Malmooth Conglomeration

The Malmooth Conglomeration was the organic home of the Malmooth race located on Malcassairo. It somehow died out by the year 100,000,000,000,000. Humans had taken refuge there many generations before, and the Malmooth began to die with it. Afterwards, the conglomeration was abandoned and Chantho was the last of the entire Malmooth species. Later on in the year 100 trillion, Malcassairo had presumably gone nova and swallowed up the remains of the Malmooth Conglomeration in the process. The Tenth Doctor, Martha Jones and Jack Harkness caught sight of the city before being chased by the Futurekind. (TV: Utopia)
