Derleth Elder Sign Seal Cthugha, The Living Flame is an Great Old One created by August Derleth. Its main appearance occurs in the story The Dweller in Darkness.


In essence, it is the same as the name of Cthulhu, of which just a consonant ("l" for "g") and a vowel ("u" for "a") change.


Cthugha's appearance is generally a fireball. However, it is capable of changing shape at will, since it does not have a defined physical structure as it is only a mass of heat endowed with consciousness.

Conceptual information and role Edit

Cthugha gives off heat in its purest form and is capable of causing desertification and killing humans due to lack of water. The only function of this being is to reduce everything to ashes, a purpose for which it uses its subjects, the Fire Vampires.

It should also be noted that Cthugha has an old enmity with the Outer God Nyarlathotep and, like Nodens, does everything possible to make him uncomfortable in one way or another. This is why some speculated in his day that Cthugha could actually be an Elder God, although only this attitude was promoted by rivalry and not compassion towards humanity.


First chronological appearance of this deity, who is conjured together with a horde of fire vampires to drive Nyarlathotep away. (AWD: "The Dweller in Darkness")

Cthugha's appearance is related to the Ur-Nansha lithographs. If summoned, he uses telepathy to reveal to those who summoned him the folly of his actions. He then destroys them with fire vampires, fiery pseudopods, and vomiting flames. In any case, it will incinerate everything around it. (EXP: Call of Cthulhu "Secrets of Morocco" expansion)

Curiosities Edit

  • Derleth created Cthugha in order to give rise to an Great Old One of the fire element, since until then there were none. It was much later that this element was also associated with Azathoth and Aphoom-Zhah.
  • According to the essay The Cthulhu Mythos in Mesoamerican Religion by Richard L. Tierney, the Aztecs could have worshiped Cthugha in the form of the fire god Huehueteotl.

Legacy Edit
