People seem to go back and forth on how (or if) Fett is alive and will be in the series. I’m not up on most EU or any Lucas SE whatever-the-fucks. Is there any real reason to assume he lived beyond ROTJ?
Not quite sure what you’re getting at? He was alive at the end of the newest episode and this is all set post ROTJ.
In case anyone was wondering, the Krayt dragon does apparently still have legs in canon just like it did in Legends, despite them never being shown in the episode. So basically Favreau got his Tremors/Dune-vibe while still managing to stick to continuity.
