The Dampener was a type of space station created by the rogue Vulcan scientist T'Uerell. These stations contained a large ring shaped construct by their side and were composed of solid Neutronium making them almost impenetrable. In 2272, T'Uerell deployed a number of these stations around the Kettaract research station and were used to destroyed a Federation Starfleet taskforce by weakening their shields with the resulting power being transmitted into the defense grid which destroyed the intruding starships.
