Darmabala
Darmabala (1264–1292) was the second son of Crown Prince Zhenjin and grandson of Kublai Khan, wedded to Dagi. After Zhenjin's death in 1286 Kublai made him a likely heir with a command, though Marco Polo called him rickety. In 1291 Kublai sent him to govern Huaizhou, but he fell ill on the way, returned to Khanbaliq and died in 1292.
His sons Khayishan and Ayurbarwada both became Yuan emperors; Khayishan's accession in 1307 brought Darmabala posthumous honour as Emperor Shunzong.
