'in which enlightenment counters' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'darkness?' is the wordplay.
I cannot quite understand how this works, but
'darkness?' could be 'night' (night is a period of darkness) and 'night' is found within the answer.
The remaining letters 'school' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
