Here's a question for all your EU readers out there. I've dabbled in it, but I don't know all
the stories that are out there. Has there ever been any explanation as to
why Obi-Wan and Yoda were able to hide from Vader and Palpatine for all
those years? I mean, Vader goes out hunting Jedi all over the galaxy, how
does Obi-Wan stay hidden, on Anakin's homeworld, for 20 years without
Vader detecting his presence, or Luke's for that matter? Same with Yoda,
why didn' t Dagobah register on Vader's radar as a planet that a Jedi could
hide on?

Along those lines, what about Yoda's line in ESB about the cave, that it was
strong with the Dark Side? Was this something Yoda created as part of
Luke's training, or did the Dark Side already have a strong presence on
the planet? If so, where or who did that presence come from?

I'd love to see a story written where a young Luke visits Dagobah with Obi-Wan, for
some reason. I mean, Luke says "there's something familiar about this
place"....
