Silver Nemesis

Long ago the Doctor launched a mass of validium - living metal - into space; however the validium had a decaying orbit that brought it close to Earth every 25 years. In order for the validium to become active it must have a critical mass. For this reason two pieces were split off the main validium - shaped into a bow and arrow.

The Doctor and Ace visit Windsor in 1988, a time when the validium was next due. Three factions are chasing the validium: De Flores, who possessed the bow, Lady Peinforte, who possessed the arrow, and the Cybermen, who took control of the biggest piece when it finally fell from its orbit.

The three factions fought against each other in an attempt to possess all validium whilst the Doctor, working to his own agenda, ensured that only the faction he wanted possessed the validium.

The Doctor programmed the validium to attack the Cyberfleet that was cloaked in orbit around Earth. When the Doctor announced that the Cybermen should have the full validium Lady Peinforte committed suicide by joining with the validium. When the Cybermen used the validium, the fleet was destroyed.
