Tython played a major role in the Star Wars Extended Universe, but it's been reinvented slightly for the modern Star Wars canon. This planet may not have appeared much in Star Wars past, but it does contain the most intriguing part of Jedi lore. However, that may only be the beginning of the history we'll learn this season, as Ahsoka Tano ends The Mandalorian Chapter 13 by sending Mando and Grogu to the planet of Tython. We learned Baby Yoda's name after more than a year of referring to him as 'Baby Yoda,' and Season 2 Episode 5 finally had some light shed on his murky past.
After months of rumors, Rosario Dawson finally brought Ahsoka to live-action. The Mandalorian just gave us everything we wanted and more.
