In 1565, under the name Durankon Rankov, he worked for the ruler of Savoy as ambassador. He was sent to Burgundy to negotiate peace, but when he got there, he met the Immortal, Amanda. His offer to end a hostilities in a marriage between Christina of Burgundy and Phillip of Savoy was well received, but Rankov was not interested in peace, his interest was in the dowry that he should take as a sign of good will return to Savoy. On the way, he murdered his companions, and tried to hide the loot, then report a diplomatic failure. He was, however, surprised by Amanda, who challenged Rankov to duel. They fought, but when he was pushed down a hill, she let it go at that, and brought a dowry to Savoy.
