Concordance of Fealty

The Concordance of Fealty was the Jedi tradition of exchanging one's lightsaber with that of a fellow member of the Jedi Order. This exchange was considered a sacred bond, symbolizing mutual trust. The tradition included a vow of reciprocal apprenticeship, though this facet was little practiced after the Cleansing of the Nine Houses, a conflict of the Old Sith Wars, and was generally undertaken only by Jedi Masters.

Jedi Councilors Mace Windu and Eeth Koth completed the Concordance of Fealty shortly prior to Windu's departure on a diplomatic mission to negotiate peace between the prince of the Lannik people and the Red Iaro terrorists, approximately 32 years before the Battle of Yavin.

In 22 BBY, Anakin Skywalker and Halagad Ventor engaged in the Concordance of Fealty, unusually for Padawan apprentices, during a mission to the planet Skye. Due to their exchange of lightsabers, Skye native Aragh, in a later account to Rebel pilot Luke Skywalker, would identify the two Jedi pupils as the fallen Jedi Darth Vader, and the bearer of the lightsaber belonging to Skywalker's father Anakin, despite the fact that Vader and the elder Skywalker were in fact one and the same.

On a 22 BBY mission to locate his former Padawan Jedi Master Depa Billaba on his homeworld Haruun Kal, Mace Windu discovered Billaba's lightsaber in the posession of local guide Nick Rostu. Speculating on how Rostu acquired the weapon, Windu mused that it was unlikely to have been a Concordance of Fealty.

During the reign of the New Republic, former Emperor's Hand Mara Jade and Jedi Knight Kyle Katarn were engaged in the reciprocal apprenticeship facet of the Concordance of Fealty.
