Phryne
From Tardis Wiki, the free Doctor Who reference
Phryne was the home planet of the Phrynians. It (but not its moon) was hidden behind an invisibility shield. After the Daleks discovered the moon, they figured out how to pierce the shield and invaded the planet. (COMIC: The Archives of Phryne)
The Daleks' conflict with Phryne was recorded in the Dalek Chronicles, a set of story-cubes which made their way to Earth by 2094. (PROSE: The Dalek Chronicles Found!)
