The Rohirrim must constantly patrol their borders to keep a careful watch for orcs, or those in service of Sauron. In the open highlands of Rohan, a rider on patrol is set upon by Ringwraiths. Galloping at full speed to catch up to the rest of his company he must use his arrows to fight off the doom that is close at hand. The Hithaeglir or Misty Mountains in the late rays of the day, provide the backdrop to this highspeed chase.
