Fthaggua 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. He lives with his servants within an enormous edifice upon the surface of the blue comet Ktynga, a celestial body which Fthaggua can steer 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.

He is also the High Priest of the Great Old One Cthugha, and may in fact even be its offspring, although this has yet to be confirmed.

The Fire Vampires of Fthaggua

These entities are Fthaggua's subjects and dwell with him 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 species' gestalt consciousness, which in turn allows them to better plan their raids against the races of the universe, as the Fire Vampires' sole purpose in life is to feed.

Fthaggua and his terrible race are due to reach planet Earth around four hundred years from now.
