ToME WikiThis quest is gained in Bree after the player has completed either the Trolls Glade or Wight Grave quests. The Danger Level of 40 is probably relatively accurate here.1
Monster: Uvatha the Horseman is the least powerful of the nine Ringwraiths or Nazgul, and as such has the usual attributes. For information on how to defeat Nazgul read this. Beware, unlike other quests, there is no entrance stairs for this one: Uvatha the Horseman will be generated somewhere in Bree as soon as you have received the quest from the mayor.
The quest is completed when Uvatha the Horseman is "dead". Go to the mayor to collect your reward. This is 6 sprigs of Athelas, a cure for the Black Breath, which you might need now.
