*bzzt* SubRosa has the right game, with her suggestion of a Fallout 4 location. I'll drop a hint: it has to do with follower quest.
Now that you mentioned the follower...does it have to do with Nick Valentine? The final location, where his quest takes place, is called Andrew's Station, though I don't recall this particular stage, I know there's some underground bar, so maybe it's the same place.

You can see that mountain from most of Skyrim, and she may well have been outside Windhelm. I could only determine North-eastish and looked for a high enough place you could see that far. Shearpoint is more North and Windhelm more to the East.
Why don’t you just post another?
