EU No More
I do own a few books, they're fun and light and exactly what you think they are. Sci-fi fluff in the Star Wars universe.
But alas! These books created CANON - that is, the history of a fictional universe - and the nerds live in this CANNON and every word of it is truth.
So, when Disney said they were discarding all previous Star Wars CANON other than what has appeared in the films, the hard core nerds freaked out. OUTRAGE! STAR WARS IS DEAD! Really, it's hilarious.
As, above, a nerd prepares to burn some of his EU (Extended Universe - CANON) books (I'm sure he has hundreds more). Hurts so good.
