The Psionic Suppression Grid was developed in the early 33rd Century by Mikagis researchers examining past technology that interacted with psionics such as the Psi Blocker, Psi Grenade, and Psionic Refractive Armor. Psionists report the net effect of the network is that the results of using psionics are hampered greatly, but the network itself does not cause pain or unconsciousness like earlier technologies. La Terre is known to have utilized the network on a planetary level.
