A few elements are similar to Princess Mononoke (1997); e.g., a fortress town surrounded by dead forest with a female warrior looking to infiltrate the walls and kill the female leader. Dave Filoni previously stated the Ahsoka was inspired by the character San.
What is that thing?
The Mandalorian: I keep it around for luck.
Lang: You're gonna need it where you're headed.
Ahsoka Tano references Yoda as the only other member of the species that she has ever known. There was another Jedi Master named Yaddle that was also the same species as Yoda and Grogu. She served on the council just prior to the Clone Wars and briefly appeared in The Phantom Menace. In what is now known as the "Expanded Universe", Yaddle was killed sacrificing herself to save Obi-Wan Kenobi and his Padawan, Anakin Skywalker, four years before Ahsoka would have been named Anakin's Padawan apprentice. In the revised "Canon Universe" that is considered the factual history of Star Wars, it is unknown what happened to Yaddle after she stepped down from the council following the Battle of Naboo, though it is believed she spent the majority of her time in the archives following her stepping down and that she was likely killed before or during the Order 66 Jedi purge. It is reasonable to assume that Ahsoka may never have had the opportunity to meet Master Yaddle.
