Expanded Universe IS relevant . . .
As I stated on the old board, Expanded Universe IS relevant. Where do you think GL got the idea of a double-bladed lightsaber from? The Sith War was written YEARS before Episode 1 was written. Exar Kun IS relevant, because he invented the double-bladed lightsaber and Darth Maul used one in Episode 1. That proves EU IS relevant. There are other examples also, but I'll let you find those out on your own.
