|Cause of Death||
Emperor Duzong is the heir to the Song Dynasty. He is spirited away by Loyalists in 'The Heavenly and the Primal' and is guarded by Lotus in 'The Hunter and the Sable Weaver'.
Marco and Mei Lin track him down and bring him to Kublai after fighting and fleeing from Lotus, the Emperor's bodyguard. Despite Marco, Chabi and Jingim arguing for leniency, as well as the boys own pleas, Kublai suffocates him to death by smothering him whilst hugging him.
His body is later seen hanging by a noose, afterwards a Mongol cuts him down after there are revolts by those loyal to the Song Dynasty.
