Ewoks

One funny thing I've noticed about every version of the "Star Wars" RPG that I've read (which is all the d6 and d20 versions, but not the FFG ones): they all say that Ewoks are first discovered around the time of the Battle of Endor.

But that's not so.

In "Return of the Jedi", C-3P0 already speaks the language of the Ewoks. True, he notes that it is "a very primitive dialect", but still that means that at some point someone had sufficient contact with the Ewoks to bother placing the details of the language into a droid's translation circuits.

Most likely, that means that there are other colonies of Ewoks, potentially much more integrated colonies of Ewoks, somewhere out there in the galaxy. Or, of course, the Ewoks on Endor could be the last remnant left over from some horrific Sith atrocity from one of the earlier wars in the galaxy, one so long ago that they have been entirely forgotten.

Which would, of course, make it even more tragic when the Rebels' destruction of the second Death Star unleashes ecological devastation on their last remaining homeland.
