Bedlam Outlands

From Tardis Wiki, the free Doctor Who reference

The Bedlam Outlands was a location where an unknown race (described only as 'the most horrible creatures you could possibly imagine') were based and tortured their captives. John Hart found Gray chained to a ruined city there, with the creatures having long abandoned the Outlands and all of their other former captives there dead. (TV: Exit Wounds)
