I been thinking about somethings that we still don't know about some of the major characters. For instance, what is yoda?(i read somewhere that he may be something called a whill) what planet is he from and is he the last of some species that died out due to a cataclsym or are their others like him. Where the hell is Obi wan from?(In the novelization of A new hope he said something to luke about a duck, was ben orginally intended to be from earth?) i thought i saw ET's species in the senate in one of the prequel. did anyone else see them.

I think the ET aliens are a joke between Lucas and Spielburg (sp?)

I have no clue about Obi-wan, and don't believe the crap you hear about Yoda, nothing is officially known.

All I could dig up was some info from the CUSWE (http://www1.theforce.net/CUSWE/search.asp?search=Obi-wan) saying that he was taken from his family from an early age for his Force affinity and was born out of a moderately wealthy family. Hehe, just another of saying he was a middle-class commoner.

As for Yoda, nobody is really sure about him, Lucas has been pretty secret on the green dude. There was Yaddle also though (same species as Yoda), so I suppose they are some really rare species with a rare gift of high Force affinity, something like the Fosh (Vergere) and their special tears.

Even if he did say something about ducks, there are ducks in the Star Wars universe. You can see them in one of the movies.
