Dal

"Referred to in the contact material from Billy Meier, the DAL's are a humanoid species who act as mentors for the Pleiadians." (Lyssa Royal & Keith Priest, The Prism of Lyra)
They are not from this Galaxy. They aren't even from this Universe but are said to be coming from a parallel universe.
Wendelle Stevens claims they look like "Nordics" or "Blonds."
