Sagittarius A*
From Tardis Wiki, the free Doctor Who reference
Sagittarius A* was a supermassive black hole. In her 2323 paper Love & War: A Meta-Historical Investigation of the Dawn of the Cosmic Revolution, Dr Olivia Kagg Waldermein stated that the black hole "now hovers menacingly at the legendary coordinates of the Gods' Base of Operations," the former home of the Lesser Time Elementals, "and, as far as current history is concerned, it always has."
