Lyssa Royal: "Also within the Lyran you have a broad type we would call Caucasian who are light-skinned, light-eyed (the darkest eyes were perhaps a light brown, but that is uncommon), hair ranging from almost white to a light brown (but anything in the brown range was unusual). These entities' body types would be anything from ectomorphic, (thin) to the mesomorphic (muscular). This is the broadest category. Most of your genetic forefathers were from this Caucasian category. Your diversity began with some red-head influence as well as some giant influence, but those are secondary compared to the Caucasian influence, which is primary. "
[Lyssa Royal: Excerpt of "Galactic Family, An Overview of Genotypes"]
It is believed that these Lyran Causians started migrating and colonizing other worlds, already millions of years ago. These worlds include the Pleiades, Hyades, Procyon, Tau Ceti (Norca), and others.
Many of extraterrestrial 'Nordics' or Blonds that are encountered are descendants of the ancient Lyran Caucasians.
These Lyran Caucasians and their descendants belong to the 'Standard Terran Humanoid' type, meaning they look like us, and can walk among us unrecognized. (See: exophenotypology and Humanoid phenotype).
