Rigelian Seventh Fleet
From Tardis Wiki, the free Doctor Who reference
The Rigelian Seventh Fleet was a space fleet in the Rigelian military. It disappeared when Omegon took it into his realm. The Rigelian fleet commander spoke with K9 Mark I about the disappearance, calling it "a total impossibility" and demanding that he find it. After Omegon was defeated, K9 returned the Rigelian fleet to the commander. (PROSE: K9 and the Time Trap)
