First telecast October 28, 1998, "The Fall of Centauri Prime" was the payoff for the earlier Babylon 5 cliffhanger "Movements of Fire and Shadow" --- and also the opening volley in the series' final four-episode story arc. As the Alliance and Centauri Prime wage war upon one another, Londo discovers that the hostilities were instigated by the Drakh, who have killed the Centauri regent and taken control of his homeworld. Forcing Londo to go along with their plans, the Drakh effectively seal the fate of the Centauri populace. Wayne Alexander appears as the Drakh leader. "The Fall of Centauri Prime" was written by J. Michael Straczynski. ~ Hal Erickson, Rovi
