Vladimir was exploring in the Ire Mountains, he came by way of the Gnoll Watch Tower. I had heard (via shout) not to go into the desert since the AT's were not working properly and there was no way out so I decided to go back the same way as I entered but was surprised when the AT from Ire Mountains to Ire Mountains (Gnoll Watch Tower) took me instead to Spirit Dunes. You can go back to Ire Mountains from Spirit Dunes, but you cannot currently get back to Ire Mountains (Gnoll Watch Tower).
