This section contains a summary of Babylon 5's story arc (the 5-year plotline) up to, but not including, "A Day in the Strife." Note that this is chock full of spoilers!
"Matters of Honor" brought Marcus Cole, a Ranger, to the station; he led Sheridan and Delenn to a new ship, the White Star, a combination of Minbari and Vorlon technology. Pushing the White Star to its limits, Sheridan destroyed a Shadow cruiser. Londo attempted to sever his ties with the Shadows. Morden met with a Psi Cop, apparently far from the first such meeting.
