Провинции Империи: Остланд

Lord Haarhus, «Ostlanders have a reputation for being bull-headed, and, among their Imperial brethren, it is an open question as to which would win in a contest of wills between a Dwarf and an Ostlander who has made up his mind on a matter. Descended from the ancient tribe of the Udoses, the Ostlanders have been known for mulishness since the earliest days of the Empire».
Если кратко — от их упрямства (в англ. bull-head).
