Hey guys, it's FlaminKnight here to provide you with a quick guide to where or how to find this npc known as Thalorien Dawnseeker who is needed for the Battered Hilt quest chain.
To get to the location of this npc, go to Dalaran > Shattrath City > Isle of Quel'Danas
Here is my video to show you the location of him:
However, if you don't want to watch the video, here are screenshots of his location: Thalorien Dawnseeker Map Location
The second screenshot has a link since the image is too big to fit on the post, but hopefully it should help you find him ^_^
*Side Note*
If you have a hard time seeing him on the ground, do a /target macro: /target Thalorien Dawnseeker
Copy and paste this into a new macro, set it on your bar and click the macro and it should target him if you are close to his body.
*Side Note No.2*
Make sure you are NOT in a raid group when you are doing this quest, or else it won't count.
