If you come across an abondoned fort full of ghosts, don't you want an explanation of it? But seriously I'd like to know what the random part is....
Can you link one please?
I've found several Forts full of ghosts, but they all have stories behind them (One was a prison destroyed by a monstrous storm, there's also Labyrinthian, which, along with Saarthal, is one of the oldest cities in Skyrim, and housing a powerful Dragon Priest, as long as the source of all masks)
In fact, the usual reason for Ghosts is a Dragon Priest or powerful Draugr Overlord, who's stories have been "Lost to Time" (As in, they have a story, but it's no longer decipherable). There are a lot of places like that in the real world (*cough*Stonehenge*cough*)
