Other impressions I always had was that Luke was taken to dagobah when he was a kid before going to uncle owen. I remember reading in starlog that kurtz said luke was taken there immediately after him and lukes mom and leia were split up. This is why luke says the comment "there is something familiar about this place" Also that dagobah was the home planet of the sith. The scene where luke cuts off vaders head is inside what most call a cave and even some books call it a cave but it is really a temple. when luke looks inside the room where he sees vader you can see the outline of a concrete door. it is not a cave or tree. This is why it is strong with the dark side of the force. Also this is why yoda chose that planet to hide on. No one would think to look for a jedi oin the home world of the sith.

Yeah I've always wondered why the den of evil had a bulkhead in it.

You make very good points.

It would of been good if Yoda and Ben took Luke to Dagobah before Ben left with him for Tattoine. Yoda could perform some Jedi mark on him to hide him from Vader and the Emperor while he was growing up.

Dagobah could of been a once beautiful planet turned to the way it was when we saw it through the Sith leaching life from the planet to make themselves powerful.

My impression of Yoda was a old Jedi who didn't need a lightsaber because he had completely mastered the force. The Emperor was hiding away like Yoda getting Vader to do all the work. The Emperor didn't need a lightsaber either due to his power.
