Help With Locating Voidwatch NM Spawn Location

I am having a lot of issues with finding the spawn for the VWNM in Quicksand caves. On ffxiwiki it says map 3 but map 3 is only listed with an entrance from eastern altepa desert. So when I finally made it there (through map and 2 then exit to the desert) it was blocked by a ledge. But then I thought why not use the cloister warp so I did and I was able to zone out there but I dont have access to map 3. Help is so much appreciated. This has been 2 hours of my time. I have tried unity warp, skcnm warp and survival guide.

To get to that one specifically, it's western.

Quick question for you guys if you still have eyes on this thread. While progressing through the cities of Voidwatch I was able to do each nm once and progress to the next stage. But here in Zilart I did all VWNM's and when I spoke with the npc he did not give me abyssite upgrades, was that a campaign of some short when I did cities? It was over a year ago and I only did them because of wings.

There's mini quests in between you have to view. You have to go back to rabao after those 3 and back to kazham after those 3 then back to norg.

ah so the cutscene allows for me to get credit for the kill. I was hoping it wasn't a proc system. Thank you. Guess I'm going back to kill them.
