The Endor Holocaust
What happens when you detonate a spherical metal honeycomb over five hundred miles wide just above the atmosphere of a habitable world? Regardless of specifics, the world won't remain habitable for long.
That's from the Endor Holocaust. Even though I resent the Ewoks as the most concrete example of the muppet-isation of Star Wars, I am appalled to learn of their most likely fate at the hands of the Rebels.
