Eh, the Sith weren’t really new when the PT came out. The novelizations and the EU had already prominently mentioned/featured them prior to TPM’s release.
I know the novelizations called Vader the “dark lord of the Sith”, but I think its current meaning wasn’t officially revealed until TPM.
Were they in the pre-PT EU too? I admit I don’t know much about the EU except for a few comics and videogames, so please tell more about it.I could have sworn the Thrawn Trilogy called Vader a Dark Jedi. It’s been a while since I read it so don’t quote me on that.
You’re probably thinking about Joruus C’baoth.
(He was a Jedi turned evil/mad, but he was never affiliated with the Sith so he was simply referred to as either a Jedi or Dark Jedi in the trilogy.)
However, I never really understood what made Vader and Palpatine Sith, even more so after the PT. Neither of the act very Sith-ish, maybe Palpatine to some degree, but definitely not Vader. The again, I haven’t read any PT material in 10 years so I wouldn’t really know what makes a Sith a Sith. I do however feel that they both fit very ell into the definition of Dark Jedi (especially Vader).
