Fayna ruled Champasak for two decades until his death in 1811. Prince Nu, son of Nomuong and grandson of Sayakumane, was made to succeed as King of Champasak. Khamsing, son of Fayna, refused to be a subject of Champasak and requested the Siamese court for himself to secede from Champasak. Bangkok then made Khamsing as the first governor of Yasothon, again as a direct vassal to Bangkok. Only three days after his coronation, King Nu of Champasak died in 1811 and was succeeded by his brother Manoi.
