After watching Rogue One again, I pondered upon the location of the temple on Mustafar at which Darth Vader is seen in meditation. As we all know, Darth Vader underwent a battle on this planet that did not end in his favor (to put it lightly). As he is a dark side practitioner, and the dark side feeds on passion, it makes sense that he would meditate in a location where he undoubtedly had some strong emotional connection (not only was he mutilated, but he also believes he murdered his beloved just prior to this).
But it is the precise location of his temple that I am curious about. Based on this shot from the film:
the temple is built on the top of a lavafall. During Revenge of the Sith, near the end of the Darth's battle with Obi-wan, they fight on a lavafall. It seems to make sense that he would choose to build a a temple near this location, so he could overlook the spot where his transformation took place.
Is there any evidence to support or deny the claim that this is that same lavafall?
