I've recently been interested in the dark side presence in the cave of Dagobah where Luke "faces" Vader/himself. I know the back story that Zahn has written and find it interesting. There are other threads similar to this that have been started, but they are closed for comments and I wanted to take a slightly different angle. Is this phenomena unique to the cave of Dagobah? Is it possible that there is a similar presence/tremor/shadow where the 2nd Death Star was destroyed (i.e. where Palpatine was slain) over Endor? Or in other areas where Dark Jedis have been slain? Thoughts?
