K'Thủa

K'Thủa is a fictional location, concept, or entity originating within the Cthulhu Mythos, primarily associated with the works of August Derleth, who expanded upon the creations of H.P. Lovecraft. Unlike many locations described by Lovecraft, which evoke cosmic indifference and ancient horror, K'Thủa is often presented as a place or entity tied to elemental forces, specifically air.

In Derleth's interpretation, K'Thủa is often connected to the Elder Gods or forces of good, opposing the Great Old Ones like Cthulhu. It represents a counterpoint to the chaos and destructive potential of the malevolent entities in the Mythos. Its precise nature and significance vary depending on the specific story in which it appears, but generally it is a force for order and balance within the cosmic struggle.

While not as widely recognized or deeply explored as some other aspects of the Cthulhu Mythos like R'lyeh or Azathoth, K'Thủa represents a significant element in Derleth's systematization of Lovecraftian horror, introducing a degree of moral duality not always present in Lovecraft's original stories. It has been used in various stories, games, and other media inspired by the Cthulhu Mythos, typically retaining its association with air and its role as a potential ally against the forces of darkness.
