Other mistake: The weaponsmith is smelting Beskar in a furnace in the first episode and the metal is liquid without any sort of incandescence. In the credits roll of episode 3, the artwork shows it red-hot, and in the season 2 finale we see it actually getting red-hot.
Other mistake: Din tracks Grogu down through his chain code and other bounty hunters do the same throughout the series. As stated elsewhere, chain codes were implemented in the year 19 BBY AFTER the end of the Clone Wars and Order 66. We know that Grogu was spirited away from the Jedi Temple during the Slaughtering of the Younglings, so he was already a fugitive by the time they came about. No way they could stop and register him with the Empire while he was on the run from them.
Answer: In (non-canon) Legends, Thrawn was the central character of a trilogy of novels by Timothy Zahn. He was a Chiss officer in the Imperial Navy, who rose to the rank of grand admiral despite being non-human. Thrawn was brought into canon in the Star Wars Rebels series, where he commanded the Empire's Seventh Fleet and led the occupation of Lothal, which was opposed by the series' protagonists including Ahsoka Tano. In the final episode of Rebels, the Jedi and Rebel Ezra Bridger commands Purrgil space whales to drag Thrawn's Star Destroyer into hyperspace, jumping to an unknown location with himself and Thrawn on board. The final scene of the series shows Ahsoka Tano and Sabine Wren leaving Lothal to search for Bridger, and presumably Thrawn.
