Flissta

Flissta was a temperate world of lakes and hills, that was apparently destroyed by a stellar cataclysm, possibly in 2079. The native Flisk became refugees and asked to settle on Earth. The Doctor likened the planet to the Lake District of England. He claimed to have been near the planet around the year 2059 and witnessed a rift opening across the Opius Expanse, while travelling with the Flisk armada. (NSA: Snowglobe 7)
