The Hillmnen are a distinct clan of humans living within the Yeoman's Little Hills. They do not consider themselves part of the official Yeoman structure, although they do tolerate the Yeoman government so long as it does not interfere in their affairs. They are a fierce and proud race full of tradition, culture, and history. Negotiations are currently underway to strengthen the ties between the Hillmen and the Yeomanry proper.

Hillman was a famous British automobile marque, manufactured by the Rootes Group. It was based in Ryton-on-Dunsmore, near Coventry, England from 1907 to 1976. Before 1907 the company had built bicycles.
