Tyshu Daiyang

Lord of Horse Tyshu Daiyang, Earl Rainbow Waters, was a Harchongese nobleman, commander of the Mighty Host of God and the Archangels, and the first leader of the independent Eastern Harchong.

He was chosen for his command over several other more senior lords of horse. His senior aide and adjutant was his maternal nephew Captain of Horse Medyng Hwojahn, Baron Wind Song.

When Harchong refused to allow the Host's enlisted men to return home, Rainbow Waters and Wing Song remained with their men, despite other officers abandoning them. As a consequence, they lost their estates.

After the Harchongese serf rebellion in 903, Rainbow Waters and Wind Song led the Host into the eastern portion of North Harchong and established a provisional government nominally under the emperor. However, the emperor's denunciations and refusal to work with the Host led Rainbow Waters to declare East Harchong's independence and establish a parliament to write a constitution.
