Do we accept novel blurbs and publisher summaries?
They're not always too unreasonable, but are they canon?
I'm thinking of a few in particular:
- Marka Ragnos being dubbed "the most powerful of the most powerful" in Tales of the Jedi: The Golden Age of the Sith's publisher summary
- Darth Bane being "the dark side's most powerful master" as of his time according to the back cover of Dynasty of Evil
- Darth Plagueis being stated to be the most powerful Sith Lord who ever lived up to and of his time in the back cover of Darth Plagueis
- The internal flap of Legacy of the Force: Invicible describing Caedus' aptitude of the Force as having surpassed even Darth Vader's
So, do we accept these?
