Faction hit to Tunarean Court is -10.
There are 16 "a drixie thane" spawns in the zone. They do not share spawn tables with other mobs in the zone (will always respawn as either another drixie thane, or Lord Prismwing). They roam all over the place - the area around the port-in, the areas north and south of the lake, and all around the western half of the forest. They don't seem to roam to the eastern half of the forest.
If you're after the Hunter achievement, then just keep killing these and he'll eventually spawn. A tracker will help greatly as this mob type is difficult to see in its environment. (If you're after one of his quests, then I'm not sure what to suggest because killing the PHs will quickly decimate your faction with him at -10 per kill.)
Not sure if just some of the spawns are PHs, or if all of them are... Either way, I killed 121 "a drixie thane" before Lord Prismwing spawned...
