New Naxia

From Tardis Wiki, the free Doctor Who reference

New Naxia was the planet at the centre of the New Naxium Empire.

After Iris Wildthyme and Panda saved the New Naxium Empire from the Slarvians, the Emperor wanted to reward Iris and Panda, including free places at the Pleasure Palace, but the ceremony was interrupted by a Monstron Time destroyer, so Iris and Panda ran back to the Celestial Omnibus.
