empire, political corruption, barbarian invasions, and economic strife from ongoing overseas battles are causing increasing turmoil. The empire's decline is gradual but inexorable, and the killing of Emperor Caracalla marks a significant turning point in history. The creator of the medieval-themed fantasy "Pilgrim Jager" presents a story of a fantastical and violent ancient world.
