Interactuss
Interactuss is a fictional concept that appears in the works of author H.P. Lovecraft and his literary successors. It refers to a cosmic entity or force of immense power and unknowable nature, often associated with the void beyond the stars or the spaces between dimensions. The term itself is not consistently defined across Lovecraft's stories, but it generally evokes a sense of alien, non-terrestrial intelligence or existence that operates on principles entirely foreign to human understanding. Interactuss is not typically depicted as a benevolent or malevolent being in the human sense, but rather as an indifferent force that can have profound and often destructive effects on the physical and mental states of those who perceive or encounter it. Its influence is usually subtle, manifesting as unsettling dreams, inexplicable phenomena, or a slow erosion of sanity. The concept serves as a key element in the Cthulhu Mythos, contributing to the overarching theme of humanity's insignificance in the face of vast, incomprehensible cosmic powers. Writers expanding on Lovecraft's universe have sometimes used "Interactuss" to describe specific entities or the underlying fabric of reality that gives rise to these entities.
