Dorians
In his book, the coming of Tan, Riley Martin (1946-2015) describes how he was taken on board of a huge egg-shaped "mothership" in the vicinity of Saturn. On the mothership he learned it was inhabited by seven different species of intelligent technological life forms, of which the Dorians are one. He mentioned that the Dorians looked like blonde-haired, blue-eyed humans.
No other authors mention this species. Many researchers question his credibility.
(The word Dorian usually refers to a group of people in ancient Greece and their architecture. The term is also used in the context of music, referring, inter alia, to a minor scale in which the 3rd and 7th note are lowered).
