Mongarian

The Mongarians were a species of traders.

For Peri's birthday, the Sixth Doctor took her to Las Vegas in 1971 to meet Elvis Presley, only for him and Elvis to be kidnapped by the Mongarians. Stopping them from making several clones of Elvis to sell throughout the 20th century, he ensured that Elvis was returned just in time for his performance at the Hilton. (PROSE: Priceless Junk)
