This is confusing. Isn't Rebels Canon due to the fact that Disney wrote it? Much like Clone Wars was Canon due to it being Lucas? Or has Disney said that Lucas is canon and we have a new canon that we will call legends?
Bear with me. I used to be good at the whole canon vs EU
Rebels is Canon.
That is why we're talking about Thrawn being Canon at all.
Until he was in Rebels, he was only a Legend.
CANON consists of:
The Original 6 Films by Lucas
The Clone Wars by Lucas/Filoni
++anything new produced by Disney after April 14(?), 2014.....
This includes the Rebels Series, as well as the new Books and Movies produced by Disney.
For Example:
Thrawn is in Rebels, and he is canon. But he has no Background.
Timothy Zahn will be releasing a new book next year (?) that has Thrawns "Canon" Background in it. That may cherrypick details from legends, but only what is written in that Book, will be considered "Canon" and "The Truth" of the background.
Gone are the days of Film canon, Core Canon, Lucas canon... GONE, GONE GONE.
Now, there is One canon.
The Canon of Disney, if you wish to call it that way... But truly, its the Canon of LFL and the Holocron... Where all new stories are essentially vetted by the Lucasfilm Story Group, to make sure they make sense in the greater galactic picture.
