Where is Perdition Rock?

I don't know if I should put this in the Quest forum, but IMO it's a pretty basic question. I just reached Amnoon Oasis and it's the farthest I've gotten with any character (I'm afraid of commitment) and I was wondering where Perdition Rock was? I have a map of what I believe to be the entirety of the Crystal Desert, which I got from the "Crystal Desert Collectors" thread, but I cannot find Perdition Rock. Also, the Interactive Map on the mainsite does not go past Sanctum Cay.

Any help is appreciated.

Perdition Rock isn't in the desert it is on the islands way far south and westish.

Perdition rock is in the molten lava area (southwestern)... right outside ember camp.

It's right after about four of the missions around draknor's forge (?)... something like that... but yea
