Star Wars Celebration announced yesterday that Dave Filoni will be in attendance at Star Wars Celebration Europe. Though that’s not a huge surprise, Filoni will also be debuting two brand new episodes from Season 3 of Star Wars Rebels. Filoni also teased on Twitter that a Star Wars Legends character is coming to Star Wars Rebels. He tweeted out the spine of “Heir To The Empre“, which is the first Legends novel to introduce Grand Admiral Thrawn, a character that we heard will be in Star Wars Rebels Season 3.
