The Toha dynasty is the dynasty of Hallanbor that followed the Cylor dynasty in 1559 OE and lasted until the rise of the Mayun dynasty in 1974 OE. Lasting for 415 years from 1559 OE to 1974 OE, it was the longest of Hallanbor's three dynasties.
The end of the Cylor dynasty was marked by regent Frederick of last Cylor prince Ellarmen, who was underage. Frederick wed the juvenile ruler to his daughter in spring, shortly after which the boy fell ill. The prince died only six months later in December of 1559 OE, but his father-in-law had already been effectively ruling Hallanbor in the meantime.
