The Barrow-downs west of Bree were once a haven for the Rangers of Cardolan, until the plague swept across Middle-earth and destroyed the last remnant of those Dúnedain. After the Rangers of Cardolan perished, the Witch-king sent fell spirits out of Angmar and Rhudaur to inhabit the remains of the dead buried beneath the mounds, giving rise to the Barrow-wights. Since then, the Barrow-downs have had an evil name as a place of terror.
A few places within the Barrow-downs, such as Othrongroth and Ost Gorthad, are known as places of the greatest dread. Another of these terrible places is Haudh Iarchith. Once the clan-barrow of a great and wealthy family, it has now become a den of Angmar's Dead. The hunters of Bree seek to drive the evil from this place, but few among even them have the courage to face the wights of Haudh Iarchith.
