Troyian

The Troyians were a humanoid race native to the planet Troyius in the Tellun system. They were distinguished by their green to blue-green colored skin.

Troyians had a history of war with the Elasians, from the neighboring planet Elas. In 2268, in order to establish peace between the two cultures, a marriage was arranged between Elaan, the Dohlman of Elas, and the Ruler of Troyius, which was accomplished with the assistance of the United Federation of Planets. 

A male Troyian named Purdi lived in San Francisco on Earth in the 2280s, and owned a bookstore, Purdi's Book Emporium.
