Bastion

From Tardis Wiki, the free Doctor Who reference

Bastion was a planet filled with slave labourers of many different cultures and species. It was used as part of the Deindum's war machine. Sixty-eight Grel worked as food-servers of maintenance workers rather than in the pits. (PROSE: Adorable Illusion)

Peter Summerfield and Antonio Tulloch met on Bastion, where they became best friends and eventually fell in love. (AUDIO: The Curse of Fenman)
