In Pacify the Centaur, you must kill the centaur camping north of Freewind Post.
To Get This QuestEdit
The centaur are located directly north of Freewind Post up against the cliffs that mark the edge of Thousand Needles, an area known as Splithoof Crag. It is a large camp and the different types of centaur are scattered through it, though the Galak Scouts seem to be more scarce than the others.
<name>, I entreat you to hunt these centaur down. They shall feel the wrath of our revenge. Attack the centaur camp to the north of Freewind Post! Let wrath guide your hand!
Come now <name>, I know you haven't killed your share yet. Hunt them down, and I shall give you a reward for my gratitude.
For my gratitude, this is for you, <name>.
