After killing four sets of assassins that have been sent to kill you, you will acquire four pieces of a map. Collecting all four pieces will complete the map. For the map segments, the assassins that attacked me appeared in the following locations:

• Westcliff,
• The Bandit Coast,
• Bloodstone and
• Rookridge.
  Once the quest has been updated, you are able to select it as your active quest and follow the gold dust into Brightwood. From here you should be able to follow the trail all the way to the entrance of the Forsaken Fortress.

Continue along the path until you reach the ruins of a castle crawling with bandits, here you will get an updated quest message telling you to kill Darius Zing. Kill all the enemies in the area and Darius will run off. Follow him and you will be attacked by more bandits. Dispatch them and continue to follow Darius.

The third time that Darius stops, he will not run away but join some highway men and attack you alongside them. Finish him off to complete the quest.
