If you look under eqatlas, and look t the Temple of Droga inner Sanctum map, it is numbered as 1 on it. The room has 5 spawns in it, 2 that guard the entrance, 4 around the pool outside. Low aggro range, but pacification always helps.
You can invis all the way down, move to the hallway just south of #2 and start pulling from there. You can single pull everything there to clear your way into the room. Inside the room you will find an oven. King spawns at the spot to the right of the oven (or did when he spawned for us).
The mobs are pretty easy and if you have a capable shaman they can both slow and keep you healed. Max hit of about 210 or so. The trick is that they do hit pretty fast. Once slowed they are quite gimp however. Fairly decent exp as well. At level 63 I went from 34% to 82% in just under 5 hours, and a couple of the others that were running AA got almost 2 AA. While that's not quite as good as upper tier zones, it's certainly good enough to make the camp worth it. Also that the camp is easily duo-able by a shaman + a melee.
