Ogre unyielding in pastoral setting (7)
I believe the answer is:
orchard
'pastoral setting' is the definition.
(pastoral means relating to nature or agriculture)
'ogre unyielding' is the wordplay.
'ogre' becomes 'orc' (both are horrible fantasy creatures).
'unyielding' becomes 'hard' (I've seen this before).
'orc'+'hard'='ORCHARD'
'in' is the link.
(Other definitions for orchard that I've seen before include "Trees bearing apples perhaps" , "Fruit-growing area" , "Area set aside to grow fruit" , "Clump of fruit trees" , "Field for growing fruit" .)
