Nullification resin was a wrapping used by the Jedi Covenant on Sith artifacts to dampen their random malevolence. With resin surrounding the devices, Jedi could not feel the evil emanating from them. The resin was placed on countless artifacts in the Sanctum of the Exalted on Odryn, including Ludo Kressh's pedicure set and Exar Kun's lightsaber. Up to three grades of the resin were known.
