Kingdom of Beasts

From Tardis Wiki, the free Doctor Who reference

The Kingdom of Beasts was a bleached white mirror image of Earth, with ruined and dusty replicas of locations on Earth London therein. The Kingdom of Beasts was where the Babewyns originated from. After the Doctor killed the King of Beasts, the Kingdom was closed off from the rest of the universe. (EDA: The Adventuress of Henrietta Street)
