"Vega is the alpha [or brightest] star in the constellation of Lyra, even though it is actually closer to Earth than it is to the other star systems in the Lyran constellation. Vega was one of the first Lyran civilizations to develop a unique and cohesive identity which assisted in seeding and colonizing many systems, including Altair, Centauri, Sirius and Orion." (PoL)
Physical Characteristics of the Vegans:
a) the standard Vegan
six to seven feet tall, darker skin (sometimes copper-toned), non-Caucasian, black hair, very large eyes with dark pupil and iris and one lid. Blood is green.
b) the "non-human"-type Vegans

(Vegans used to colonize. they colonized Orion, Sirius. Sirians merged with locals and "forgot" their vegan descent. Orion => a lot of non human humanoids were active over there, e.g. in the Bellatrix region. // Empire, etc... were Orions from vegan descent.)
