Grogu's chainmail shirt
Din Grogu's beskar chainmail shirt was created after the Galactic Civil War for the Mandalorian foundling Din Grogu. The Armorer crafted it at the request of Din Djarin, the bounty hunter who is also a Mandalorian. After the armor was received from Luke Skywalker, who is a Jedi Master, Grogu was faced with a decision: select the armor or Yoda's second lightsaber. This choice represented following the path of a Jedi or succumbing to his attachment and going back to Djarin. In the end, Grogu picked the chainmail, choosing to return to Din Djarin.
History
The Armorer made Grogu's chainmail shirt in 9 ABY because the Mandalorian bounty hunter Din Djarin asked her to. It was made from Djarin's beskar spear. It was then packaged to be given as a present to Grogu, the Mandalorian foundling, by Djarin. When Djarin showed up to see Grogu, he was stopped by Ahsoka Tano, a former Jedi. Tano took the gift and later gave it to Luke Skywalker, a Jedi Master, who gave the armor to Grogu as part of a choice. Grogu then had to decide whether to choose the armor, giving in to attachment, or the lightsaber of Yoda and the path of a Jedi. Luke also mentioned that it would take Grogu many years to train in the Force, and that he might never see Djarin again because his species lives much longer than humans. In the end, Grogu chose the chainmail and decided to go back to Din Djarin.
Later, after a training session, the Armorer used leftover beskar from other Mandalorians, which they left for foundlings, to make a rondel with a mudhorn signet for Grogu. While sitting by the Forge, Grogu remembered when Kelleran Beq helped him survive Order 66.
