The Yak Trader was originally a goatherder who had found the Crown of Gengkhis Khan inside a box in the ice cave at the base of Mount Karakal.

Scrooge, had in the past, maintained a company in the foothills between the Himalayas and the Kunlun Mountains called "McDuck's Yaks". When the Sherpas at Scrooge's Yak Farm in Ladakh heard of a goatherder who had found the crown, Scrooge traded his yak farm for it.

Scrooge returned to the Himalayas once again, to ask the Yak Trader where he had found the Crown. In return for that information, he sold him the yaks that he and his nephews used as steeds.
