Kraken (Unnatural History)
From Tardis Wiki, the free Doctor Who reference
The Kraken is a species that originated from a higher dimensions and is big enough to flatten San Francisco. It can be found floating in the void where it twists itself through almost incomprehensible space. It is known to feed on exotic matter, plumes of raw cosmological power, as well as fountains of energy from the upper reaches which are undetectable in normal space. (EDA: Unnatural History)
The Kraken are one of the predators in the vortex, along with the Chronovore and the Swimmers. (EDA: The Shadows of Avalon)
