Darkness is the state of having no light at all. The moment after the switch goes off, before your eyes adjust.
It works as a plain physical description, as in total darkness, and as a mood, since darkness in a story means despair or evil. Religion and myth use it constantly as the opposite of light. English has some fixed phrases: after dark, in the dark meaning uninformed, and the darkest hour being just before dawn. The adjective is dark and the verb is darken.
