The planet Eden has entered its imperial age, where new technologies carry new ideologies across the globe to clash with religious fervor. To the north, the proud and traditional Kingdom of Valenta expands its conquering fortress of ice and jungle. To the south, scientific, progress-minded Imperial Estia marches out of the desrt to enlighten their neighbors by force. On every side, waves of tribal peoples beset them all. This is not a reign of kings, but a reign of death. Welcome to Regnum Interrus. The die has been cast.
