WARNING: The following contains spoilers for the Season 2 premiere of Star Wars: The Mandalorian, "Chapter 9: The Marshal," streaming now on Disney+.

Early in Star Wars: A New Hope, old Ben Kenobi rescues Luke and his droids from a Tusken raider attack by echoing an unearthly howl across the canyon rocks. The raiders scattered, and Ben goes on to reluctantly reveal to Luke that he is in fact the Jedi Master the boy was seeking. What he doesn't do in the film, and what the second season premiere of The Mandalorian did, was explain how a single sound frightened away the Tuskens. The answer lies with the episode's stunning reveal of a full-sized and very alive Krayt dragon.

The first sight of a Krayt dragon in canon is not an obvious one, though it's a key image from the original film. Threepio and Artoo, leaving the wreckage of their escape pod, pass a massive, sand-blasted, snake like skeleton. It helps to establish the world of Tatooine, a desperate place where moisture farmers live with countless threats. Like a lot of early Star Wars lore, it was left without further illustration for future creators to run with over the years. While much of it has long since been relegated to non-canon status, interesting pieces keep trickling back into the foreground.

The Mandalorian pushed for the humanization of the Tusken raiders in its first season, making them no longer a generic, frightening race of others living nomadic lives deep in the desert, and giving them nuanced and thoughtful behavior instead. Din Djarin, no stranger to the concept of simply walking in and starting a fight, refuses to do that with the Tuskens. He speaks their language, understands their beliefs, and most of all, acts respectfully towards them. Season 2 opens strong with a return to Tatooine and the Tusken raiders, but goes straight to a Wild West-style reminder that the Tuskens -- a native people who consider their world's scant resources sacred -- often clash with the settlers and their moisture vaporators.

There's a little more lore hiding between old Ben Kenobi's shout and Din's reunion with the Tuskens as they take on a Krayt threatening both them and the Mos Pelgo community. While the novelization of A New Hope written by Alan Dean Foster (but published under Lucas' name) is considered a Legends title, it does add an important conversation between Luke and Ben. It directly identifies Ben's howl as a Krayt dragon howl, although from here it was only mentioned in passing in supplementary materials.

There is another Legends source for Kenobi's understanding of both the Krayt dragons and the Tusken people found in the book Kenobi by John Jackson Miller. While firmly EU, it's a fun, well-received book with large set pieces and chunks of lore that could easily -- and with The Mandalorian's treatment of the Tusken, already did -- slip into canon. It included references to canon events and characters from Kenobi's time on the Clone Wars animated series, gave Tusken characters a major role while fleshing out details of their society and even included its own spectacular showdown with a Krayt dragon as part of its finale.

With Kenobi himself eventually coming to Disney+ with his own series, it's likely that the lost period of his life that ended with a shout in 1997 is going to come home to canon at last, and a lone Mandalorian, just as he already did for pieces of Star Wars Rebels, is helping to pave the way.

Created by Jon Favreau, The Mandalorian stars Pedro Pascal, with guest stars with guest stars Gina Carano, Carl Weathers and Giancarlo Esposito. Directors for the new season include Jon Favreau, Dave Filoni, Bryce Dallas Howard, Rick Famuyiwa, Carl Weathers, Peyton Reed and Robert Rodriguez. The tentatively titled Kenobi, with Ewan McGregor, is awaiting a release date.
