to security, who quickly apprehend Dureena. Captain Anderson (Tony Todd) of the EarthForce destroyer Charon, arrives and meets with Sheridan and Dureena; all have been alerted to each other by Galen. Dureena turns out to be a refugee from Zander Prime, a world destroyed during the Shadow War by a Shadow Planet Killer; she initially blames Sheridan for his inaction, but upon learning of the Drakh, realizes that they are responsible for what occurred. The team sneaks out of Babylon 5 during the night on Charon, and they travel to the shipyards and take Excalibur and Victory out to visit Daltron 7. They arrive to find the once pristine world scorched to ruin and they discover the body of the fourth member of their party, a Drazi, on the surface. The Drazi's records indicate that Daltron 7 was destroyed by the Drakh less than a week before in a test as a prelude to their attack on Earth, confirming that the Drakh are in possession of a Shadow planet killer.

Drake is subdued and forced to release the details of the Drakh attack fleet. Sheridan and Anderson arrive in Earth space just ahead of the Drakh fleet and organize the Earth and Alliance fleets assembled to repel the attack, and a massive battle ensues when the Drakh emerge. During the conflict, Sheridan and Anderson venture into the Shadow planet killer in search of a primary component: the device is a well defended planet-sized web of interconnecting joints filled with core-penetrating nuclear warheads. Dureena uses her guile to correctly isolate the master control hub just as Victorys weapon systems are irreparably damaged. Anderson and his
