Pexmit is a neutral recipe vendor located in Dae'gun in Mount Hyjal.
He can spawn at multiple locations. I found 3 so far. Look around, he is usually a bit hidden.
It is possible there are more spawn points.
I found him inside the house that has fallen over in Dae'gun and inside a small hut, on the 2nd floor.
You can spam this macro while you walk around. When he is near, it targets him and puts a skull on him. If you have never made a macro, type /m in the chat and press Enter, click New, give it a name and paste these three lines into it.
