Has anyone gotten this and found it's actual location? I'm assuming it was added via update 13 as any sites that list survey locations don't show there even being an alchemist survey for the rift and the lost treasure addon doesn't have it either.
http://esomap.uesp.net/ - I use this to find all my writ locations. I have gotten and used the writ you're talking about, so it is accessible, but I can't remember well enough to give directions.
