A lot’s been said abut the similarities between this movie and the Dark Empire comics, but today it occurred to me that the whole secret-armada-in-the-Unknown-Regions bit is very Dark Force Rising. And the Death Star guns on Star Destroyers is more than a little Darksaber. I think it might be fun to catalog all the recycled Legends elements in this film.
Terrio is supposedly an EU fan so it makes sense.
