lightlessness

Absence of illumination

Lightlessness is the state of being without light—complete darkness or the absence of illumination.

The word appears in literary or atmospheric descriptions: the lightlessness of the cave, the oppressive lightlessness of a moonless night.

It emphasizes the totality of darkness more than simply saying "dark."
