Biography: The Tōitsu Emperor, known to some outside of Daitō as Emperor Sōnosuke, was the Emperor who reunified Daitō in the mid-to-late 15th century. Like the Heiwa Emperor before him, he would spend the remaining years of his reign stabilizing the state and consolidating his position, though he would launch an invasion of Rusan as well, bringing the majority of the island under the rule of the Empire before his death, though some holdouts remained into the mid-15th century.
Starting in 1485, Sōnosuke led an army beyond the Idaina mountains, first striking south before turning his sights to the west, to lands lost by his predecessors. He would prove successful in retaking imperial territories from before the interregnum, but, on the eve of 1490, he dedicated himself to a new goal. He would fulfill the dream of his forebears and establish an Daitōjin Empire stretching throughout all of Northern Ardia. While he would certainly make significant progress in achieving this goal, his death in the battle of Kohei in 1498 proved to be the end of this goal. His heirs would continue the expansion of the Empire, but mostly to ward off further threats. Modern Daitō, being a direct continuation of the Empire under the Tōitsu Emperor, maintains claims on not insignificant portions of this realm, though it formally abandoned it's claim on lands within Rokkenjima in the 1960s.
The Tōitsu Emperor is venerated in many sects of the Ishitic faith as either an incarnation of the war god, Kashima, or as a lesser Kami (spirt).
