The Armorer reappears in The Book of Boba Fett in "Chapter 5: Return of the Mandalorian". Now hiding in the ringworld of Glavis, the Armorer and Paz Vizla (the only two survivors of the massacre on Nevarro) are found by
The Mandalorian Season 3 Subtly Retconned The Armorer
However, The Mandalorian season 3 makes it clear that the Armorer that Din Djarin knows is the one and only Armorer, whose duties and knowledge have been passed down for generations. In the process, she's become a mythical figure of sorts, a Merlin-esque archetype.
There's some wriggle room in the Armorer's quote: "Death Watch exists no more." She could also be expositing that the Children of the Watch split from Death Watch eons before the Clone Wars. She may have never even been a part of the Death Watch's generation but was educated of her covert's history with them.
Emily Swallow plays The Armorer in The Mandalorian Season 3.
She kept the tradition of the Mandalorian people alive by forging beskar, but she also reminded the Tribe to never remove their helmets in the presence of another, claiming this was the Way of the Mandalore.
After the episode aired, a theory started circling the Star Wars fandom that The Armorer was actually an Imperial spy during Season 3. While that proved to ultimately not be the case, here's evidence that made fans believe their theory.
Some have theorized she is Sabine Wren, a Mandalorian warrior and one of the main cast members of the animated television series Star Wars Rebels. Others have argued the horns on her golden helmet and the red color of her armor are references to Darth Maul, a Star Wars antagonist who at one time ruled the Mandalorians.
The Armorer does more than show respect for Bo-Katan; she also parades the warrior without her helmet in front of the Children of the Watch — and in doing so, the Armorer sends a clear message to her followers that they also must accept the help of people who are not so strict about the Creed.
But while Gideon's horns may be a reference, The Armorer's are still unexplained. They may simply be a remnant of the Maul-adjacent extremist Death Watch movement, which she revealed crumbled because of infighting, but they could be a hiding-in-plain-sight indicator that her intentions aren't all they seem.
Her fervor for the Mandalorian code has inspired and condemned Din Djarin throughout her life. Yet, nothing is really known about The Mandalorian character. One theory contends she may have a deep connection to the Clone Wars: that the Armorer is actually Rook Kast, former follower of Darth Maul.
Din Djarin, the Watch's former hero, wasn't born into Mandalorian culture. He was rescued and inducted as a foundling by a member of Death Watch. Interestingly, as Wookiepedia points out, the French version of The Mandalorian translates Children of the Watch as Les Héritiers de la Death Watch.
Bo-Katan may not remain a member of the Children of the Watch, but she is living among them for a time, acknowledging her own biases and judgements. The episode may be called “The Convert,” but Bo-Katan probably won't have a sudden crisis of faith, she's just trying to be a good guest.
It's explained: "There is a theory that Satine and Bo-Katan had another sibling (could be a brother, in which case the copium theory would be that the Armorer is their sister-in-law), and that is because of Korkie, who refers to Satine as his aunt (maybe to Bo as well, can't remember; Bo's definitely not his mom though ...
The Armorer is revered and powerful because she is the one that creates the armor for her covert. She is a master of her craft as we've seen her fashion armor for Din, Bo-Katan, and even Grogu.
When Djarin reunited with the surviving members of the Tribe on Glavis Ringworld, the Armorer informed him that beskar was only for armor, not weapons, as the spear was capable of piercing Mandalorian armor. Djarin had her melt the spear and reforge it into a garment for the foundling Grogu.
It's quite possible the Armorer is Rook Kast. However, thus far, there's no definitive evidence.
The belief is that the blacksmith aligned with Darth Maul during the tumultuous times and there's plenty of evidence stemming from her own armor and interaction with Paz. The theorist pointed out the Armorer's own armor as a key reason to why she served alongside Maul during the Clone Wars.
Fans have also speculated that The Armorer is actually Rook Kast, who fought alongside Maul during the Siege. Maybe Rook Kast was Maul's successor, and after his death she transformed the Crimson Dawn into the Children of the Watch, making it a Mandalorian group much like the Death Watch was.
No, Captain Phasma's armor, as well as her blaster, is actually made from Chromium. If Phasmas armor was actually made from Beskar it would not have been able to break like it did in her duel with Finn in on the Supremecy.
The symbolic color index for the Mandalorians armor is: Black = Justice. Blue = Reliability. Gold = Vengeance.
Mandalorian armor was traditionally made out of almost indestructible Mandalorian iron (beskar), but this was rare and expensive, so many Mandalorians, such as Jango and Boba Fett, opted for less durable materials instead, such as durasteel or duraplast.
Din Djarin's armor was originally worn in appearance, though it was later rebuilt around 9 ABY, when he used beskar to change the appearance of the armor. Later, the armorer of his tribe engraved a mudhorn signet on his pauldron to represent his clan.
Religious Mandalorians like Din Djarin prove their devotion to the creed by never removing their helmets. And native Mandalorians are the ones you see removing their helmets. And that's not to say native Mandalorians can't also keep the creed.
Then, in season 2 episode 8, “Chapter 16: The Rescue,” Djarin removes his helmet willingly to show Grogu his face before Grogu departs for his Jedi training. Even though the removals seemed warranted and even commendable, they weigh heavy on Djarin's mind, and he admits them to the Armorer in The Book of Boba Fett.
Clone Wars
Notably, the Dagoyan Masters of Bardotta regarded the Jedi as thieves and kidnappers because of that practice. Some Mandalorians, most notably members of Death Watch, held a grudge against the Jedi for their perceived crimes against Mandalore during the Mandalorian-Jedi War.
