Lore

Long ago, the Barrow-downs fell under a shadow of evil, and the Witch-king sent fell spirits out of Angmar and Rhudaur to stir the bones of the dead which lay beneath the green mounds. Something has disturbed the Dead that Walk, and you must lay their bones to rest.

The wights of the Barrow-downs no longer hold any terror for you. Now you just find them deeply unsettling.

Objective

Defeat 40 wights in Bree-land

Reward

Title: Bane of the Barrows
