Jalian 17

Jalian 17 was a planet in Mutter's Spiral close to the refuelling station on Hurala. The Tenth Doctor noted how it was "all right for a party, if that’s your sort of thing." (NSA: Prisoner of the Daleks)

Due to it's close proximity to Hurala, Klechton was likely located in the Lasron solar region in the Kappa Galanga sector
