A shed can be a dark place (5)
I believe the answer is:
hades
'a dark place' is the definition.
'hades' can be an answer for 'place' (I have seen 'gloomy place' mean 'hades' so perhaps 'place' could also mean 'hades'). I am not sure about the 'a dark' bit.
'a shed can be' is the wordplay.
'can be' is an anagram indicator.
'a'+'shed'='ashed'
'ashed' anagrammed gives 'HADES'.
Can you help me to learn more?
(Other definitions for hades that I've seen before include "It's hell in the Greek shade" , "Inferno" , "gloomy place" , "The underworld where the souls of the dead live" , "Hell of Greek myth" .)
