Plath
From Tardis Wiki, the free Doctor Who reference
The Plath were a race who had used advanced quantum computers for ten thousand years. These quantum computers were far more useful then the human-made computers, such as the TITAN Array. (PDA: The Quantum Archangel)
- The Sixth Doctor was involved with the Plath in an unknown, but apparently unpleasant, event. It is unknown when this occurred.
