The background characters in Maz Kanata’s castle is apparently already getting they’re own Disney canon backstories.

This guy’s apparently called Captain Ithano according to the back of the book, and although they seem to go for a more OT kind of feel they’re not shying away from using the PT lore.

That woman we saw sitting on top of the large Thrandoshian looking guy is also going to get her own book and is called Bazine.

And these guys that we briefly saw in the B-roll footage from D23 is also getting a story (which looks really weird);

It seems like the new Disney EU is going to give every single background character as much of a backstory as the old one did. Not that I really expected any less, but what I’m most curious about now is what they’ll do with the old background characters from the OT and PT. Will they eventually just re-write everything about Sy Snootles, Figrin D’an, etc, or will they just recycle the old stories.
