We occupy obscure dens in the country (6)
I believe the answer is:
sweden
'in the country' is the definition.
(I've seen this before)
'we occupy obscure dens' is the wordplay.
'occupy' means one lot of letters goes inside another (inserted letters occupy or enter the word).
'obscure' indicates anagramming the letters.
'dens' anagrammed gives 'sden'.
'we' put into 'sden' is 'SWEDEN'.
(Other definitions for sweden that I've seen before include "Nordic country" , "N. European country" , "European kingdom" , "Its capital's Stockholm" , "Member country of the European Union" .)
