With the sets for Star Wars: Episode VIII being so far away, there was actually a rock feature that was being mistaken as a another crashed ship. It is an easy enough mistake when you look at it. The location is rather interesting and is connected to Luke Skywalker. The location:
According to people in the area the location is being called “The Mediation Rock” by the crew. There is a scene with Luke Skywalker as he meditates on this rock. The strange part is that in concept art glimpsed around the location, suddenly Ahch-To has a binary sunset while Luke meditates. I’m thinking the concept art is implying that Luke sees this when in a meditative state because if the planet had two suns it would be a lot hotter than it is. Perhaps mentally going back to the twin suns of Tatooine centers the old Jedi?
We aren’t sure if this is relevant but supposedly the stand-in for Luke was a young male.
