Vlandia
They came from overseas, mercenaries and adventurers, speaking the tongues of many lands, taking the empire's silver to guard the frontiers against the unsubdued tribes of the interior. They took their name from one of their first warlords, Wilund the Bold - Valandion, in Calradic - and became known as the Vlandians. Their heavy cavalry, second to none, ran down the Emperor's foes from the Aserai wastes to the distant steppes. But the empire never had as much silver as it needed, and treasury officials soon learned that it could pay its mercenaries with land grants and titles. This was perhaps not the most far-sighted of policies. The Vlandians settled, married, planted farms, and built fortresses. It was not difficult, during the recent interregnum, for Osrac Iron-arm to declare himself king, independent in all but name. He seized the imperial capital of Baravenos and the lands along the coast, and that was how the west was lost to the empire.
