Sandy O' Sullivan was a member of the Irish Brigade during World War I, which aimed to give Ireland the independence from Great Britain. She was also a former student of Professor Foster, and the two were in love, but their different political side kept them separated, but they helped each other in a couple of occasions. Draka saved her from an ambush while travelling to Transylvania, in search of a legendary weapon belonged to the Teutonic Knights, which would have helped her cause. Some time after, she went live with Draka in his subterranean realm, Shamballa, where time is almost stopped, working as Draka's assistant together with her loved Edward Foster.
