Major Lorne discovers a civilization whose flag features McKay's face in glorious detail. It turns out that the nation of Geldar (named for a girl McKay used to stalk dated twice in college) and its rival nation of Halona are the results of Ancient Lantean social engineering, which McKay and Sheppard mistook for a computer game. In the two years they've been playing, Geldar has flourished in technology, achieving dirigibles and bicycles and inheriting McKay's fear of citrus, while Halona has advanced militarily - and their involvement has brought the two nations to the brink of war.
