Gods of Ragnarok
From Tardis Wiki, the free Doctor Who reference
Rag, Nag and Ok, a.ka. Gods of Ragnarok were three evil Old Ones from the time before the creation of the Universe. They possessed the ability to exist in multiple times and dimensions simultaneously.
The Gods created the Land of Fiction to entertain themselves, but grew bored and abandoned it. (NA: Conundrum)
They existed for a time on Segonax where they took over the Psychic Circus and appeared as a man, a woman and a little girl in the audience. (DW: The Greatest Show in the Galaxy)
