I’m listening to this song now while reading Star Wars Thrawn. No, it’s not a direct allusion to the Thrawn of Rebels (because there it seems to me a little different from the books), but it definitely helped me get in the mood.
@madcollector I read the first 50 pages and I also got the feeling it’s Rebels’ Thrawn other than the Thrawn Trilogy. I found some minor inconsistencies (I think, but it’s too early, I need to read more), but so far so good.
