After being punished for retreat from combat, Ranger David Martel is given command of the Liandra, a haunted 20-year old Minbari fighting ship. He's escorting ambassadors to a secret archaeological site, the oldest city on record and a clue to a dangerous ancient race.

Babylon 5: The Legend of the Rangers takes place in 2264 after the wars are over and a new age of space exploration has begun. The Interstellar Alliance has been organized to establish and maintain peace among its member worlds, including Earth. The Rangers are an elite military force made up of hand-picked young, smart, dedicated human and alien members who combine the high-tech elements of space travel with the idealism and honor of the knights of old. They encounter a previously unknown alien race whose lethal power is far greater than any force previously known to Earth or any other world in the Interstellar Alliance.
