The Tales of Earth-I focus on the immortals of the DC Universe. In the world of Earth-I (or Earth-Immortal), while there is only one positive and one negative universe, there have been — or will be — four Crisis events at various periods of time, with the Anti-Monitor as the main villain behind the Crisis, and the heroes of that age as his opposition.
The immortals in the DC pantheon of characters fight one another through these Crisis events, as the Anti-Monitor has recruited the likes of Vandal Savage, Tannarak, and others on his side, while the heroic immortals like Arion and Doctor Mist are his eternal opponents.
