I read the Darth Plagueis novel, and didn’t come away thinking of him as an all time great, nor his master. They certainly don’t match up to people like Vader or Revan.
Plagueis was a true Sith; never in his life had he considered betraying the Sith so Vader shouldn’t be in this conversation. Being a Sith is far more than using the Dark Side; it’s being committed to it until the last sliver of life leaves a Sith’s body. As for Revan he has more feats under his belt and may be a slightly more interesting character but Plagueis is superior in terms of his knowledge of the Dark Side (and other esoteric facets of the Force via his midichlorian manipulation) and he did far more for the Sith Order in terms of ensuring their dominance over the Galaxy. There’s not enough of Tenebrous to really even render judgement on him.
Sorry, I thought you were basing your “all time great” thing on them as characters. In that respect, I found both Plagueis and Tenebrous very mediocre.
I found Plagueis’ musings to be interesting and I was also interested by his quest for immortality and how his obsession with it affected him. Other than that there’s not much to say other than his backstory is pretty cool imo.
Darth Bane too.
Darth Bane bites a guys thumb off within the first 10 or so pages of Path of Destruction…but ok. The sabacc scene was long but the clashing of ideals was interesting to read and established that Bane’s surroundings was already molding him to a being with philosophies that are akin to the Sith’s. And from there the plot really gets moving. To each their own I guess.
