dayless
Without any dawn
Dayless means without daylight or without days—perpetually dark or outside the normal passage of time.
The word is rare and literary, evoking places where the sun never reaches: the dayless depths of the ocean, a dayless winter in the far north.
It can also suggest timelessness or an existence removed from ordinary temporal markers.
