I do listen. Whoever said this was Colimbia's Twelve Colonies?

"This was the third time they'd taken Coruscant...." clearly indicates that this is the third recursion of the Star Wars galaxy. 

 For some amount of spoilers, they took a single recursion of the 12 Colonies but decided against any others, their resources were far too limited to merit repeated invasions. This Columbia's recursion is untouched, their Columbia having been destroyed. The galaxies of the 12 Colonies are barren for some reason and devoid of life. They make for poor slave stock. It might, should the grest Endevour permit make for some fascinating study. Why is it that this Galaxy alone is so barren? Where were the ancient races that seeded the galaxiesof other recursions?

Mind you, now all that is totally ruined.
