Sar Agorn's holocron was a holocron programmed with the personality of Jedi Master Sar Agorn, which served as the holocron's Gatekeeper.

As the Gatekeeper decides who has access to what knowledge within a holocron, Agorn was extremely cautious, only allowing a student to access new techniques if he felt they possessed the proper responsibility to support the new knowledge. Lacking technical know how, such as on the construction of a lightsaber, his vast knowledge of Jedi philosophy and tradition was stored on the holocron, allowing a student to learn new Force techniques or discover the intricacies of the Force as a whole.

This holocron was one of the few surviving storage devices of its era.
