The Klingon counterattack has reached the Cardassian system itself. The surrounding planets must be captured, before a final assault on Cardassia Prime and its powerful defenses can be mounted. Gul Kentar is able to escape as Cardassia Prime falls, but Martok and his fleet are close behind.
Then the coward flees to his secret base in the Hurik system. Here, he must be destroyed, along with the quantum singularity technology the Cardassians have developed, which is how they are bringing Species 8472 into the galaxy. The station is destroyed and Kentar’s ship is destroyed in combat with Martok’s armada.
