Defender
Merr-Sonn's high-altitude ion mine, the Defender was used extensively by the Empire to blockade rebellious worlds. The mines were deployed in orbit, and were equipped with cloaking revvers and scatter beams to render themselves nearly undetectable. Any ship travelling within 10 kilometers of the mine triggered the device, which fired ion energy at the ship similar to an ion cannon. The disabled ship was forced to float in space until boarded by Imperial forces.
