A Gefjun Disturber is a device created by Rakshata Chawla to disable Knightmare Frames. It does this by disturbing the chemical and mechanical processes of the Knightmare's Sakuradite and interior computers and gears preventing movement, which also disables all sakuradite-based technology. In addition, the field blocks the motion of hadrons, radio waves, and microwaves. The Lancelot Conquista was developed with countermeasures that provide a partial defense against it. This resistance has been implemented on later 7th Generation Knightmare Frames. Other than this, it has shown several other uses such as controlling the blooming effect of hadron-based weaponry as well as a defensive shield against hadron and MVS-based weapons.
