Men of Sol
Strictly, a member of that human race which developed on Terra (Solomani Rim 1827) from the original human stock (H. Sapiens). The term Solomani is often used to refer to members of the Solomani race (or, more palatably to some, to members of the human race of Solomani descent) or to members of the Solomani political movement. Its original meaning is obscure, but the word seems to have derived from either "men of Sol" or "sole men".
After the Solomani developed jump drives in -2431, Solomani humans scattered to the stars in several waves. Early colonization efforts first settled the worlds closest to Terra; the later conquest of the First Imperium and the establishment of the Rule of Man sent more Solomani humans out primarily to occupy former Vilani controlled regions.
Alternate: The original human race from Terra. The typical Solomani is about 1.8 meters in height and weighs about 75 kilograms. Solomani blood types include A, B, O, M, N, and Z, but A, B, and O are dominant. Many modern Solomani believe that pure Solomani - the true original humans - are superior to all other humans, and thus are best fit to rule the Imperial region.
