Flissta

Flissta was a temperate planet with lakes and hills. It was apparently destroyed by a stellar cataclysm, possibly in 2079. The native Flisk became refugees and settled peaceably on Earth. The Tenth Doctor likened the planet to the Lake District of England. He claimed to have been near the planet around the year 2059, when one of his past incarnations witnessed a rift opening across the Opius Expanse while travelling with the Flisk armada.
