Cabinet to the Temple of the Jade Emperor and convinced the Tong that his materialization heralded the arrival of Weng-Chiang. Hsien-Ko has promised the Tong that she will restore their god to them, but she admits to Romana that she knows the truth; Magnus Greel is a madman who deceived her father, and it was only due to the Doctor's intervention that Chang died an honourable death.
