Will it be relevant to the ST? Consider how zealously GL protected this secret from the EU; with the droves of SW literature that we have, there is no inkling about Yoda's personal history. There have been some attempts to elucidate this subject, but orders to halt them came down from top men. "Top...men." It's always seemed odd that GL would keep this detail to himself for no apparent reason. Perhaps because it featured prominently in the (formerly uncertain) future of SW?
