We can assume it will be set back around 30 years, or the emperor would have somehow returned immediately after the Battle of Endor. Hemlock will be toast for sure.
Given that the Imperial Remnant are actively working on getting Project Necromancer back on track in Mandalorian season 3, we can assume it was sometime after that.
It's possible they take a similar line as the Dark Horse Comics non-canonical Dark Empire series. The emperor's clones are reanimated by his force ghost, but they decay rapidly, so he actually goes through a whole series of clone bodies.
Yup. Palpatine could be more undead as well vs a clone body.
Witches and all that.
Dark Empire had its issues but the clone stuff was explained fine. Makes more sense post 2002 than 1991.
