*disclaimer*
The only time I've spent in this zone is camping this Mob, so I honestly don't know if faction will change the non-kos mobs if you grind in this area. There are no faction hits at The Dark Lady camp.
Getting to the camp all you need is IVU (invisibility to undead), anything that sees through that is either non-agro or a Rare mob, I've never had to fight my way to the camp.
Getting to the Camp
Upon zoning in, head up the stairs and open the large door. From here you will see another set of stairs with Aten Ha Ra standing there as a quest NPC. Instead of going up that stair case to her, look to the left and you will see a door, go through here. From here you are in a hallway which will forced to go right. Then continue straight past the 4-way intersection. The next intersection is a 3-way, where you'll want to go left. Then you are force right into a long hallway in which you will pass the first PH for The Dark Lady. The end of this hallway is a door that opens into a large circular room. Upon entering turn to your right, along the wall you will see a pillar in the wall and what looks like a root coming out of the wall. This is a pretty safe spot, good for a camp, campfire, afking. If you AFK use IVU before you go.
The three spawns should be marked on your map, they are accurate. I don't know for certain if you can have more than one The Dark Lady of her up at any given time. Due to this I stagger the spawns.
The first PH you actually passed by, getting to the camp. There is one wandering mob near it that wanders out to the circular room. There are two more static mobs in the long hall, near the door to the circular room.
The second spawn is to the left when you enter the circular room. There are two mournful specters along this wall. The PH is the second one from the door.
The third spawn is at the landing of the second ramp/staircase up. So from the camp you will go up the ramp until it gets to basically the second floor. Looking to your left you will see it continues up. On that landing there is a static mournful specter, this is the PH. There is one wandering mob that paths from the next level, past the PH and onto the second floor landing.
Staggering the Spawns
If you're only after these mobs drops then I suggest staggering the spawns. The re-spawn is the standard 17m45sec-ish. What I do is kill one PH, wait five min, then kill the next, wait five min, and finally kill the third.
You can actually IVU and kill the PH at their spawns with relative safety. Only spawn #1 and #3 have wanderers that you need to be aware of. It's also to note that The Dark Lady's agro range is probably 3-4 times bigger than any other mob in this area. Due to this, with PH #1, (The Hallway PH) I suggest killing the two mobs near the door to the circular room.
If you're also EXP'ing here be aware that there are quite a few mobs if you want to hit all three spawns in the 17m45sec re-spawn time.
I hope this helps someone, and GL.
