For ages, the Middle Empire ruled the continents of Ultera, and peace held.
In -22 before the Great Advent, Emperor Thoram chose the path of enslavement. He introduced a tax paid only by the other continents, while Mediotera was treated as supreme.
With mathematicians and scientists, Thoram created the calendar known today and established year 0 as the Great Advent, declaring his reign eternal.
Thoram died at 74, and emperors followed. After 389 years and 9 emperors, the Prescient Empire fell in 367, when the Great War liberated the peoples of Ultera.
