I was checking Wookieepedia article on Tatooine and came across this phrase
After a terrible plague weakened the Rakata, the Kumumgah eventually rebelled and managed to drive the Rakata off the planet. In response they subjected the planet to an orbital bombardment that "glassed" (that is, fused the silica in the soil into glass, which then broke up over time into sand) the planet and boiled its oceans away
I am aware of some bombing which took place in Tatooine history, but never knew when it happened.
Which are the episodes which mention Tatooine's history and more specifically the bombing which changed the habitat of this planet of Annakin Skywalker and Luke Skywalker?
