It is near the end of 2262, and many changes are abound. Londo, G'Kar and Garibaldi have already left, and Franklin will be taking up his new position on Earth shortly. Elsewhere, Lennier makes a terrible choice and must face the consequences. Finally, Sheridan and Delenn leave for Minbar, where the Interstellar Alliance's recently finished headquarters are located.

A technomage named Galen predicts an imminent attack by the Drakh, the old allies of the Shadows, seeking revenge against Earth. Through dreams, a thief, a captain, and a president are brought together to head them off. The president is John Sheridan. Because of his irrational behavior, Sheridan's friends begin to wonder about his sanity. It's up to all of them and two prototype battlecruisers, the Excalibur and the Victory, to stop the fleet and their planet-killer. But is there more to the Drakh's plan?
