The H.P. Lovecraft Wiki

This subject contains information from the "Lovecraft Circle" Myth Cycles, and while guided by HPL are not based on his work alone. Fthaggua, also known as The Lord of Ktynga or The King Regent of the Fire Vampires, is an entity which appears in the H. P. Lovecraft-inspired Cthulhu Mythos.


The King Regent of the Fire Vampires, Fthaggua appears as a great flickering ball of cold blue flame. It dwells with the Fire Vampires within an enormous edifice upon the surface of the blue comet Ktynga, a celestial body which Fthaggua can guide across the cosmos and which is possessed of many strange properties, not least the incredible heat that it radiates or the fact that it can exceed the speed of light.

It is also the High Priest of the Great Old One known as Cthugha, and may in fact even be its offspring, although this has yet to be confirmed (source?).

Fthaggua was killed by the human scientist Gustav Norby in the year 2339 after it attempted to subjugate the Earth.

The Fire Vampires of Fthaggua[]

These entities are Fthaggua's constructs, literal extensions of itself connected by invisible strands of energy, and dwell with it upon Ktynga. They appear as electrical discharges of bright crimson and, like their lord, feast upon the life-energy of sentient creatures. During this process, the victim will burst into flames as the Fire Vampires consume not only their essence, but their very memories as well. These stolen memories are added to the Fthaggua's gestalt consciousness, which in turn allows it to better plan its raids against the races of the universe, as the Fire Vampires' sole purpose in life is to feed.

Behind the Mythos[]

Fthaggua was created by the late American author Donald Wandrei for his 1933 short story "The Fire Vampires".
