Personally, I would very much like to see Kuat. I'm sure you all are familiar. If not, I shall provide a description and photo to help drive my point home. This planet has been mentioned in a lot of works within the expanded universe and I cannot really express how happy I was when it was made canon. Before I get too off topic, this planet holds major importance for the old Republic. Those orbital shipyards that circle the entire planet. Like artificial rings, here is where the literal bulk of the Galactic Republic's fleet is assembled. It would seem strange that a place like this was not targeted by the Sith. This would be an interesting task to accomplish. I think recycling Dantooine, Telos and Peragus ll would get the job done. As for the plot it could be the presence of another faction of the Sith Triumvirate aiming to wreak havoc in the core worlds.
