"Master Race"

The Starship Gladiator discovers a Federation starship that has been missing for over two centuries. After crossing the galaxy, the USS Zavala never attempted to come home. Why? What is locked within her hull that holds the key to saving thousands of worlds.

Over a millennium ago, the planet Wope was wiped from the galaxy. The only reminant of its existence surviving today is a small asteroid field in the Romulan Neutral Zone. What caused this catastrophy, and why? Only three weapons have ever been documented as capable of destroying a planet. The Planetkiller, Species 8472's bioship formation, and the Omega Explosive Device employed by the Cyrollan and Krynn. Are one of these responsible?
