Ciridium

"Beskar is enormously strong, able to deflect blaster bolts and even lightsaber blades. Yet it is light and flexible, particularly when forged with carbon and ciridium."

―Tor Vizsla, Ba'jurne Kyr'tsad Mando'ad^[1]

Ciridium was a substance included in the Mandalorian armors.^[2] The substance was noted in Ba'jurne Kyr'tsad Mando'ad, a manifesto of the Death Watch Mandalorian splinter group. The document was supposedly written by the movement's leader, Tor Vizsla—although the Death Watch's opponent Jango Fett doubted its authenticity—and was eventually included in the book The Bounty Hunter Code by Jango's son, the bounty hunter Boba Fett.^[1]
