Most Urdar lived in or beside the Forest of Dír, a great taiga woodland in western Urd. They hunted and trapped throughout the area, spending their winters in well-insulated clan centers by the great river called the Urd Rush. Their most famous son, Hoarmûrath of Dír,had become a Nazgûl and subsequently had conquered all of the surrounding regions. Thus, Urd was reviled by most of the Hildor in north-central Middle-earth.
