Taking official statements as incontrovertible.
I do it, cause why the **** not?
Especially when it signifies the writers' intent. Like Meetra Surik and Kreia being <<<<<<< Revan.
It definitely helps rank characters. Like the statement
Meanwhile, on the far side of the galaxy, the Sith Empire has grown powerful through centuries of dark Force wielding and magic and the hundred-year rule of the greatest Dark Lord of the Sith, MARKA RAGNOS.Since there was only 1 Dark Lord of the Sith at the time, it can be inferred that Marka Ragnos had greater Force strength than Tulak Hord or Ajunta Pall (for the record, I prefer both of the latter as characters–especially Tulak Hord–but facts are facts).
And there will never be a more powerful Sith that preceded Sidious.
Anyone else have any examples they like?
