Aceton Assimilator

Weapon used by the ancient Menthars in their war with the Promellians a thousand years ago. Aceton assimilators could drain power from distant sources (such as a hostile ship), then turning that energy into deadly radiation to kill the ship's crew. Hundreds of thousands of these devices were placed in an asteroid field near Orelious IX, trapping the Promellian cruiser 1,000 years ago. While still active now, they trapped the Enterprise-D in 2366.
