Another confirmation for Faelin. I started camping 1500, 500 and after an hour Faelin spawned. Note taht 1500, 500 is the exact spawn point so it pays to stand back a bit. I recommend standing back and looking toward the location SE. I killed 8 pawns, that popped every eight minutes like clock work and then Faelin popped. She despawned as soon as I gave her the not.
