The Northwind Highlanders were founded in 2362 with the formation of the First Kearny Highlanders by Clan Stuart, a group of Scots that included the descendants of the last vestiges of the original Scottish regiments on Terra.
The Highlanders achieved fame far and wide through human space even before the Star League was formed. Later, they were of the League's more respected units by the SLDF, and the Royal Black Watch members who protected the First Lord were mainly recruited from the best Highlanders.
