^dont worry i could care less about time lines b/c this series isntment to keep tabs on them
each Zelda might hint back to another but they are really ment to be taken as one unit by itself and not linked unless directly by the game itself
the best example to put it in perspective is like teh different series of a comic book, sure they all deal with similar stuff but in teh end each story thread tends to go its own way regardless of how another might have turned out
and i wasn't really thinking steam punk
think more of the world of full metal, has science but its also a type of magic
