So where is southwest? Where are these Forgotten Ruins or what are they near? Now the map interface in skyrim VR doesn't appear to have a compass. OK option 2 of make your way to the 'Forgotten Ruins'.
I've tried entering many many cities - check check and check.Alternatively, you can make your way to the 'Forgotten Ruins' in the south-west corner of Skyrim. If you’re Level 5 or above, you’ll be approached automatically by a courier when you enter any city. Based on the instructions from the above link I've installed it with Vortex but I can't seem to start it.
I checked back and there are a number of people successfully running this story quest mod.
