Plastic Conjunction
From Tardis Wiki, the free Doctor Who reference
The Plastic Conjunction was a collection of seventeen food planets which farmed smoke and oil for the Nestene Consciousness. (PROSE: Revenge of the Nestene)
During the Last Great Time War, the food planets were destroyed (TV: Rose) - along with the Nestene's Crownworld of Polymos. After the war the Nestene ended up on the dying Nestenia and swore revenge on the Time War. (PROSE: Revenge of the Nestene)
