Give Sara Timberlain the Stormwind Armor Marker.
For your shrewdness and valor, I have a marker here that is good for one piece of armor. I want you to take it to Sara Timberlain at the Eastvale Logging Camp. Give her the marker, and she will fashion the armor for you. And after you receive it, [player], use it in the defense of Elwynn.
The Eastvale Logging Camp is beyond Guard Thomas' post to the east.
